Direct from factory, the K1 Max bed level is awful and the official method for levelling (bottom cover off, reset z-stepper belts) is both cumbersome and inaccurate. I swapped out the stock bolts and spacers and fitted manual adjustment wheels to allow the use of the SCREWS_TILT ADJUST macro (and others!).
I'm guessing these should work on the K1 too, so if anyone tries it on the K1 let me know and I can update the description.
IMPORTANT:
Because these wheels protrude more than the stock bolts and there are no endstop sensors you run the risk of your bed crashing into the enclosure base! To prevent this happening, edit your printer.cfg and change [stepper_z] position_max: value to 300.
Parts Required:
- 4x Bed Level Adjustment wheels (print in ABS/ASA with 70-100% infill, 3 walls)
- 4x M4 x 35mm countersunk machine screws
- 4x 20mm, 8mm o/d 4mm i/d bed springs
- 4x M4 washers
Method:
- Remove build plate
- Remove 4x original nyloc nuts, bolts and spacers
- Insert the original nyloc nuts into the adjustment wheel; they are a tight fit so tap them fully home with a spare bolt
- Fit new bolts, springs, washers and wheel in that order
- Tighten wheel so the bolt thread is flush with the wheel surface. That will give you a decent amount of initial tension, and a good start to run your first calibration
- Replace build plate and home xyz axes
- Don't forget to edit your printer.cfg as in note above!!
- Run whatever level calibration you choose. One notch on the perimeter of the wheel correspond to 1/24 turn, 2.5 mins or 0.03mm (0.7mm pitch on M4 screws) of height adjustment so it's easy to get it dialled in.
See photos for my first attempt - from >1mm to 0.17mm variance :)
Troubleshooting:
If you get an error: “AI detection prompt key:506, AI LiDAR calibration failure” when starting a new print, the reason is that the white LiDAR calibration sticker is too far below the bed level. Tighten all 4 screws down more to bring the bed lower (<3mm difference between the sticker and build plate surface seems to be OK) and recalibrate.
