Does anyone know what the gear ratios are for the PM-45M or PM-45-CNC? My RPMs do not match up with Mach3 and my RPM gage. I have about a 300 RPM difference at high speeds and they start out about 50 RPM different at low speeds. If I knew what the gear rations were, I could set them in Mach3. I really don't want to tear the head apart to find out what the gear ratios are. The Chinese instructions aren't the best. Any help would be appreciated! Thanks, Butchss33
