General Mach Discussion / Re: Conversion of Denford TRIAC milling to LPT
« on: September 07, 2015, 12:53:45 AM »
Hi Jim
   Last year I got hold of a old Triac CNC(all green) Mill. I am going to change it to Mach3,  but not sure to select the right stepper driver for it.  It is also bit difficult to find the right parts in  Melbourne as this CNC is much less popular or outdated. Few customized supplier asked a big bulk for anything you ask for. My plan is to spend less using the ebay local supplier parts.
 What you think will be the right move  :

i. Using the ebay driver (range upto 40V) and BOB with the existing motor. These stepper drivers allow 12V-48V (.2 to 5A) range. Will it be enough for the existing motors.
ii. Using new stepper motor with new ebay BOB and driver. What will be good . How about Nema 23 with 3N.m 4.2 A 0.9 ohm
iii. What could be best power supply , i got option of choosing 36v10A or 48V10A.

It would be great if you can send me the wiring diagram you used :  zhaque11@gmail.com
