I bought the decoder cable from centroid an few months ago. The wire they sell by the foot. The problem I see right now is that the pig tail comes out of the encoder to a cannon plug. Then the longer wire that runs into the cabinet has the other cannon plug end on it and then my soldered 9 pin connector. Im not really sure I wanna be opening up this decoder to desolder and solder on a new wire lead. Im guessing the decoder when new was over 500$
I gues I really dont have a choice.

Encoder not decoder😁
The cable you got from Centroid is the correct cable.
The factory encoder cable should have been ok. Did you solder the drain wire to the connector shell?

Yes I soldered it. Would oil and a stuff cable cause the factory cable it to go bad? The cable is from 1998. Is there anyway to check it it? I have the cable routed way out of the way of anything trying to isolate the issue as well.

I'll be honest. I'd replace the encoder with a new 1000 line encoder. That way I know there are no issues with it.
I assume the encoder is as old as the machine?

Yes. The machine is a 98 model.

Any suggestions for the application? I need one good to 8k rpms with a shaft

I would check with Heidenhain and see if that model was still available.

Can you post a fresh report so we can get a look at your logs?
If there is good wire coming out of the encoder, you could splice the new cable onto the encoder cable shrink tube.

I'll post a new report sometime today. I need to finish making some parts then run the wizard to add the encoder back and get it to fault.

I ran the machine today with and without the encoder hooked up and I didnt get a fault. The encoder was hooked up when I was cutting. The air cut program was about 30 mins or so I it ran with not faults. I ran it three times I think. Heres a fresh report. I was getting alot of spindle faults on Sept 5th. This is when I was having issues.
