First, let me be clear I am a total printing rookie…
History…
I was having some issues with prints randomly moving off the print and printing in space. Reading suggested that an upgrade to the firmware may resolve the issue so I proceed to apply Snapmaker-GD32Base-2.11
Current Issue…
None of my prints seem to be willing to adhere to the bed. I have tried several files. Cleaning the bed each time. I have also tried leveling the bed several times, all with no luck. The video shows my current results.
Per the documentation I am using a sheet of printer paper to gauge height and then nudging down until the paper has some resistance. Do you have a better recommendation for adjusting the Z axis?
The gap here is clearly larger than 1 piece of paper
Something has gone awry between you setting it to a sheet of paper and this print starting, and you need to resolve that discrepancy.
It’s not obvious to me what the cause of that discrepancy is, so I cannot offer any specific guidance on that at this time.
You should be able to manually command the movement in Luban, try nudging the nozzle towards Z=0. Once the machine is reporting a height of 0 then it should be a sheet of paper away from touching the nozzle. Based on the above screenshot it appears to be at least a full mm away from the bed.
At a height of Z=.2mm or something you should be able to move the nozzle all around the bed and the height should be constant. If that’s not the case then bed levelling is not working correctly.
Did you recalibrate after the firmware update? The v1 loses its calibration when updated.
After the paper calibration, I like to print a 0.05mm thick sheet that’s 100mm square, pretty much like brent113’s 2nd picture. Then I’ll manually adjust the 4 corners based on these results. I can dial it in just using the 2 outer walls pretty quickly, then print the whole square just to verify that I’m over extruding the first layer.
Post recalibration and applying the slower first layer tip in the video I got a pretty good coverage other than the 3 corner. I used the object found HERE to run my test.
