U1 improvement: Manual Leveling Wizard

U1 Toolchanger

Improvements from beta testing: For people who are picky like me, the U1 now has a very nice on-screen wizard to assist in manual bed leveling by beta tester request.

Now having a wizard, I’ve been using it more when switching between extreme operating temps (like after heat soaking the printer with my very “fancy” homemade cover for ASA printing).

Note the scale for the mesh shown:

(For the curious, I might see an additional ~0.2 mm change in the bed tilt after the first heat soaking of the chamber to 50 C for ASA printing. And ASA is evil, so I prefer leaving nothing to chance.)

You likely don’t really need to do this. @nweolu showed the bed mesh compensation can compensate for a lot! :rofl: If you like clean living though, I think this is really nice.

Thank you, Snapmaker! Not every printer lets you see the bed mesh, let alone help you address any observed bed tilt.

This is really cool. :orange_heart:

Wow i am impressed, after manual leveling i went from 0.94 to 0.54 variance which is, horrible ! Even the cheapest china bed for a voron reaches better variance …
I am disappointed

If the bed is clean (it will absolutely detect small particles under the bed), it can help to double check the overall height of the 4 screws.

This is simply using the klipper screw adjust macro, which gets the 4 corners level. If they are out of plane with the center it may still have bowing.

I’ve learned elsewhere you can raise or lower all the screws then skip along in the procedure to the probing step. If the center is above or below the center.

Maybe the routine could be improved to measure the center point as well. :thinking: I find it a little tricky to judge the step where the nuts are flush with the screw caps.

But mine has always been <0.2mm out of the box.
Your mileage may vary.

:thinking: What was everything tried?

The S shape is very strange. The sheet was laid down flat with nothing under it?

I know, simple stuff. That’s just a very unusual mesh.

Cleaning the Bed, changeing the sheet, manual bed leveling, leveling by mesh (tried to adjust without the wizard)

I also noticed that the plastic cover is not well alligned and the bed sticks out.
But this seems to be an optical issue nothing related

I spent hours, manual leveling, running mesh again and again. I tried loosening the screws in hopes to get rid of middle bump, did not work:
Best I could do was :

Very similar result after running manual level and mesh bed multiple times. I also verified there’s nothing on the bed under the plate.

I’m wondering if this is why i’m having models not stick. And prime towers falling over?

Most likely not. If your first layer is looking wonky, run initial calibration first, make sure the build plate is removed when asked.

I ran the manual leveling process. This has made a huge difference. Plate was horrible. Also added elephant foot. Changed retraction settings for prime tower. Also stopped using snapmaker orca. Vanilla orca is working flawlessly in lan mode.
Thank you for all your help. Have a great weekend.

Doesn’t sound like you run the initial calibration again…

No after manual calibration I also ran the heated bed calibration. I also did it on vanilla orca. And set the tune there. Using flat plane and wire matrix. With massive difference from factory.

Thank you for the help. I’m having much better luck. Also changed build plate glue.
