AI Help

It seems like you are trying to use an LGX motor in place of an xyz motor in your 3D printer, but encountering issues. Double-check the wiring connections and compatibility with your printer's firmware. Ensure that the LGX motor is compatible with the driver and settings specified in your printer.cfg file. If the issue persists, you may need to adjust the motor settings or consult the manufacturer for further assistance.
