Hi again David,
I was able to start the tests. I thought this would be a piece of cake, but it wasn’t.
My first test was… well, see for yourself:
Doing a little research on the forum seems to be a common firmware problem. I made a modification to the “Marlin.cpp” file, following this thread:
https://forum.v1e.com/t/more-laser-advice-firmware/13389/42?u=roger181078
I do not know if this modification will negatively affect any aspect when my machine does not work with the laser, but well, now the result is quite better.
The software I use is “Image2Gcode”.
Any suggestions are welcome. Add that my machine is an LR2, with this firmware. My electronics is Ramps, and I use pin 44 with the M106 and M107 commands to control the laser.
Regards
Roger
