Hi, I’ve not been able to solve the problem so far. Actually I’ve been so frustrated with it that I left the X1C for months without using now. I hope you solved the problem and help me?
I suggest you to change all the PTFE tubes if you have not already and do a factory reset. Also in the slicer select the material as generic PLA instead of Bambu PLA and give it a try.
I had a very annoying problem when printing, underneath it all extruded, calibrations and stuff were useless, then I saw this post and in 10 min I solved everything. Restored to factory settings and solved it!
Really thanks for sharing!
