Hello all,
I am just about to get my cnc router up and running for the first time. It has been a long process of building it. I have a questions about my feed speed, and I will start with giving you some general specs on my set up.
I have a 200 step per revolution motor with 150 oz inches. I directly couple them to my precision acme thread using a spider coupler (LoveJoy). The acme screw is a 0.5"-10 screw (10 turns per inch). And I am driving my motors with a home built stepper motor controller, which is using half-stepping. I connect everything to Mach3 to run it.
that being said I believe that I should have 4000 steps per inch of travel. When I test everything out it runs fine at around 10 inches per minute. But this seems very slow compared to what I am reading about cutting speed.
Am I doing something wrong? Have I picked parts which were poor choices for a first time cnc router? any advice is appreciated.
Josh
