Calibration doesnt last...?

Hey folks… ugh… im so frustrated.

We have a 60x90cm 80w C02 cutter. we know how to calibrate it. I get it dialed in, and its great. usually lasts a few weeks! recently, it hasnt been lasting at all, and now really its like it lasts 2 minutes at most.

i dont know why it keeps getting out of calibration

theres the screws on the axis bar that connects to the belts/pulleys and i tighten those…
but even with those tight, it still un calibrates. is there somewhere else to check?

What changes when it becomes uncalibrated?

What are the symptoms when it is uncalibrated?

Do those screws become loose when it is uncalibrated?

This test pattern helps identify mechanical problems:

Scale it to fit the platform and run it as fast as it will go in Line mode with optimizations turned off and power set to mark a sheet of cardboard.

Upload good photos of the result so we can look over your shoulder. Let us know if the machine is “calibrated” or “uncalibrated”.
