I ran some tests on my stepper motors. The motors are rated for 2.5 amps for a rated max torque of 4.8kg/cm. My drivers are A4988 compatible 2amp max and I'm running them on their max amps with heatsink and a fan over top of that.
Well you know what. The max torque I get out of them is 2.69kg/cm. I'm not impressed.
Uncle_bob, you told me 2.5 amp motors with 2amps stepper drivers isn't a good idea. Should have listened.
Motors like these would have been better: [ultimachine.com] But I didn't know of the site at the time..
So there you have it people, buy lower amp, higher voltage motors, like good'ol uncle bob told us too :D
