Update on bench testing,
I used Kieth's cheat sheet and it all worked. There is a box that can be checked in DMM software that will put the servo enable active low. By doing this you can leave the enable box checked in advanced settings in Acorn Wizard. You must also power down the DYN4 for any changes to take place. My last and only issue is my servo only turns one direction when I change to 400khz. If I stay at 200khz it works great. I hardly have anything connected to Acorn so I can't see how I have noise grounding issues. Any advice would be greatly appreciated.

The ability to invert enable in DMMDRV is new.
I prefer to do it in CNC12

Your issue not able to use 400khz is a new one on me.
You are using DMM DYN4 to Acorn cables?

[marks3465]

Yes using DMM cables, the servo moves perfectly 1 direction. Only the DRO shows movement X- direction.

[martyscncgarage]

I'm at a loss. So your DRO is changing but no motor movement?

[marks3465]

Yes, it doesn't make any sense to me either. Stephen from DMM is going to look at it today. I'll post what he finds out.

Update: I wish I had good news but still can't use 400khz pulse rate. DMM has a feeling that Ver.4 Acorn has an issue with DYN4. I'm going to try a older version of Acorn. Has anybody else had any issues using Ver.4 Acorn with DMM DYN4?

[martyscncgarage]

Can you provided a picture of your control cabinet and wiring?
Running Version 4 Acorn hardware @ 400khz with DYN4 no issues

[marks3465]

All I'm doing is bench testing at this point. I only have one drive connected.

[martyscncgarage]

Did you try the other drive? Try on a different axis?

[marks3465]

Yes, I have tried everything. That's why there is a another cable attached to Y axis. Same thing Y+ works but Y- doesn't. The DRO shows movement but the servo doesn't move. The drive in this picture is a different one from the one I started with. Also tried new DB25 cable.
