I have recently bought an Ender 3 S1 Pro and it has been a bit of a hit and miss so far. My main problem has been the Z offset. It keeps changing between prints. The first print turns out okay and then when I print the same thing again it just breaks.
I followed the steps for method one from
to level the X axis gantry which made things much better. For a while. But just recently a print failed after about half an hour. It seemed like the printer got the Z-offset wrong because the layers just wouldn't stick any more. I aborted the print and did a height map calibration:
And this how it went. The printer also made some stuttering sounds when probing the plate at the far right.
I'm using Klipper with MainsailOS instead of the stock firmware. I have updated everything to the latest available version.
It seems like I need to make some adjustments, but I'm not sure what to do. Should I try to adjust the X-gantry again? I have levelled the bed and the four corners are pretty much level. I'm also using this model to get a good enough first layer. And that works, but only for one print. Then I have to redo the Z-offset calibration as well as perform the height map calibration. I don't think I should have to do that every time? The printer is placed in a stable location and I'm not moving it between prints. I also clean the bed with IPA before each print. And I have a PEI plate.
So I'm wondering what I should try to to adjust/tweak/calibrate to get the printer to work reliably?
