The neighborhood kids always get a kick out of the decorations we put out. When I came across the <a href="https://www.instructables.com/SonicSurface-Phased-array-for-Levitation-Mid-air-T/" target="_blank">SonicSurface</a> project I knew I could retask it to create something scary for the local kids. </p><p>My current intention is to conceal one 256 transducer array above a dusty surface and remotely trigger (or via simple motion sensor) "Spirit" writing on the surface. I want to make the surface obvious that nothing is concealed within, so the kids can actually touch the dust too... Resetting the dust (baking soda?) would have a bin of baking soda and a servo with compressed air to "redistribute" between groups of kids. </p><p><b>PLEASE COMMENT WITH TIPS OR IDEAS - I WOULD LOVE TO HAVE THE FINAL VERSION WORTHY OF SCARING MY LOCAL NEIGHBORHOOD KIDS (Maybe Adults too?)</b></p><p><b>Build and Prototyping:</b></p><p>So first I went through the SonicSurface build instructions. Their Instructables.com write up is an excellent read and has many useful details. </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgG5bFj8eKO_98OS626uj5iJkHHJap0_sAkkiDFJnz_IHdbwu77UP00YMJPL0URfCXLhWFbpkr4Mrp2mzf81639OfcDmPD1uoW0zaSVcZNdWhFlHquwfDJyhCDzrAuLlALIHhWwi4se2qk/s2643/20210919_125948.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2643" data-original-width="1189" height="707" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgG5bFj8eKO_98OS626uj5iJkHHJap0_sAkkiDFJnz_IHdbwu77UP00YMJPL0URfCXLhWFbpkr4Mrp2mzf81639OfcDmPD1uoW0zaSVcZNdWhFlHquwfDJyhCDzrAuLlALIHhWwi4se2qk/w318-h707/20210919_125948.jpg" width="318" /></a></div><br /><p>Here is one of the completed arrays.

<b><span style="font-size: large;">DIY FUME EXTRACTOR WITH OFF THE SHELF PARTS</span></b></div>
<br />
It's been a while since I've made a blog post. Thought this DIY I put together could help some people get a decent working fume extractor together for their laser cutter without killing their wallet or a HAZMAT team at their door.<br />
<br />
After receiving a Black and Red Chinese 80watt laser cutter / engraver, it became evident I needed a better solution then just exhausting it out the basement window. The only place I had to put it was 20 feet from the window, and after doing a few test cuts of baltic birch I noticed I needed an stronger exhaust fan and also a filter box as close to the unit as possible.
I managed to make a "fairly" inexpensive Fume Extractor that works much better then I has anticipated. The assembly is relatively easy and took me about an hour from start to finish. Here's hoping this project can help others in eliminating the smell of burning wood and acrylic.<br />

I chose to use the airtight food container as a start for my box. I didn't have any large scraps of plywood on hand, and figured I'd go with everything sourced from Amazon..<br />

The first thing I did was locate where the intake prefilter would go (the short truck air intake). I drilled a 6 inch hold and mounted the duct flange. I then attached the prefilter on the inside of the box. I put some silicone sealant around the flange just to be sure everything was still air tight.</div>

The next step was to locate the hole for the activated carbon filter. I had to place that up at the top of the box due to its large size. At first it looks like it wont quite fit, once the hole is there you can slide it down until the filter flange pops through the hole. </div>

<div class="separator" style="clear: both; text-align: left;">
I also placed the prefilter it came with on it. I used a small piece of foam on the other end to hold it perpendicular to the hole. You may need to play around with this to get a flat fit on the flange side. I then applied a liberal amount of silicone sealant here also.</div>

I then inserted the inline blower fan at the exit point (carbon filter), so it "pulls" the air out of the box. </div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
When connected to the Laser Cutter and routed out the window, its actually very quiet. My air assist pump was noisier then the inline fan. I proceeded to run a few projects on the cutter and didn't detect a trace of burnt wood. I will be trying some acrylic later and will provide more updates. </div>

