Alright. This is my first post. Let me preface this by saying that I do enjoy lightburn. I’m two weeks into my free trial.
I bought a cheap Chinese 30x40cm 5.5w “DIY” laser on amazon in Germany. It’s running on an Arduino nano with Grbl 1.1f.
I am by no means a professional and my experience with cnc is on a “fan” level at best. I have an MBA and an MA if that tells you anything. Not exactly an engineer. I know my limits.
So, here’s the issue I’m observing:
If I do not put Grbl in laser mode, the laser cuts fine at various power levels.
If I do put it in laser mode, it reaches flashlight brightness at best.
If I do not put it in laser mode, it will burn travel moves.
If i do, i can see the laser turn off during travel.
Clearly, the power of non laser mode with the non-illumination of travel moves would be the desirable outcome.
My settings are otherwise exactly as described in the tutorial videos and discussion board responses I’ve browsed.
My s level matches the grbl value on the machine. I tried setting it anywhere from 255 to 10k on both lightburn and through console on the machine.
I even managed to adjust the steps per mm to the point where the machine matches what I tell it to do in lightburn. I’ll admit the math was easy on that, but success is success. So I think I’m making progress here. This just has me stumped.
I hope it’s an easy fix. I wouldn’t mind feeling stupid even.
