First layer is too low MK4S

Im having an issue where every prints first layer is very low, I've calibrated x, y and z axis's many times and same results, does anyone know what could fix this?

Best Answer by Brian:

Yes that's way to low.  I guess if check to make sure your nozzle is seated properly.  Loosen the thumb screws on the side and then push up on the nozzle and tighten the thumb screws. 

You also might make sure that your print profile doesn't have an offset in it.  I assume your using the new printer and filament profiles, and not an old profile.

RE: First layer is too low MK4S

You can hold the control knob during the 1st layer and adjust the live Z.  Keep in mind that it won't remember the value as it reprobes the sheet every print. 

If you have a constant value that you want it raised by them I think you can set a z offset in the slicer, but I've never personally messed with it as I don't think it's intention is to offset your live Z, but I believe it can be used in that manor.

What material are you printing?  I've only found the nozzle too close when printing high temp materials, say above 260.

Another thing you can do is raise the nozzle temp during probing, but this requires that you didn't have any oozing as that will mess up the bed mesh.

I would first go thru the first layer issue help page: https://help.prusa3d.com/article/first-layer-issues_1804

If that doesn't help, then do a chat session with support. 

Please keep us updated as to your progress in resolving this.  There are others that have the same problem.

Loosening the thumb screws on the side of the extruder and pushing up on the nozzle and tightening the thumb screws.
