Hi - This is my fourth print following a clicking filament drive problem? I cleared the nozzle, made sure the feed tube was correctly inserted into the hot end. It printed the raft good, I think?, then the deformation started to happen? the nozzle even scrapped across the filament ? Any thoughts as to what is going on? Please see pic attached.
Post the filament are you using and at what temperature are you trying to 3D Print.
Makerbot PLA 200 degrees
I am noticing that raft or not the first layer is patchy, not joined in the direction of print.
This could note under extrusion, though your raft is looking good.
Is the print speed or temperature changing during print.
I started with PLA printing a 192C now printing PLA at 208C
