Have upgraded K1 MaX and to be honest its been an unsettling journey , managed to get one multicolour benchy and ran a few longer single colour prints but then started to get various feed errors and latest situation is that the extruder isnt feeding as per video , extruder is clean and no blockages but just cnat seem to get it take the filament - have removed CFS from scenario as I believe thats ok but the errors are falsley stating its CFS but more likley an extruder or motor issue - video above is filament straight from spool and i can feel the extruder trying to grip but fails - or thats my assumption
I had a similar experience. But it turned out to be a broken wire, in my case the orange one, that allowed the motor to still vibrate like it was trying to grip the wire. Took ages to diagnose. A replacement Moons Motor and priblem resolved.
This orange wire what was it part of was it the upgrade for the extruder assembly? I am having similar issues. All these errors yet the cfs is feeding but seems for some reason the pla wont go through the extruder then gives feeding issues. What’s this moon thing you upgraded to ?
