Sovol 07+ prints suddenly won't stick

I have a Sovol 07+ that has been going great after I discovered glue sticks, but suddenly nothing sticks. I’m planning to try a G10 plate.
The PEI plate is needed to stop the Z down before crashing into the the plate. If I add the G10 1.5 mm how can I prevent the head crashing into the G10? Thanks.
I’ve been levelling before every attempt.
Next day - I see that using a G10 will not work.
I’ve levelled the bed with a spirit level.
Did the corner levelling which put the bed way out of whack.
What hell is going on here?

Update
Restored factory settings
Manually levelled bed with spirit level.
Z tilt
Z calibrate
Bed level using screws adjust only
Bed Mesh

Is now printing good again.

Spoke too soon.
First item (small) printed good.
2nd, 3rd and 4th items (large) started ok but after 10 minutes or so were wiped off the plate.
Very frustrating.

If you are using PLA, try bumping up the temperature 5c, So like 60c to 65c. The thermister can easily be off by 5 or 10c. Another thing to try, is to adjust the z-offset while it is printing the first layer. Maybe try doing some first layer test prints to get it dialed in.

I am using and SV06, and I need glue sticks for large PLA prints. I put the gcode, in the slicer start settings, so it does a 25 point auto bed level before every print. When the z-axis is out of alignment use the soup can method to reset it. When the z-offset is off, I adjust it the way I described using first layer test prints. And when the build plate is dirty, I clean it with dish soap and water. I try to never touch the build plate with my fingers, as that puts oils on the build plate and prevents any material from sticking. I print PLA with temps set to 200c nozzel and 65c bed.

Thanks ajwsurfer. “Soup can” method?
" I put the gcode, in the slicer start settings, so it does a 25 point auto bed level before every print"
That’s a great idea. Can you tell me the gcode for that please?

Here is the gcode in my Cura Slicer: under “Settings | Printer | Manage Printers | Sovo SV06 | Machine Settings | Printer | Start G-code”.

The line “G29 ; Auto bed leveling” does the bed level.

The “;” character comments out any thing on the line after it, so you can add notes.

WOW - thanks so much for this :slight_smile:

The “soup can” method is described here starting at 8.00 https://www.youtube.com/watch?v=BH7nQ1z6Y1M&t=1s

Ahh - thanks for that :slight_smile:
