Hi ,I have recently finished converting a Sieg X3 to cnc, everything appears to run fine untill my latest job .I'm maching six triangular cut-outs around a cast iron disk, to form spokes for a flywheel.  The programs runs fine,but  after reading the M30 and returning to the begining of the program the DRO Z and sometimes the Y changes value.  e.g. The Z was returned to 3" correctly, but DRo changed to .58??  it does this constantly but random values. I'm lost with this one,so any help appreciated.
