X Axis problems Hardinge Lathe

[lavrgs]

I am retrofitting a Hardinge CHNC 4 with an ALLIN1DC. Things were going ok until a couple days ago when I started having problems with the X-axis; not sure I can call it oscillation but it will shudder as it tried to move and will error out with a couple different codes 410 & 411, as I recall. Activating MDI will also cause the problem. Most of my moves were via WMPG but the jog buttons exhibit the similar results.
I swapped the X and Z axes - power and encoder (Sumtak LHE-714-2000) and the cross slide (former X axis) still had problems. The carriage - former Z did not move after the swap. I had to clear the cross slide off the limit switch but in the end I just wanted to see if putting it back to original got the Z axis working, which it did. I did run the X axis on 12vdc and it ran smoothly... I did not spend enough time with the axes swapped so I will try again. But I am stumped.
I don't have a great action plan. I might try getting a new encoder. The lathe had a prior centroid retrofit so it has original servo motors and encoders that were part of that retrofit. Is there a replacement for the Sumtak encoder listed above? I believe it is 1/4 inch hollow shaft and it is located on the ball screw

UPDATE I swapped encoder on X and Z and still have a problem on X, the encoders are both OK. Troubleshooting servo, ballscrews and ways sounds like the next steps

Probably should have checked earlier but the X axis fuse was blown and the replacement blew as soon as I powered the board. I will need to start the process of returning the board. This was bought August 2023 what is the warranty period?

Hello, that board should still be within the warranty period of 12 months.

I've taken both X and Z motors to be checked out at a local shop that cncsnw has suggested. I expect that I will know next week if there are any issues found. The ALLIN1DC will be sent back for repairs
