It looks like it was a limit switch issue. I removed my Y-axis way cover, and some chips and coolant got into the switch and were causing it to trip. I went ahead and used everyone's advice and removed the limitAll, and am just using the soft limits. Everything seems to be running as it should now ...

I think I’m starting to remember how I wired this machine years ago. My setup includes switches for the + and - travel limits. Should I connect the HomeAll feature to the three switches that trigger in the home position? Would the opposite ends of the travel switches then connect to the LimitAll ...

It was stopping at about the same place each time, but now it's more random. Now it won't even reach the starting position of the program. It will rapid for about 1-2" then fault. I guess I will go through each limit switch and its wires, and see if I can find a bad one.

ok , that means the switches are normally open. so that means when they are triggered they close the input. use a continuity meter to verify this.

for Normally Open switches you wire them in parallel not series as shown in the schematic i posted above.

review starting on page 59 https://www ...

do they open in the input when triggered or close the input when triggered?

wire them up as classic HomeAll.

(ignore the LimitAll as seen on this schematic.)

thanks for the updated report. the last entries are below.
you can see these yourself in the error log menu in the utility menu.

i see you are using homeall and limit all. how do you have them wired? photos please.

I would drag the LimitAll out of the Wizard input selection (make sure the soft ...

This is the program I was running when I started having issues.

Is it possible to post the fusion file?

This is how it is if I post from fusion

Here is a fresh report. Thanks for looking into this!

Uwe

Yeah, I switched it off when posting, and it didn't fix the offset having a different number. It still shows T2 H1.
