Autohoming / Bedleveling not working

Sovol SV06 Fully Open Source 3D Printer

Hello everyone,

I have some trouble regarding the Autohoming and leveling function. After a power fail the printer forgot the correct height of the Z Axis Nozzle. Everytime my printer will try to home / level the plate it will stick the nozzle into the printer bed. I tried a factory default reset, but had no luck. I am pretty new to the topic here so I would like to get some advice from you how to troubleshoot and solve the issue.

What I did so far:

  • performed a manual set of Z Axis params via G Code Commands
  • checked Z offset / tried to set values manually
  • tried “the paper test” > fails with the stucked nozzle
  • tried autohome

environment:

  • Octoprint
  • Sovol SV06 Plus
  • Printer Firmware V1.1.5 (Marlin Version 2.0.9.2)

(edited due to non exact environment definition)

I had this also a time ago. The vertical detector on the printhead was moved a little bit.

Found some topic of re-adjusting/resetting on this forum; forgot where exactly, hope you can find it :slight_smile:

Edit : found Autohoming / Bedleveling not working - Sovol SV06 Fully Open Source 3D Printer - Sovol3d forum and Auto Home crashes into bed - Sovol SV06 Plus - Sovol3d forum

Hello,
Did you remember to save the settings after performing the automatic leveling?

Hi and thanks for the quick reply. I had no “save” button or similar. I tried to do it via G-Code Command, but had no luck. Therefore I consider either I missed a peace according to the leveling guide here, but I do not see my mistake.

thanks for any advice

regards

Carsten

I don’t own the SV06, but I do have the SV06+, and I haven’t used it in a long time.
But, if I remember correctly, when I was performing an automatic leveling, I think there was a “Save” button at the end that you could easily forget to click.
Unfortunately, I’m on vacation right now, so I can’t give you the exact steps.

One more thing, have you taken a look here:

Thx @Lion , on my smartphone it’s not so easy to find something

Also pay attention to the LED on the proximity switch. If the light doesn’t come on before the nozzle touches the bed then it is defective.

Hi there,

I have tested along with the manual again and was able to figure out, that the sensor for z Axis has been to high. So right now levelling will work fine and I can save the config. While I am using octoprint after slicing from Orca I run into same issue. After a print the sensor will not measure the endpoint correctly. So if I will print and want to home the head again it will immediately fail. So after a reboot everythings fine again.

Is it correct, that this will happen?
