Yes i did, hope i solved the problem a different way. I bought an ultimaker 2, lets hope it does not have the "retraction" problem like my ulimaker 1

Tried that this is the result. It looks a bit better, this is printed 210c with the retraction settings in the expert mode set to 0

Thanks for the detailed feedback and spotting two defects. I fixed the duct, it doesn't blow at the nozzle anymore. Also i tried fixing the springs and run the leveling wizard again. I see it retract when i look at the big wheel on the back, but i have the feeling it isn't always retracting when skipping small gaps.

I do see retraction happening during a print Slow speed and temperature are not helping at this moment. I did noticed that my "nozzle" keeps leaking filament when i set the temperature doesnt matter if its 200c or 220c it keeps leaking. I think that this might be the problem? but i have no idea what is causing this "leaking".

I am experiencing some problems while printing on my Ulitmaker 1 Printing on with PLA. I was trying different speeds 50% till 150% and played a bit with the temperature fairing between 200c and 220c but the result is not so good. Does someone know what the problem might be?
