How to lower Z in first layer to add squish?

[andrey]

Hi - I’m trying to make the first layer be a bit more pressed into the plate (normally would use live-adjust Z for this on a Prusa). Is there any way to do it? I’m using the Engineering Plate.

I found some other posts about it previously but there didn’t seem to be conclusive answers. The closest I found is this thread suggesting the way to do add Z-offset with code, which I am trying to do but the results seem the same - so I’m not sure it’s working:

Maybe I’m putting it in the wrong place? Or it’s not the right thing? Any help appreciated. TY!

Figured it out. For posterity, it goes into the Machine Start G-code section.

;===== for Textured PEI Plate & Engineering Plate , lower the nozzle as the nozzle was touching topmost of the texture when homing ==
;curr_bed_type={curr_bed_type}
{if curr_bed_type==“Textured PEI Plate”}
G29.1 Z{-0.04} ; for Textured PEI Plate
{endif}

{if curr_bed_type==“Engineering Plate”}
G29.1 Z{-0.02} ; for Engineering Plate
{endif}

This was super helpful and more info and instructions can be found there: Printables

I get this issue with your code. are you able to run yours with engineering plate

[andrey]

Hmm yeah it works for me. Make sure you’re including the first line, it seems like it’s not recognizing the variable?

[Nav10886]

could you try slicing a file with engineering plate selected ? Would be much appreciated

The error maybe related to the " sign. If you have copied it from the browser, it maybe replaced with a simular one. Try to replace the " signs by typing it with the keyboard.

I would be careful with this

Thank you. that fixed it. Now to see my nozzle in air issue gets fixed.

What I mean

With the redundant bed leveling I fail to see why this is even needed. Have you done a calibration recently?

We have three X1-C, never saw this problem.

I find better first layer adhesion and appearance with a bit of squish for petg on engineering plate.

hi , how can I lower z offset using Cool plate bed?

Why not increase first layer width? It would give the same effect I think.
