I got a CR10 V3 two weeks ago and printed 3 small items successfully - XYZ Cube, Benchy boat, Calibration cat - all came out looking great. Since then I cannot get the titan extruder to extrude filament. I replaced the nozzle, cleaned out the throat, and I still cannot get it to work. If I remove the cover and clean the throat then put it back together I can extrude filament using the menu option to extrude. I can also manually feed the filament though and it works but as soon as I attempt a print nothing comes out of the nozzle. I have to open it up, clean it out, replace the nozzle and then retry it again. Any suggestions on what I need to do to get this thing to work would be appreciated.
