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

Re: X Axis problems Hardinge Lathe
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

Re: X Axis problems Hardinge Lathe
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?

Re: X Axis problems Hardinge Lathe
Hello, that board should still be within the warranty period of 12 months.

Re: X Axis problems Hardinge Lathe
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
