I’m not sure if this is a hardware or a software issue, I’ll let you all decide.
Lightburn was working great about two weeks ago. I got a new laser (LaserTree K20 Pro) to replace a Chinese POS that was a scam on Amazon (different topic). After receiving the laser and installing it, I fired up Lightburn, slapped together a quick test file (simple square 320mm X 320mm), zero’d everything out and hit go. Immediately, my machine tried to go the opposite direction. This has never done this before.
Here is what I have done to troubleshoot.
I first ensured nothing was out of bounds. Next I made sure the start point was bottom left and it was set to user origin. - no love, same thing. All steps from here on are with the laser disconnected.
Using the X & Y axis move control, I moved the laser to 100x, 100y and started again. The machine tried to move negative Y axis beyond limits.
I then moved the machine to 320x, 320y to see if it was moving inverse - nope, the machine moved negative y past 0 and hit the limits.
Using the X & Y axis control I can move to specific places correctly, BUT, when I use the “move to coordinate” function, it moves negative Y axis to the limits and beyond. Even sitting at 0,0, when I give the move to 0,0 command, it moves negative Y axis beyond limits.
Attached is the grbl settings and my “move” console.
