vtcnc, no the 5v isn’t hooked up to the encoder cable per the drawing from DMM. That’s not the issue.

Problem 3, has been fixed. The counter balance took the load of lifting the mill head up and made it easier. No over current faults on the z axis drive. So one problem down now 2 to go.

I would build 1 DB25 connector per DMM drawings or inspect one you purchased from them? I can't find the drawing online from DMM for the JP4 port on the servo driver to Acorn? I have a copy in my notes, but I'm not home to scan you a copy. I used Drawing ACORN_rev4, DMM DYN4 SERVO DRIVE with great s...

Problem 1 : hasn't been fixed. Centroid error code 455 Spindle Axis (5) encoder quadrature error is still a issue. Is still don't knowing where to replace the PLC Code. I have a friend that is PLC code savvy hopefully he can install the fix. If not I may have to pay. (viewtopic.php?f=60&t=4981&a...

Marty, For clarification I didn't use the DMM software to tune the spindle. I only used it on the Y & X and gave up on it because it sounded bad. I went through the manual tuning email I got for DMM posted above. I still get a z axis fault out every so often, after homing at 30 IPM. Its weird, i...

Thanks for the response guys. Marty, yes I’ve have both ends of the shield wire connected to the DB9 connectors. The are connected, I checked with my meter. Low ohmic value was metered. I did check the forums and found what you suggested, buy encoder cable, connect shields to both ends, check contin...

Added information.

Hello, I need some help with my DMM servo I have installed as a spindle motor. To be fair I bought this servo a couple years ago thinking it would be a good spindle motor for this mill. Why I thought it would be good was the weight to HP ratio was good. As some may know the Chinese made 45 mills ten...

I think that’s the best for me also. I’m not sure what steps to take? I can install the latest version. I don’t know if there’s anything special I need to do to get my Pro license out of one version and into the new version. I’m tempted to just install the latest and see how it goes.

I’ve watch cnckeith’s videos but I’m caught in between an original install and update. I presently have CNC 4.18. installed with my Pro mill lic. I was following Marty’s setting up DMM Dyn4 4.18 only YouTube video. I noticed in the the Navigation folders on my installed CNC 12 4.18 does not have the...

Thanks for the quick response!
