I have a Shapeoko XXL with a J-Tech 7 Watt Laser
Laser appears to work just fine, I have done a few projects successfully. Question: When I hit the “FIRE LASER” button it works sometimes, others times not? Without this it is difficult to set the laser position. If I use my manual on/off it is high power setting & of course leaves a dot. I need to use it on low power.
The fire button just sends a couple GCode commands to turn on the laser, so there’s not much happening there. If you set the power a little higher does it stay on? I can’t think of any software reason that it wouldn’t be consistent.
I will try a higher setting. I think I have it at 4.5% now
