Hi I am glad to here someone else took on a makino retrofit. you can see my mill on myspace
jeff35m_73068@yahoo.com. yes i retrofit this big mill, or still working on it lol. is your spindle motor dc? mine is, and the field has 22 ohms resistance. I hooked it up in series and put a large potentiometer parellel with the field it works but will not stop. the motors got fitted with encoder where the resolver was. look at my myspace. I am stuck getting the pull knob stuff to work. do u have any schematics? ttys jeff
