Chasing an Axis Differential Error (CNCSNW?)
Posted: Tue Nov 09, 2021 11:08 am
For the benefit of everyone, hoping Marc Leonard with CNCSNW will chime in and describe how he would chase down a "412 Z axis(3) encoder differential error" on an axis.
An old client of mine has a large router (48"x48" which is used to cut ICE Sculptures. I upgraded the control to an All in One DC a little over two years ago.
Pictures of the machine can be seen here: https://photos.app.goo.gl/TvGPjTTTQT8ezUag9
Recently, he started getting a "412 Z axis(3) encoder differential error" intermittently. He would reset the control and continue on with the job. Starting to get a bit more frequent. He reached out to Centroid and they sold him a new replacement NEMA 34 DC Brush Servo. (Centroid/Glentek) to replace the old NEMA 34 DC Brush Servo (I believe it is a Redcom) So we are starting with replacing it today.
(Pictures and report attached)
The machine is obviously in a Freezer (no fun to work on) and the control is outside the freezer. So the cables from the machine to the control are fairly long.
I'd like to know (as do we all) the logical approach to chasing down the 412 Axis encoder differential error"
I was thinking its the encoder on the motor, but it could possibly be the cable, so I am taking one to swap in temporarily if needed.
Thanks in advance
Marty