Overall I'm very pleased with this setup. Any questions or comments would be greatly appreciated, I'm sure there's many improvements or cost saving approaches I didn't even think of.</div>

BIG F'N 3D PRINTER BUILD</h2>

<br />
The Reprap's, Prusa's, and other 3D printers are great. I've printed many things with them that have allowed other projects of mine to progress much faster then making by hand or buying them online and modifying them. But... there comes a point where you need a part that is just too big for the print volume or you're just too lazy to print a bunch of small pieces and glue and fit them together. Specifically I would like to start helping the local shelters with custom prosthetic's for dogs or animals in general. Typical print volumes don't accommodate 1 piece designs.<br />
<br />
That's when I said to myself, "Hmmm I'll just buy a bigger 3D Printer and save myself some time." :) Well, I looked on the internet for printers that have about a 8 cubic foot print volume and found that my budget can't compete with some of these offerings online. Having built a few DLP Resin 3D printers and filament based ones in the past, I had some aluminum extrusions, stepper motors, RAMPS controllers and what not sitting around.<br />
<br />
I set out and built a 3D printer with at least a 8 cubic foot volume. It also turns out after having done that, it is too big to get out of my basement without disassembling it... :( <br />
<br />
Note: I had fudged the print volume at 2 cubic feet. It's actually 8 cubic feet. 2' x 2' x 2'<br />

If you look closely you can see a Reprap placed inside the Big F'er</div>
<br />
<br />
<b>Summary of Features:</b><br />
<br />
<ul>
<li>8 Cubic foot print volume (capable of larger with minor changes - i.e bigger cast aluminum plate) - The reason I chose 1/4" Cast Aluminum plate was to make sure it was dimensionally stable when heated. Anything else will most likely warp over that big of an area. </li>
<li>X, Y, Z end stops</li>
<li>Filament runout sensors to pause BIG jobs</li>
<li>Auto leveling bed (4 steppers to support heavy weight, but also allow auto leveling in addition to Z-probe) - used CNC shield board with 4 stepper drivers tied to the Z lines on the RAMPS 1.4 board.</li>
<li>Smoke sensor (separate from main control system - tied to power supply inhibit lines) - no one wants to burn their house down.</li>
<li>FLIR Lepton module to monitor and provide feedback on heat distribution for design improvements.</li>
<li>Dual Bowden extruders (allow fast transits by minimizing weight of extruder sled)</li>
<li>Heated bed (cast aluminum plate and four 280 watt silicone heating pads)</li>
<li>Had been named "Big F'er" because I managed to hit my head many times working on it and assembling it. I apologize to anyone offended by this totally appropriate name. </li>

<br />
<ul>
<li>RAMPS 1.4</li>
<li>Dual Extruder</li>
<li>Heated bed protection off (have fire/smoke sensor) - Plate warms slowly.</li>
<li>100k thermister for heated bed</li>
<li>Calibrated for specific leadscrews and GT2 timing belt</li>
<li>Intend to modify in future for 4 stepper based auto leveling. </li>

<h4>
<b>FRAME</b></h4>
<br />
The first step is to build a rigid frame 3 feet square approximately. I used 3 foot long sections of 8020 2" x 2" 10 series extruded aluminum. With the 8 hole gussets this works very well and provides a rigid and stable frame. <br />

Here's the base assembled with the Y-axis rods and X-axis mounted. Turns out the X-axis design got trashed because there was a little bit of sag over the long distance. You can see the working design below. </div>

One issue encountered with the Y-axis was some sag (the whole reason I redesigned the X-axis... oh well) The 5/8" rods are great, but over 3 feet there is just enough sag to make me question the quality of prints. So not wanting to start over I designed a SAG fixer :) All it really is, is a mount below each Y-axis rod with an 8mm threaded shaft that allows me to push ever so slightly on the center of each Y-axis rod to make it straight. The STL is <a href="https://drive.google.com/open?id=0B8S25d-5M3YybjdGQUJReVVtZ2c" target="_blank">HERE</a>. </div>

