Title: Confirmation on motor tuning...
Post by: Adam_M on December 15, 2015, 12:10:17 PM

I'm replacing my Threaded Rod with a 5mm Ball Screw and just wanted to verify that I'm doing the math correctly for tuning the motor with a G540 and a stepper with 200 steps per rev.

200 x 10 = 2000

2000 / 5.08 = 393.70

Thanks,

Adam

Hi Adam,
 5.08 ?
That would be a .200" lead, not 5mm which would be 10000 per inch or as you say 393.7 per mm.

5mm lead would be:
10160 per inch
400 per mm

yeah, caught that 5.08 in another thread... hence my uncertainty.

The Ball Screw has a 5mm pitch (0.196850394 in) not 5mm in length, I think you understood that, I should have been clearer.

So, I think this is correct then?

200 (stepper) x 10 (microstepping) / 5mm (0.196850394) = 10160

Is that correct?

Any additional information you could share on the Velocity and Acceleration entry's to start with?
