Ive a pretty sound electrical/electronic background but i'm a little confused between the specs of 2 motors. One motor is rated 12v @ 80 amps, speed 4100 rpm The other motor (from the plate) says 24v 5100 rpm 4 amps 350w (?) The first motor was used for starting model aero engines, larger sized via a rubber coupling. So using the data on the plate, this motor would be rated at 960 watts.

Yesterday i ordered 2 sets of pulleys and 2 belts for the CNC, im going to try a 1:3 step up with 16mm wide steel braced belts and see what the speeds are like. Looking at my old machine, im hoping this will give me at least 90mm/sec but this was with the pretty basic electronics i used at the time controlled via the parallel port, hardware handshaking was the slow factor of that machine. The newby jomac - General
I spent some considerable time in building the base CNC machine, learning from mistakes i made with the first CNC i made. The motors are large frame NEMA 23's with enough torque to start an engine on a WWII bomber, i had missed steps issues with the first build on fast acceleration. The steppers can certainly handle their outputs stepped up to gain the speed, but the trade off is a reduction in tby jomac - General
Im pretty new to the 3D printing scene, so please be patient if my questions seem a little dumb. Im very familiar with the operation of CNC machines, having built a couple from scratch to mill PCB's and front panels. The CNC im almost finished building at the moment, i want to adapt so with a change of heads, i can use the same machine for 3D printing. However, one thing is puzzling me and that iby jomac - General
