Ok, next problem. The Z is a two position air cylinder, where I use M64 / M65 to lift and lower. That seems to be generating the error "Cannot set auxiliary digital output with cutter radius compensation on".
Is there any way around this. Do I have to turn radius compensation off before each head lift / drop.
