I am building yet another cnc router this time I would like to get the motor sizes right . I’m building all steel machine this time. It will using two motors to drive the gantry. One on ether side of the machine. The gantry with the spindle attached weighs about 40lbs. This is going to be a 18X36 machine. I would like to get about 300 I.p.m. rapids. I plan on using acme threaded rod. I will most likely use 3/8 rod 8 threads per inch 4 start. I will most likely buy my motors and drives from Keling.
If anyone could give me a suggestion as to what size motors to use with this axis I would appreciate it.
