Hehehehe
Fun with lasers
Hooked up independent 12v in, and PC9 plus ground PWM. Temporary harness
From the tablet- in Terminal
Ran M3 I
Orange led popped on. Good sign
Took a few minutes to get it running but that’s only because I forgot about the safeties. Marlin only sends the laser PWM on G1 moves
So- set up a little 2.8mm thick piece of balsa and types in
G1 X25 F240 S250 and hit go
Single pass at 4mm/sec, 99 % ish power .
I was getting some reverberations in the module, due to the slow speed and the cantilever. Very regular periodicity.
That went away when I pushed speed up to 5mm/s. That’s fine, since I’ll be doing cutting of 1/4” at 6mm/s with 2 passes for a nicer cut
So happy right now, lol. Such an easy addition.