Due to the length of my 20mm shaft and Z axis leadscrews I had to put 2" sections of 80/20 extrusions on the Z bed to offset the cast plate up. This worked perfectly. I also used <a href="https://www.amazon.com/gp/product/B0063L4LAK/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=diyengineerin-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B0063L4LAK&linkId=7fc853c7750c893e000320366ae5e154" target="_blank">Ruland MSP-20-F</a> 20mm split ring clamps to set the limit for range on the Z axis. Currently my homing operations simply stall out the Z motors if things aren't level. </div>

The Z end stop mount (STL <a href="https://drive.google.com/open?id=0B8S25d-5M3YyU2ZQb1dFcnZFdTQ" target="_blank">HERE</a>). Is placed on the cross beams above each Z axis linear screw (or approximately around). The theory is each end stop will prevent it's stepper from stalling at the split ring clamp and the bed will level based on that. However I have only wired one of the Z end stops to Z min on the <a href="https://www.amazon.com/gp/product/B0111ZSS2O/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=diyengineerin-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B0111ZSS2O&linkId=d7879c41956b82b440f74eebe60dc785" target="_blank">RAMPS 1.4</a> board. </div>

I bridged the X,Y,Z, and A step lines and connected them to the RAMPS 1.4 Z stepper STEP line. I did the same with the DIR lines. I took 5 volts and ground from the RAMPS 1.4 board and connected it to the CNC Shield too. The Z enable line was then bridged and 12 volt power applied. Works great :)</div>

I've decided to change the way I write my blogs. After reading some of them back to myself, I couldn't help but try to make them a little more fun to read, and if that doesn't work; atleast i'm not bored writing it.<br />
<br />
<h2>
Do It Your Goddamn Self Hydroponic Garden</h2>
<div>
Lester was an average man of slim yet tall stature. His long curly hair lent strongly to the image of a pot smoker. When the word hydroponics would leave his lips in conversation, the first thing people would imagine is him growing pot to support his habit. But Lester just wanted to grow some fucking vegetables, fruits, and maybe some nice herbs he can put in his shitty tomato sauce only he seems to like. </div>
<div>
<br /></div>
<div>
Lester needed something he could have out of the way, be convenient, and not make the yard a dump only the alcohol enthusiasts at the liquor store down the street would be proud of. He also needed to avoid long and wordy run on sentences that annoy the living shit out of him. </div>
<div>
<br /></div>
<div>
So one uneventful day at work he decided to get off his lazy ass and stop by Home Depot and the local hydroponic store for supplies to get started. </div>
<div>

He gently loaded three 4" diameter PVC pipes into his smallish SUV. Being 10' long he had to figure out how not to let one loose on the highway and impale any unsuspecting passer by's. He also bought six 4" end caps and hangars. His list written in chicken scratch looked a little like this, except unreadable by 60% of the population:</div>

Gradually accelerating the car off of the next exit, he sped towards the local hydroponics store. When entering this gleaming metropolis of growing shit, he was greeted by the cashier. After telling of his loose plans for growing stuff he walked out with a couple bags, one of them was a bunch of free samples! </div>

Lester decided a good place to mount the 4" diameter pipes of growing, would be between two fence posts. Like so....</div>

Each pipe was tilted at an angle to allow the solution to travel fairly quickly to allow the roots to absorb nutrient and passively oxygenate the water through agitation. But in the mind of our main character, he just thought it would irk the shit out of people who can't help but notice they're not perfectly straight across. </div>
<div>
<br /></div>
<div>
With his rusty hole saw, he drilled the end caps and put in the barbed hose hookups like a champ. </div>

