3.3.3 Leveling the print platform
After you have correctly calibrated your nozzle height, check that the nozzle is
at the same distance at all four corners of the print platform. If it is not, you may
need to adjust the platform until it is level with the nozzle at all 4 corners. There
are 3 screw and 3 spring washers under the platform heater.
Loosen a screw and the related corner of platform will rise. Tighten, or loosen,
the screws until you have the same gap between the nozzle and the platform
at all four corners of platform.
Modification: One of the Up forum users, Drew Petitclerc, reports an improved
level adjustment system, in which he has replaced the spring washers with a
small stack of rubber disks which allows much more freedom and precision in
leveling the platform. He removed the three shorter M3 screws and spring
washers and replaced them with a stack of high temp stiff rubber disks
centered between the three longer M3 screws. You adjust the level by
tightening the appropriate screws and compressing the disks. Always adjust by
tightening the screws, never by loosening them. The stack gives you a central,
compressible, pivot point and three screws are optimal for balance. Add or
remove disks to set overall Z spacing of plate to support arm.
