yes you always get one, it is the seal that gives you the pressure that makes the plastic come out of the nozzle. What I cannot explain is the double bulb though, perhaps it was an artefact from pulling it out?Quote

Jelle - By saying "you can_not_not_get a 'bulb'" do you mean that you CAN get a bulb?

Okay, I finally removed the retraction completely and starter to use the web interface, the result was great, with no skipping! But now I have another problem! The retraction made the prints look nicer, but most importantly, I could lift Z so I wouldn't damage the print! So what retraction settings are you guys using that actually works?
I will also try the "avoid crossing parameters" function to se if that helps. Now it sometimes "scratches" off the first layer because I can't lift Z!

nah the bed isnt the problem, im talking about lift z when retraction is triggered. so when it travels, it lifts the nozzle a little bit..? or am i wrong here? just completed a print anyways, without retraction... oh my thats gonna need some serious cleaning! gotta try out some more retraction settings! i tried 1mm up to 3 mm retraction, with speed from 20 up to 40... it always made the nozzle clog and extruder started skipping. without retractioin there was barely no skipping, but i just cant get rid of it completely! i guess i just have to try more settings! =)Quote

I don't know what you mean by "can't lift Z" ?? If your scratching the first layer you probably don't have the bed levelled properly - see my previous comments. I was using 4.5mm for a retraction setting and I reduced it to to 3.8mm just in case since my recent bout with a jammed extruder. Seems to work fine either way.

Yeah, have you calibrated extruder steps/mm yet?

I removed the fan duct, and I'm now printing the first layer at 215 and the rest at 210! Haven't tried to go up even higher and put it back yet, since I'm facing some other problems right now I'm dealing with!Quote
upsch2000
try increasing print temperature i am printing 220-230 depending on the filament brand
I hope it helped
