Title: 3-axis cnc conversion of Proxxon Micro Mill MF-70
Post by: pline on October 30, 2014, 04:46:54 PM
Hello, I have a Proxxon MF70 micro milling machine that i would like to convert to cnc and use it with Mach3.
i have done a little research online, and although am a little skeptical about using a TB6560 based stepper driver boards, yet am not sure who or where in India can I source these boards from. I am really not comfortable importing these from China.
Can any kind soul direct me from whom or where to source the following i. 3 X NEMA23 stepper motors ii. 3 X stepper motor driver boards iii. 1 X suitable interface board for Mach3 iv 1 X Power supply unit
Thanks in advance Regards Nilanjan Paul

Completed the CNC control box. Now to couple the stepper motors to the mill. Have procured 3 Lovejoy couplers, but would have been better if could get hold of 3 oldham couplers. Will turn the couplers and drill the shaft holes next. Regards Nilanjan Paul

yes the couplers are aluminium o/d 25mm and 50mm long with rubber cushions. will machine both ends, prior to drilling the holes. Yes I would use limit switches 1 each per axis to define +, - and home limits. I have kept using the coolant/mist mist controls optional for the future. Regards Nilanjan Paul
