I have a S3XL with UGS sender and have multiple fixtures on the bed of the CNC for a particular part I’m making.
I’m hoping there’s an easy way to use the G54 to G59 to select which fixture is being and have the zero’s for each fixture preset.
Just send the command to switch coordinate systems. Make sure your gcode for the job you’re going to run uses the same coordinate system or doesn’t specify one. Many CAM programs set G54 by default, so be careful.
If you want to use the G56 fixture, send G56, set Z zero and go. You set your zeros the same way you normally would, just make sure you’ve activated the coordinate system you want.
I checked the post processor in Vcarve pro and it does not send any of the G54 to G59 commands at all. I can add a macro to UGS to switch it. Does Shapeoko use G54 by default?
GRBL does. Every time you power on or reset the machine, it’ll default to G54.
