A newbie builder here but with plenty of electronics experience. I made my first laser controller by putting together an Arduino and a grbl...
PLA starts warping at temperatures as low as 40 deg C. It has mechanical rigidity but not the strength. The first version I had built was with PLA...
Got it! I'll read up more on this. Thanks.
This sounds awesome. I'll be sure to keep track of this. And thanks for the suggestions on improving resolution. Since my specific purpose was to...
Yes you could do that but I don't see any purpose to that other than aligning the Y-axis extrusions edge-to-corner with the 2040 slots. The V-slot...
Thanks! I paid about $300 for the whole build including the laser. I also built a small enclosure to house the whole thing and that was extra but...
The laser is about 1.6W. I have cut 3mm acrylic from this but with multiple passes. The tree design that is shown in the build was cut from a 2mm...
An SMD stencil on vinyl. The component pitch seen here is 0.8mm.
Thanks! Would the leadscrew mechanism improve any of the resolution? With this one I can't seem to go below 0.65mm pitch components. I have been...
HPB published a new build: A simple low-cost XY plane laser engraver/cutter inspired by the Much 4 laser build, with minimal parts and assembly...
Yes those are 3D printed. They have tapered slopes on the outside. As you tighten the screw you snug the wheel more on the rails. This means that...
Got it! Thanks Ronald. I think I'm going to replace the plastic spacers with aluminium ones.
I'm finally taking up building the D-Bot 3D printer. I was going through the excellent build guide and some of the parts listed in there. I...
Ok. Let me try this. Thanks. Do the max travel default settings make any difference in the homing cycle? One time, homing did work. The axes moved...
Hi, any more insights on this issue?
Oh I never thought of that. I've built a laser cutter with just the X and Y axis. I have not altered config.h yet. So would it work if I change...
OK new issue: Homing does not work. I've wired 4 limit switches (2 on either side of X and Y axes). Both the X axis switches are connected to pins...
Weird but I just reset grbl and it works as expected now. Thanks for trying to troubleshoot this!
