Machine: K40. Originally had M3 Nano. Now using lightburn
Board: The newest laser board.
Problem/ Question: The unit has been working fine for the couple of month’s I’ve had it installed. I also have a rotary installed using the “A” axis. I leave it plugged in all the time and it’s left under the unit when not in use. I switch on the rotary by using the lightburn software.
I just engraved 2 glasses. First use of the laser today. I noticed the ease that the carriage moved in the y axis while setting the glass in place. Now I have switched off the rotary and there is no y axis movement. No homing front to back. Only movement left to right.
The rotary “button” is now off and I even hid it from the main page. I’m pretty sure the board is not putting out a signal to the stepper since there is no resistance to carriage movement.
What do I check next?
