Bed Leveling

Open onkelfunny opened this issue 4 years ago • 4 comments

Hello Chris,

can you tell me which version you are testing with the SKR board? For example, I can't get the bed level to work with version 2.0.3. If the 49 points are tested, the distances are all ok. When printing, I have extreme problems with the first layer. The distances to the bed always vary on the y axis and are sometimes 5mm.

Do I have to do something to calibrate the bed? I have activated the bed leveling under "Motion -> Bed Leveling" and also rebuilt the mesh.

I am sure that I have missed something... maybe you have an idea? Does your SKR printer print in general or do you have problems with it?

Thanks onkelfunny

You need to set the Z offset. Probing gets the mesh values and you need to set how close the nozzle is to the bed. I have 6 printers running and they work pretty much spot on without issue.

the problem is that i have already set the z offset. the print usually starts very cleanly. but suddenly the nozzle moves to the wrong position.

just so i understand correctly. do you mean the function "PLA z offset" under "custom menu"?

Would be cool if we made a short video... "setup after firmware flash for dummies" :D

I have now completed:

1st Full Calibration 2nd PLA Z Calibration => The result was this:

After that I started printing. The profile is from this repo, so I assume that it works.

The result looks like this:

Now I have no idea what else it could be.

With the new Version 2.0.5.1 and UBL everything is working. over 40 prints without any issue :D Thanks for the new config.
