Manual levelling Ultimaker 3 Issue

[essjaykay24 0]

Hi

 

I'm trying to manually level Ultimaker 3 after some print issues (not getting good first layer in one corner)

However I cannot get the bed 1mm away from the printhead/nozzle.  The closest I can get it is about 5mm with screws backed all the way off (until they actually come out!)

 

When Active levelling you can see the bed pushing against the printhead /nozzle. if i leave it like this

 

Can anyone help

During the first pass of manual leveling the encoder wheel (besides the display) is used to move the buildplate up. The screws are only touched for the later fine tuning.  So - carefully follow the instruction on the little screen and note the wording difference (wheel vs. screw - if i remember right).

I think it's a good practice to fully tighten all three leveling screws, than loosen them one or two revolutions (all screws approx. for the same amount), than start manual leveling.