Depressingly, it turned out Lester didn't pay much attention to the inside lip that runs around the endcap, making it a bitch to get a good seal. Silicone caulk to the rescue! His name should've been Jerry Riggs. </div>

Now it was time to waste an hour searching for a 3.5" hole saw to cut out the basket holes. After wasting an hour or two, he then went down to the local hardware store and bought one. </div>

Wanting to impress his wife and not get divorced because the backyard is starting to look like his workshop; Lester decided to buy a new deckbox. This new deckbox (on sale of course) would replace the existing one. Holding such wonderful things such as cushions of the patio set, and random odds and ends that don't belong in it. The one it replaced would then be retasked to perform a much more important job. A job no normal deck box has the privilege perform. </div>

Lester labored intensely over this tote. He even made labels that don't stick because the backing on them sucks ass. He made a drain hole, a PH up/down hole, pump wire and water out hole. The black plate is for mounting the two peristaltic dosing pumps to pump in PH up and down solution to keep things in balance for the sensitive little baby plants. The plate got scrapped because it was a douche idea with a much better one around the corner. </div>

The Ph Up and Down bottles caps are press fit into the MDF with a smaller hole for the peristaltic tubing to go through. I used a threaded shaft with a plate on the bottom to hold them in place. Theres a nut under the Ph probe board visible in the picture above. Notice the check valves. They're going to be moved to the very end. I want to be sure only what I pump out will be released into the nutrient solution. <br />

I cut 1" square holes for the legs to go through on the lid. This also allows for clean routing of the air and temperature lines. The H20 sensor will be used for leak detection. As far as rain sensing goes for an outdoor setup I'll just poll an online resource once I add Wifi :)<br />

UPDATE: 7/13/2016<br />
<br />
Now that there's more traffic to the blog after the friendly Hackaday post; it's really lit a fire under my ass to post more information and refine the design. As always I appreciate any feedback.<br />
<br />
Currently, I'm fixing some software and wiring issues. My relay control signals aren't making it the 4 shitty inches or so to the relay driver board. It's like there's a strong 50 ohm pull up on these lines. I suspect a solder short or ground plane short in the level shifter board I used for the TFT display... I plan on fixing that soon.<br />
<br />
In the meanwhile here a pic of the babies I'm getting ready for the main system.<br />
<br />
I drilled a crap ton of holes in a 32 gallon tote and filled it with 1/4 strength hydroponic solution. They seem to really like it. I have a <a href="https://www.amazon.com/gp/product/B00HP28UU8/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=diyengineerin-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B00HP28UU8&linkId=4c785cf4c5a6dcc0a8ac824b64b5aac8" target="_blank">solar bubbler</a> keeping it oxygenated. <br />

All settings are adjustable and can be saved to EEPROM so that they are restored on reboot.<br />
<br />
<b>SYSTEM TIMING:</b><br />
<br />
Current Settings are as follows for the Water AND Air bubbler<br />
<br />
10 Minutes on (allows complete saturation of all pipes with 8 minutes of flow after saturation)<br />
30 Minutes off (allows 4 minutes to drain, and 26 minutes of idle time)<br />
<br />
Some people do equal times on and off, however with a solar system I wanted to decrease the duty cycle so that it wouldn't just die in the middle of the night. <br />
<br />
<b>SYSTEM FAULTS:</b><br />
The system is interrupted and a warning is issued to the screen under the following conditions:<br />
<br />
-Tank Empty switch active<br />
-Motor temp exceeds 140 deg F<br />
-Water temp exceeds 120 deg F<br />
-PH meter fault (min or max reading)<br />
-PH adjustment unresponsive (4 PH up or down cycles without >0.4 Ph value change)<br />
<br />
The air bubbler function will continue despite any fault conditions. Nobody likes stagnant water.<br />
<br />
<b>TDS Sensor (potential)</b><br />
<b><br /></b>
As a "side" side project I'm hoping to figure out how to interface to this <a href="https://www.amazon.com/gp/product/B00IDBZ1A2/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=diyengineerin-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B00IDBZ1A2&linkId=77e4722a57d80bc76bf84ab15c0a9c1c" target="_blank">TDS-3</a> unit to get the dissolved solid reading. I have two more peristaltic pumps I'll throw on to keep the nutrient concentration level. No guarantees on this one though.<br />

