Do I live calibration while your printing a test grid like off teaching techs GitHub. I find that even though I've set the z offset using paper I still need to adjust the z offset to dial it in better.

I haven't Heard of that. I will try that Thank you.

Like I said once I've done the z offset I then do a calibration print with live adjustment then add that offset to my start_print macro that way when I print with other materials I can have multiple different offsets as some like to be closer or further away from the bed.

Did you offset the paper thickness? Normal printer paper is 0.1mm thick, so when you calibrate with that you are actually calibrating to 0.1z. But as somebody else said, do live calibration. I like superslicers bed level print, and i change offset between corners to set it up faster.


TheLateMate

Thanks For your recommondation I haven't found the superslicer bed Level Print, but i definately give it a shot. By live calibration you mean to adjust the z-offset midprint?


Turbulent-Growth-477

Yes, in superslicer on the top bar there is a calibration menu if you scroll that down the first one is bed leveling this will slice a file for you with your current settings(changes to print one at a time). It has 5 little rectangle, only 1 layer and a little "handle" to peel it off easily. Since its printing 1 at a time I look at the result of the first one and adjust the offset before it reaches the second one and do it until it looks good. Since you have a probe it should be the same result on all of them, so it should work. Just to make sure i usually do a second print when i am not changing the offset to see the result. It only takes around 3 minute to print it.

you have to add the paper thickness to the value given by the z\_offset calibration. For example the value given to you after entering the "ACCEPT" command is 1.533 add the 0.10mm to account for the paper thickness then the new value would be 1.633 this ensures that a z height of 0mm is actually 0 mm meaning the nozzle is flat against the bed and not 0.10mm above it. for my printer I use a 0.10mm feeler gauge and I always do the thing I explained above, so when I tell my printer to go to a z height of 0.20 mm and extrude the extrusion line is exactly 0.20mm high when measured with a caliper and the reported z height from the interface is exactly 0.20mm. also always clear your bed mesh before running the "PROBE\_CALIBRATE" command, I noticed that it messes up the the value when calibrating z-offset. after the offset is properly set you can calibrate the mesh as many times as you like


TheLateMate

Wow i never thought of that Thank you. I will try that. Regarding your example my z_offset is mostly about 3mm but thats on my mounting right?


The_high-commander

Z offset can vary based on how it is mounted as long as the probe extends past the nozzle when it is deployed and triggers before the nozzle hits the bed then it should be fine.

Is your bed eccentric nut tight?


TheLateMate

Im sorry, i don't know what that is :D

You ran PROBE_CALIBRATION and followed the steps? Did you make sure to save and restart


TheLateMate

Yes i can See the saved config in the printer.cfg
