Problem feeder for my UM2 conversion filaments 1,75mm

[paul9 20]

hi guys!

Are two days that I have converted my UM2 to the filaments from 1,75mm but the prints despite the high quality setting with CARE software are not always good, indeed in some cases like this are really worse than when I printed with the same parameters the filaments from 2,85mm.

I have to improve the feeder according sentento me and the other the problem seems to be the feeder.

I mounted a IRobertl adapted to the filaments from 1,75mm but I perferzionare the part of the speed of thrust and retraction of the filament.

I don't know what settings with high quality are, but since you are using 1.75mm you should adjust many parameters to print right. Post the full settings used not just the name of the profile.

And sorry this I don't understand "but I perferzionare the part of the speed of thrust and retraction of the filament."

Retraction speed 25mm/s should be ok, the problem might be the 'Minimum distance to retract' Since you use 1.75mm you can lower that value to 0,50mm or 1,00 (if your feeder isn't perfect) to allow the Slicer to retract before moving from one point to another. Also increase the TRAVEL speed (not printing) to 150-180-200mm/s.

I don't use much cura at all, so other settings maybe someone else can jump in and help you.

perfezionare = perfect!

my reference values of retraction are set manually on the machine via the display.