Time to pull out the oscilloscope. Maybe there's a serial stream coming out, or even a voltage value that scales to the reading. The bottom fat pin is the temp sensor. <br />

After getting a new target bow, I decided to install my peep sight. Needless to say, it pays to use the right tool and a bow press. I managed to nick my string and pretty much make it useless. Wanting to do it right the next time I bought a nice used Sureloc Xpress bow press. The older model of course that doesn't do parallel limb bows. At one time they made a USL adapter kit for this to allow you to do more modern bows. But I was unable to find these used or new anywhere.<br />

I decided to take matters into my own hands. After searching for hours on McMaster, Grainger, and elsewhere; I was unable to find a wheel, handwheel, caster, or round delrin that met my requirements. I needed a strong disk that would fit on a 7/8" shaft that was no more than 5/8" thick (width of my bows limbs). <br />
<br />
Until I had a eureka moment! Barbell plates! Something with a 6" diameter or bigger was perfect to clear my cams.<br />

<b>3/31/2015 - Updates made in the Firmware and Inkscape plugin section below. Thanks go to Turnkey Tyranny for the many improvements and fixes he's contributed. </b><br />
<br />
<b><i>Also, I would like to note, there are many variations on the Laser supplies. Please be very aware whether yours is an ACTIVE LOW or ACTIVE HIGH enable signal. The firmware below is ACTIVE LOW.</i></b><br />
<b><i><br /></i></b>
<br />
<h2>
<b>Introduction:</b></h2>
<br />
I've wanted to start playing with Laser Cutter/Engravers for quite a while. I finally happened across a great deal on a <a href="https://www.amazon.com/gp/product/B012F0LKHE/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=diyengineerin-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B012F0LKHE&linkId=ff31a75dea5cbf646c924271dfe282bb">Chinese made 40 watt Laser Engraver </a>with the Moshidraw software and control hardware. Wanting something I can modify and that is of better quality I decided to use my spare RAMPS 1.4 and Arduino Mega I had sitting around. I've successfully upgraded the system and here are the details so that others won't have such a hard time getting theirs up and running. One benefit with this setup is the system is completely standalone. All you need is an SD card with your gcode files on it (remember to have the .g extension)<br />
<br />
Please excuse the picture quality, when I get some time I'll try to take better ones.<br />

The aquarium water pump it came with actually works fairly decent, some heat exchangers help dissipate the heat due to my small reservoir of distilled water, the clamp is there because I don't have a check valve and air would get sucked back into the lines. The 12V fan is being driven from an ac wall adapter for now until I put a 24V to 12V DC converter in the laser to power it all:</div>

<div class="separator" style="clear: both; text-align: left;">
- G00 move laser to position without turning off</div>
<div class="separator" style="clear: both; text-align: left;">
- G01, 02, 03 etc.. are cut moves</div>
<div class="separator" style="clear: both; text-align: left;">
- S(0-100) specifies the laser intensity on G01,02,03 line and arc moves</div>
<div class="separator" style="clear: both; text-align: left;">
- G07 is RASTER line. </div>
<div class="separator" style="clear: both; text-align: left;">
- Check the direction of the fan mounted inside. Mine was blowing out... Blowing in is much better and smells better too. </div>

I've decided to make a more streamlined version of my previous 3D DLP Printer. After finding a good deal on 8020 for some 2" square aluminum extrusions, I decided to go ahead and start the build. </div>

Below, I've mounted my linear rail (14" of travel) to two 36" long 2" square 10 series t-slot extrusions. I used some 8020 right angle gussets to make it very rigid. </div>

