Motor tuning setup - Need help
« on: February 13, 2016, 02:38:39 PM »
Hi All

I have a DM542A driver and nema 23 425oz.

I need to put the right parameters in mach3, motor tuning.

I am not sure which settings that are the best. For this setup

Can anyone help on the track, thanks.

I have collected some information about the equipment.

Can someone help to put all this together.


Nema 23 425oz
Step angel 1.8"
Current 3A
Shaft 8mm

DM542A
SW 1, 2, 3 on, on, off
4 off
SW 5, 6, 7, 8
Can be
400, 800, 1600, 3200 and so on....
I don't know which one to choose

Trapez 12mm
Pitch 3mm from top to top

But how do I calculate all this information correct.

So it fit in mach3?

Am I still missing something

Step angle 1.8 = 200 pulses per revolution
Set the switches for 2000 micro stepping
3mm pitch screw

2000 / 3 = 666.66666666666666 steps per unit (mm)

Thanks for your reply...

I was getting 533 or 1066, so something may I have done wrong.

Now I will take a closer look at your post.
