I recently made the switch from the marlin-based stock firmware on my anycubic kobra 2, to klipper. I didn’t have issues with bed levelling or first layer on the stock firmware, but I’m having significant issues running klipper. The bed is uneven, the probed mesh shows a deviation of 0.197mm, it was the same when running stock FW+octoprint.
But it seemed to be correcting just fine for this on the stock FW. I got a consistent decent first layer across the entire bed.
With klipper, it’s absolutely impossible to get it to correct for this unevenness. Half the bed will get perfect first layer, but then the second half is either way too squished or hardly connecting to the bed. And it’s causing further issues as it’s also hitting the print when moving, despite having Z-hop of 0.3mm for travel moves.
What the hell is going on? How do I fix this?
Yeah i actually ended upndoing something similar. Took the hotend and entire bed assembly apart, cleaned and lubed the rails and reassembled. It’s been working fine since.
