got my X1C yesterday and tried to print the banshee. Got 2 problems:
As you can see in the attached video the AMS is feeding till the tool head. Then the AMS tries to push the filament into the tool head but the tool head doesn’t catch the filament. This procedure repeats 3-4 times ending in an error message, that the filament cannot be extruded.
Without the AMS everything is fine and I can print models.
When the AMS retractes the filament it does not roll up properly. When it tries to push the filament through the tubes it stretches the filament too much on the spool and the spool jams.
Tried 3 differenz PLAs (bambulab, geeetech and sunlu) on 3 differenz chambers.
Problem number 2 is normal so far, I have it all the time too.
The fact that the filament is pushed into the AMS faster than it is rolled up is a peculiarity. This mainly occurs with full spools with a lot of weight. As there is no lateral limit when the spool is too full, the filament is pushed to one side over the adjacent spool and then gets caught when the spool has finished winding. The problem is that if you have to pull the filament out completely because of this, the K value for the filament is lost in the middle of printing.