I used a 1" square t-slot extrusion to mount the first surface mirror and another to mount the projector. I plan on designing a better projector mount to print on my reprap soon - I'll post pics of that once complete. Just a right angle piece of aluminum holding it on at the moment.<br />

I used the original mount for the mirror I had made with epoxy and my mitre saw. I plan on printing a more "elegant" solution once the DLP printer is up and running. <br />

I mounted a 2" extrusion accross horizontally and used 1" extrusions to frame out the vat base. It is cantilevered out from the vertical members and is very rigid. The paper is there to adjust focus and measure the x y values for the print area.<br />

Now, I've mounted the peristaltic pump on the vertical member. The DC motor can operate in both directions allowing me to fill and drain the vat. I have still yet to design the "nozzle" for the portion that lays in the vat. <br />

The birdcage blower fan is mounted to the vertical member along the back. I will be cutting acrylic pieces to enclose the VAT to the top of the linear rail. The blower will be connected to the top and blow into a activated carbon filter. <br />

Here you can see the blower fan better. I've also mounted the build plate to the linear rail. Notice this design doesn't have a slide mechanism. Previously I had the VAT mounted on rails and it would slide between lifts. For this design, I plan on making various attachments to the Z axis. One will rotate a circular build plate, another will be as shown below, and yet another will have the slide mechanism on the horizontal bar coming out of the Z axis slide mount. <br />

Finally has some time last night to finish the build. I'll post those pics soon. Here's half of the rook I printed so that the interior is visible. This is the first test print and it came out excellent. Has some fuzz from my pocket (brought it to work to take pics). </div>

I finally got around to taking some pictures of my 3D DLP Printer build. I would like to give many thanks to Tristram Budel for his Instructables article detailing a DLP printer build. This article was used as a great starting point for me. It is full of information, and is a recommended read (<a href="http://www.instructables.com/id/DIY-high-resolution-3D-DLP-printer-3D-printer/">http://www.instructables.com/id/DIY-high-resolution-3D-DLP-printer-3D-printer/</a>)<br />

These two photos are the overall of the build with the panels removed. The panels are needed so the exhaust fan and pull the resin vapors out of the house without letting any escape. The Bucktown polymer's resin I am currently using (which is VERY high strength once cured) has flammable vapors. I'm working on a carbon air filter with a stronger blower fan for something that doesn't need to be piped to the outside.<br />
<br />
Some Videos: (the fluorescent lights do not cure the resin, I can keep them on all day long without issue.)<br />

I used 1" T-slot aluminum to create a "box". I have the Y-axis vat slide on two linear rods with bearings. There is a single NEMA 17 stepper that pulls the vat parallel to the Y-axis. While the Z is lifting, this Y axis motion helps counter any suction forces encountered. I have printed relatively large prints, and this was very successful. No tilting or twisting needed.<br />
<br />
The Z-axis is a linear ball screw stage I got off e-bay. It has 14" of travel. There is a NEMA 23 stepper attached to this axis. The whole thing is controlled by an Arduino Mega paired with a RAMPS 1.4 board with Pololu stepper drivers. An ATX supply provides the power.<br />

The build plate is a simple cut piece of aluminum. 104mm x 204mm. I sanded with a 120 grit sand paper and cleaned it. The prints stick to this very well.<br />

The 5/8" linear rods and bearings support the vat and Y-stage. I used some more T-slot aluminum and REPRAP printed brackets to secure it all together.<br />

Here is the side view. My 1080p DLP projector (Acer H6510BD DLP) and a single surface mirror I got off ebay. No modifications were made to the projector, I didn't remove the color wheel or anything. I cut some acrylic to make a 45 degree angle and epoxied an adjustable mount. I can adjust the distance to I can achieve higher resolution prints that are smaller, or larger lower resolution prints for big objects. Still playing with the cure times to get the build times lower. <br />

