My resolution is calculated as 200 steps per turn. 10mm for turn.
10/200=.05mm/step

If you want me to increase the steps per rev by 10, the calc would look like this
1/200=.005mm/step.

The critical speed for the 16mm screws 1200mm long, fixed at one end and supported at the other is 1249RPM.

My screws are fixed on one end and supported on the other. Does that change things?

Maybe my calcs are incorrect for my motor corner speed.
191xV/(current x inductance)
=
191x48/(3.5/2.8)=935.51

That's not the speed my motor will turn, I don't fully understand it, but I...

Thanks for the reply hanermo, is there any chance you would be able to explain?
Are you suggesting I should be going for a 1605 screw?
The cutting force is a product of the cutting depth? So if I...

Hi Everybody, I've been on this thread a few times, this might actually be my first post, I can't really remember. Anyway, I've been working on a CNC mill/router design over the last year or so, and...

OK, back to the drawing board then.
I was going to use the 6560 boards because of the price, but maybe I can reduce the motor size to offset the price of using the DQ542MA stepper drivers?
I was...

Hi,

Im fairly new to the DIY CNC scene. I've been researching for a while, but still very much a noob.
