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?
