Thread: Nema34 - DM860A Driver & Mach3

Hello to all,
Last year I bought a cnc project with a wooden frame.
(I do not know if I can paste the site link here).
At the moment I have assembled the whole structure with the engines too, but I have some difficulty in configuring them.
The engines are:
- 2 Nema 34 1232oz.in 5.6A 4 leads (X axis & Y axis)
- 1 Nema 23 425oz.in 3.0A (Z axis)
The drivers are DM860A, one per engine.
- 3 Power supplies 350Watts (60VDC / 5.83A)
- 1 Breakout Board DB25-1205
Mach3 management program.
First Question:
On these engines it is not specified if the power supply is Peak or RMS, so at the moment the dip switches for the Nema 34 are set to OFF OFF OFF >> 7.8A Peak / 5.6A RMS is right? Or do I have to set them ON ON OFF >> 5.7A Peak /4.0A RMS?
Second question:
From my information the engines have the following technical specifications:
- 200 steps
- 256 microsteps
So if I do 200 * 256 = 51200 it should be the maximum resolution that these engines support and it is also a value that I can set by dip switches on the drivers.
In this configuration, however, the machine is moving very slowly even if objectively with this setting I have not changed speed and acceleration
Based on your experience, what values should I set on the dip switches?
Besides I can not find the right parameters for the motor tuning section of Mach3, is there a way to calculate it (including speed and acceleration) or do I have to use the "auto-calibration" tool once the dip switches have been set?
If you need more information (for example pulleys - motor ratio), tell me.
For a better understanding I am attaching some photos of the work (now it is completely assembled and wired but I have no more recent photos)
I thank all those who can help me in advance.
