Problem after updating firmware

Recommended Posts

Hello, I have noticed that my ultimaker dont retract filament after aborting a print. I had a issue and stopped the print. When i started the print again i noticed that the feeder skipped because (if you remember) the printer is on the first second speeding up the feeder and then when the filament comes to nozzle it reduces the speed on the normal value. Other thing from same problem, the nozzle is always oozing because the filament is in the nozzle and not retracted (i mean alot of oozing).

Sorry for my english, if you dont understand i can record a video. Can i downgrade or something? Thanks in advance

Yes, and after several restarts its the same. I figured out that when i use new function "pause" and then abort then its everything like before update. And this is because the printer retracts of the pause function. And even after finishing a print it doesn't retract back, the head goes to its 0 position and oozing. sux :(

sorry cuz i call it retraction, i mean just the "pull back" of the filament, not the retraction like in the printing process.

I have this exact same problem,

I re-installed the last versio but still the same problem. Please help i was creating beautiful printd and now everything i make is shit. I also notice that the material is not sticking it just folows the nozzle.

I tried increasing the temp. This helped a little but i don't want to do this everytime i print . It was working great before so this is a retraction problem?
