How to use
- Printer off. Lay the phone flat on the printer's base or frame and tap Zero here. That makes the frame the reference instead of your table.
- Put the phone flat in the middle of the glass, top edge pointing to the back of the printer.
- The bubble drifts to the high side. The highlighted knob is the one to adjust.
- Finish with the paper test at each point. The phone checks the bed against gravity, not against the nozzle.
