UPgrading CNC 3 axes  24x36x5’’,

Hi, my cnc is a old china 12 years old. 3 motors nema 17, 3amp, 1.2nm, ballscrew, 3 stepdriver ms-2h057m,
breakout board 4axes mach3 usb motion controller, spindale 1500w water collant.
I did clean  the surface table, change the breakoutboard, I’D like to change the motor nema17 for nema23 to improve the machine. Is it a good idéal?, also change the stepdriver. There so much difference choice, i do not know which one to buy. I need to know what motor to buy, what stepdriver to buy and the reason why?
Thanks to everyone

General Mach Discussion / Z axis losing height

« on: March 28, 2017, 09:14:16 AM »

Hi, when i start the job a 3D toolpath ruff machining, it does the job well, after i restart the 3 d toolpath finishing machining, everything is ok but     the Z axis move over without touching the material at some place. The X and Y axis are ok. So my question is where is my problem. could it be the z axis motor is not proper configuration, could it be the stepdriver, could it be a mach3 problem. I Really thing i am loosing step in Zaxis.   Any suggestion......thks
