Hi! I am looking for help with my Jinsoku LC-40 rotary. I have it set up and configured correctly, I believe. The rotary turns in the “test” mode, but then when I “run” the program, the laser only moves on the X and the rotary doesn’t turn. Any suggestions? Thanks!!!

I assume that’s only a small portion of the gcode. There’s not a lot of Y movement but definitely some in the listed gcode. If you’re not seeing Y movement check that the material is not slipping on the rotary.
The Y axis speed is 600 mm/min. Is that too fast for the rotary?
IDK! Do you have a suggestion?
My rule of thumb is to reduce speeds by a factor of four, but with a rotary maybe a factor of ten is in order.
Make a backup of your current settings.
Then reduce the maximum Y axis speed (GRBL parameter $111) to maybe 60 mm/min.
If that changes things for the better, than you can try various speeds between those limits.
Then you make a backup of those settings.
Thereafter, you can flip between XY and XR operation by loading the appropriate settings file.
It will be nice if you describe your setup. Is the rotary connected as Y-axis or does it have an extra stepper driver (and axis)?
Just saying ‘it doesn’t work’ and posting some gcode does not help very much.
