filament not feeding on print

Post by » Fri Apr 12, 2019 1:31 pm

my Up box plus has just developed a strange fault after 2 years fault, filament extrudes ok and extracts ok when loading a new roll of filament, but after doing a manual level test to make sure all is ok, once the print starts the drive gear is just clicks like there is a jam and no filament is drawn in, i stop the print immediately and extrude some filament manually it comes out fine, so no blockage. i have changed the head with a new one today ( New ABS variant ) set it up and the same thing happens, extrudes manually but not during a print! ive had no issues with this printer up to now, all i can think it is is something wrong with the latest software update?

HELP! :oops:

OK, silly question first, after the bed level did you set the nozzle height? If so how?

If that's good what happens if you stick a deliberate nozzle height that places the nozzle way above the bed and start a print? Does it feed OK then? If this is good increment down until the raft adheres nicely to the bed.

Do you level the printer while the bed and printhead is hot? Both expand and will cause less clearance when hot