Here is the back with the NEMA 17 stepper for the Y axis. It has a simple threaded rod. There is no need for high accuracy on the Y axis. It's simply used to help detach the printed layer with a lateral force. I have found 5mm of deflection for the complete Z axis cycle is enough.<br />

Here is one of my VATs that needs to be recoated. I used a 300mm x 300mm borosilicate glass (<a href="https://www.lulzbot.com/products/borosilicate-glass-bed-300mm-x300mm">https://www.lulzbot.com/products/borosilicate-glass-bed-300mm-x300mm</a>) with aluminum for the walls. Black silicone to stick it all together, and Sylgard 184 for the coating. The borosilicate glass is "VERY" strong. I doesn't deflect at all with a fully exposed 104mmx200mm print. The Z axis speed has to be reduced, but they seperate with 0 missed steps...<br />

Here is the peristaltic pump I got off e-bay to get the resin out of the VAT. It works great, just learned the hard way that you need to flush it with isopropyl alcohol after each use....<br />

Here are some prints I did of a compound bow stabilizer and sight mount I designed for the Hoyt Carbon Matrix: The stabilizer was a large print, I had to make sure the Z axis was almost perfectly perpendicular to the VAT.<br />

This is an AR-15 Quad Rail. This was an extreme test of the full 14" travel. The only issue was the "bleed through" of layers, I need to add more graphite powder to the resin to prevent this. <br />

<b>ADDITIONAL FINDINGS SUMMARIZED FROM COMMENTS/EMAILS and GENERAL QUESTIONS I'VE HAD SINCE HACKADAY POSTED A LINK TO MY BLOG:</b><br />
<br />
** Z-stage - "THOMSON LINEAR MOTION 2RBM120DMHL QUICKSLIDE 14-3/8"
TRAVEL" The pitch is large, which surprised me that 100 micron layers
are no problem for it. The ballscrew has no measurable backlash,
atleast not with my budget calipers. I've tried down to 50 micron
without issue. I would need to do some more experiments to see what
it's capable of. I'm using 1/16 microstepping on the stepper drivers
with a big NEMA 23 stepper on this axis. <br />
<br />
When I get some time
I'll try some experiments to see what layer thickness I'm able to get
reliably. The 1080p projector is a dream for X, Y. <br />
<br />
** I
chose this projector simply because it was tried and tested with the
instructable article by Tristram. The amount of UV that comes out of it
without a single modification is wonderful.<br />
<br />
** Bucktown polymer ZVE500-V420 UV resin:<br />
12 second initial layers (5 layers)<br />
5.25 seconds per 100micron layer <br />
Some prints with overhang geometries need some graphite powder added to prevent bleedthough from layer to layer. <br />
<br />
** Makerjuice SubG+ resins.<br />
First 5 layers - 13 seconds<br />
Each 100micron layer - 6.25 seconds<br />
<br />

I finally got a CNC Router. This one is one of the low cost Chinese CNC Routers. It's a great machine for the price.<br />
<br />
The first problem I had with it though was the CNC Controller being Parallel port. I could've sworn I had a PC laying around that had Windows XP and a Parallel port, but I was wrong. Wanting to get this Router up and running I decided to look into a USB to Parallel bridge via an <a href="https://www.amazon.com/gp/product/B008GRTSV6/ref=as_li_tl?ie=UTF8&tag=diyengineerin-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B008GRTSV6&linkId=db28a027ceac26650a522fd4a5e5ea35" target="_blank">Arduino UNO</a> I had laying around.<br />
<br />
After doing some research I came accross GRBL (https://github.com/grbl/grbl). This opensource firmware for the Arduino will take G code via USB Serial and output the corresponding step/direction signals to a Stepper controller.<br />
<br />
I had a female parallel port connector in a bin and straightened out pins 2-7 and just inserted them into the arduino digital pins 2-7. I then connected Pin 25 to GND on the Arduino.<br />
