When you turn the machine on and start up the software it doesn’t know where the Z axis is. So each time it turns on you need to lower the base with the Z Home button then raise it up with the calibration tool then calibrate the cutting table.
Does anyone know why this is?

I have done the usual checks of nothing being left in the machine its all clean. I’ve put a new battery in, just in case that has anything to do with it but still no luck in the machine remembering where the cutting table is.
