Did you end up getting this sorted out? Im running an almost identical setup and might be able to shed some light on settings

It is always good to post what you have done, even if it is a different setup there will be someone that it will help or give them and idea of where / how to start

nope, just got confused.
Just wanna know how to set the servo up with mach 3, ess, and the dmm breakout board. I'm using a 2:1 gear ratio running dyn4 drives at 240v, so i'll be getting 6000 rpm. I want to be able to run the servo with mach 3 using m3 s#### codes
I was hoping for a really simple explanation of what I needed to do to get it working right.

USMarine, I have a similar setup and will be doing the same thing soon. I did some research to ensure that I'll be able to rigid tap, and get the full value from the Servo spindle. The best method that I have found is not to use the typical SwapAxis method, but rather simply using BOTH the Spindle step/dir pins and the A-axis step/dir pins both set to the same output ports/pins in Mach3. The wiring will be just as you did XYZ with step/dir wires feeding from your BOB to the DMM driver's pins 11 & 22 (5V) and pins 10 and 23 (output pins from your BOB) . When you need to tap, you'll use A axis G-code.There is a video on Youtube demonstrating this method, and it appears to work well.

There may be better methods, but this is the best I've stumbled across and what I plan to use once I have time to finish up the servo spindle motor mounts, etc. Chime back if you find a better method, many of us would appreciate the guidance.

Here's what I got so far for mounting servo Attachment 433040

tried rotating pic but when I posted its sideways again
Apologies for for any neck pain that may occur

What is you Timing Pulley Ratio

[usmarine21m]

I put what is in what I just posted. 5mm gt2 timing pulley, 60 teeth for the one connected to the servo motor, 30 teeth for the one on spindle

Ok so the way you have it that is 1:2 one rotation of the motor moves the spindle two rotations

So I plug in the cable from the dyn4 drive into A axis on the breakout board?
From what I understand on page 9 http://www.dmm-tech.com/Files/DMB425...tVer010106.pdf
A axis dir is pin 8 and A axis stp is pin 9?
So I go to configure ports and pins in mach 3 and say spindle is those ports and pins and also A axis?
Is there anything else I need to do to have mach 3 be able to start and run spindle with m3 s#### command?
Have you figured out what needs to be done in the Dyn4 drive tuning software? The gear # and other settings?

Thanks for your informative post

Not the same servo but similar set up. Did you find a way to control the spindle with m3sxxx command? I see many tips with its easy use step/dir but no one thst shows free pics and give a full answer to understand how to do you actually control this servo spindle... The more I read, the more I get confused. :-(
