VoidMicro Engraver-O Field Upgrades!
Description
Laser Engraver Field Upgrades! Expanded Area Upgrade! Air Assist Upgrade! Laser Height Upgrade! I recently acquired a cheap laser off of Ebay. The listing didn't provide details, but it turned out i was purchasing a VoidMicro Engraver-O (LC2429O) which is fine. I got what was in the pictures, and after a day or two of finagling, I figured out how to use it properly. HOWEVER, this laser was designed really inefficiently! I didnt take pictures before the change, but it's original design is well documented on their website (http://voidmicro.com/Manual/OMachine-en.html?page=page_Manual) I tried to use as much of the original screws and stuff as i could, but some additional screws will be required. Specifically M10 and M3 Screws and Nuts. If something looks similar in how it mounts to the original hardware, that's because it is. this should be intuitive ISSUE ADDRESSED 1 OF 3, The manufacturer claims a print area of 240mm x 290mm. (I don't think I was getting even that!), but more could be squeezed out with alternate parts The issue is with the wheels that are mounted to the Y-Axis and carry the X-Axis. They are mounted horizontally, and that takes away almost 2 inches (51mm) from X-Axis maneuverability. In the same stroke of inefficiency, the X-Axis rail is mounted directly center of those 4 wheels which in turn, chops off some length from the Y-Axis as well. My redesign completely replaces the acrylic mounts for the motors, as well, offsets the position of the x-axis rail. This design also relies on the height slider included on this page to hit the y-axis homing button. CONFIRMED FUNCTIONAL DIMENSIONS: 324mm x 272mm VERY IMPORTANT FOR THIS ATTATCHMENT! You need to swap the positions of the timing belts on both sides of the machine. The way the manufactures instructs you build this, is made for the wheels to be positioned Horizontally, Left to Right, But you are going to need to take apart and change the belt to Vertical, Up to Down. You will need a 6-10mm M3 screw ISSUE ADDRESSED 2 OF 3 There was no HEIGHT ADJUSTMENT for the laser. things have to be placed underneath, or the engraver has to be raised to burn just about anything! Screw that! I originally had a single screw from the top, plus a spring, plus linear bearings, plus a mount for both the laser and carriage that cobbled all this together and it worked pretty great! but it ate away 32mm from the Y-Axis maneuverability. unacceptable, and really cumbersome for someone on thingiverse to download and source all the additional parts. So I made it simpler! Its pretty much just two sliding pieces of plastic with the means to tighten them together at the desired height. Just look at the pictures, idk, you'll get it. for this one you need to have TWO #10-24 3/4 MACHINE SCREWS and TWO #10 NUTS. Check your local Harbor Freight. optional, but you can also insert a 6mm M3 SOCKET HEAD CAP into the carriage side, and the bulky head will insert into a slot on the laser side, and this will provide an additional layer of stability. ISSUE ADDRESSED 3 OF 3 And finally, there was no air assist! For this one I just took a long look at the laser, placed a 50mm blower fan on it at different points until i found a spot that looked easy to work from. its just a funnel that goes down the the height of the laser lens, then a second piece attaches to the lens itself and funnels the air directly at the focal point. I'm not an airflow engineer. I'm sure someone could get a more efficient design with the same blower fan i used, but this IS doing SOMETHING and I keep it activated. For this attachment, you will need: 24mm M3 screw, head type does not matter Wire, pull it from the motherboard, along the length of all of the braided cables, all the way to the laser, then give yourself another 2 inches. that's how long you want it. Soldering skills and tools Look at the included pictures for instructions on how to power the fan. When someone comes across this in 3 years, let me know what you think!
