Retrofit of Precix 5x10 CNC

Thanks PCW, always appreciate your help!

1) Here are my hal/ini files, let me know if you'd like to see anything else.

2) Yes, LinuxCNC enables the drives. AFAIK

It isnt' going to fix your problem, but your FERROR and MIN_FERROR are both much too large for your X axis servo. Probably should both be some fraction of an inch. (maybe 0.1 and 0.01)

An encoder fault won't necessarily cause a following error alarm during a run-away. For example on your X axis with the 5" ferror, if you command a 4" move and Linuxcnc does not detect any movement from the encoder, you now will have a run-away at the fastest speed your drive and motor can do, until it crashes.

Awesome, thanks Todd, ya, probably didn't fix that from when I was first setting it up.

It's definitely an encoder problem. With LinuxCNC open and drives not powered, if I manually push the Y axis I can see the DRO change. Same on Z, but not on X, so I am guessing my X encoder lost connection mid run. I am going through trying to check connections now.

Yes, much smaller following error limits should be used so even a small commanded
move will result in a following error if the encoder position does not "follow" the move,
this would likely have prevented your runaways

Do you think it may be an encoder cable seperating as it bends through the flexible raceway...have a look at my username.

Thanks PCW!

I will get those changed, but if the cable lost connection, then would anything have prevented that?
