Need help figuring this out

Last job I did ran completely flawless with no issues. Loaded this file and it keeps going haywire off the guide lines on screen. ( https://youtu.be/BL0Z8bbgc8c?si=bMGzfabBvKav6hJ4 ) I intentionally have sort turned off so the issue happens early in the video on the second cut. I have thoroughly confirmed there is no binding on torch lead and belt tensions are efficient. Belt gears on servos are tight and look to have flat spots to eliminate slip on shafts.
I do have X and or Y axis overtempature alerts that pop up after running any file. An overtemp issue I have tagged @Andrew about on here before with no response. I have also confirmed it is not a file issue as I have tested with other known good working files and the issue remains. To me it seems like something is slipping somewhere and allowing the torch to go off the mark.

These symptoms fit almost perfectly.

" Several key indicators suggest a potential issue with the servo motor in your ArcDroid:

1. Inconsistent or Erratic Movement:

  • Stalling, jittering, or failure to maintain position: This suggests the servo isn’t smoothly and accurately executing the intended movements.
  • Jerky movements or delays in response time: The servo may be struggling to react quickly and precisely to commands.
  • Inaccurate positioning: If the arm doesn’t return to the correct “zero” position or consistently deviates from the intended cut path, the servo’s encoder may be faulty.

2. Overheating:

  • Motor is excessively hot to the touch: This can be a sign of overloading, excessive current draw, or cooling problems.
  • Increased heat generation: The servo may be working harder than necessary due to increased friction or internal issues.

3. Unusual Noises:

  • Grinding, clicking, or buzzing sounds: These noises can indicate mechanical wear, internal damage, or electrical interference within the servo."

Bottom belt servo feels very smooth when moving the arm manually but has given Y axis overtempature alerts. The top belt servo feels harder to move manulally, is louder and has inconsistant movement. As in while moving the arm to move the top belt pulley only back and forth I can feel the tension get stiffer then ease up and get stiffer again.

I fear my ArcDroid has a damaged servo, possibly two.
