[Rertraction on S3 does not work]

Quote

Change "combing mode" to "not in skin".

 

Yes, that works, it retracts now. Most is gone. Only left is a string after the "Prime blob", and sometimes a tiny bit of stringing after retraction.

 

Thanks.

Whoops, indeed it's an Ultimaker 3 not S3.

 

Explanation of gr5 is clear, makes sense, fits what i'm seeing and is an setting i didn't touch until now. Thanks, i will try it later today.

Hello, I'm working with a UM3 and trying to print with two colors of PLA. This works, but I keep getting strings. I watched the video to solve this, experimented with the retraction settings, z-hop, print speed, temperatures etc. I looked in this forum. But it simply doesn't get better.

 

One thing I notice is that it seems head 1 doesn't retract at all. I don't hear it pulling back the filament. When it switches to the second head, it always retracts correctly, doesn't have any strings. But to be fair, the first 95% is done by head 1, so it continually moves over already printed material.

 

Load/unload works fine on head 1. So my guess is it's not broken, but not sure.

 

Anybody an idea what else I can try or check? Any help is appreciated
