3rd screw for bed leveling?

Recommended Posts

hello,

I noticed there is a 3rd screw on the buildplate for bed leveling.

What's the use of that 3rd screw, do we need to adjust this screw from time to time?

The bed uses 3 screws to level. It's a 3 axis level system. For calibration you just turn them. You mean the ones down the plate two in front and one on the bad of the lower plate on the center right?

You can use the 3rd screw if you find that the adjustment made with the control knob on the front during bed levelling is too coarse.

Yeah, that's for leveling. As @IRobertI says, you can use it for that. On um2 it's faster to level, on my umo+ I use it always for leveling or when changing nozzles, etc. When you calibrate it, readjust the ones in the front.

On umo+, since the endstop it's on the upper side and can be moved, it's part of the leveling assistant on cura

Check minute 3,20-3,30

 

Um2 endstop it's on the bottom and the firmware assistant it's more advance (someday Ultimaker could improve it since its the same bed hardware).
