Can I use Y and a rotary axis instead of of X + rotary axis?

Hi,

I usually use X and A as the rotation axes.

So the chuck is in the same direction as my X axis.

But I have more room in the Y axis direction so I could use larger materials that way.

If I could select the Y and A axis for rotation it would work IMHO - but I can’t find any settings.
Is this possible somehow?

A axis orientation? What am I missing?

I have a laser mounted to a CNC router. I have a dedicated A axis rotary that is oriented along the Y axis (wrapping X). I’m trying to figure out how to set up Lightburn to work with it. If I choose A axis in the rotary setup and create gcode to send to the controller (GRBL), only the A axis moves. The gantry stays in place. Is there a setting in Lightburn to let it know that the A axis is aligned along the Y axis? As I mentioned, I’m not using the Y axis motor to turn the rotary. I have a dedic…

Change your scan angle from 00 degrees to 90 degrees. I get much better rotary results with this direction that I do with x axis.

That works - great !

I was looking for an option in the rotary setup dialog, did not expect to find something in the general setup
