Sorry to be a bother, but the MPCNC is a brilliant idea so I’m trying to adapt it for a particular purpose.
Currently I’m trying to go beyond engraving and get to a point where cutting 1/8in acrylic and MDF would be possible in a few passes with some accuracy, maybe even less dense wood too.
I wasn’t sure the 2.8W laser in the guide would quiet manage that, but I love the idea of something that just needs a heatsink rather than water cooling and a big power supply.
If I were substitute in this laser and driver board would it work?
6W laser and lens also from DTR like the MPCNC guide
Laser Driver for 12V and 5A at 3.5W and TTL
Would I need a different resistor? Would going higher power lose accuracy while still not reaching the 1/8in mark?
I’m expanding over from the 3D printing realm and really have marginal electrical and laser knowledge. Outside of the swap of the laser itself I was planning to expand the frame and add an enclosure with active cooling to try to keep down charring. I’ll run that off another PSU though so I can try to stick with the simple 12V5A power supply.
I have plans to build a mill version as well, but before I start running around ordering parts from the shop and amazon I was curious to know if I’m asking too much of the design.
tl;dr Is there hope to cut 1/8in material? Will this 6W laser and board be of help or fail in a possibly literal flaming wreck?
