Bamboo Lab X1C with PETG-HF with all updates.
Observation 1: After the bed leveling is complete, the head moves to the front left and increases the temperature to 230 degrees Celsius, and then back to 140 degrees Celsius without moving. This results in a blob on the nozzle that isn’t wiped off, but the head starts dirty during the lidar scan, which checks the print plate before the first layer is printed.
Observation 2: After the first layer is complete, the layer is scanned with the lidar, and then the head moves to the poop bucket. However, this doesn’t seem to be happening entirely correctly, because cleaning the nozzle after the temperature reaches 230 degrees Celsius seems to miss the wiper, resulting in a dirty nozzle that loses its PETG blob somewhere along the way during printing.
I’ll be following this , as my X1c has similar blobs dropping in the print during fist layer check
I’ll try and check if the behaviour of the head and temps are the same
which firmware is running on your X1C ?
as the problem is still there even with the latest firmware, I ‘ll wait to update my printer and AMS : there should be a firmare allowing the AMS update from the SDcard of the X1C (my machine is in LAN mode, so no Bambu Handy)
