Cura 3.0.3 retraction problem.

Recommended Posts

Posted (edited) · Cura 3.0.3 retraction problem.

While trouble shooting my ongoing retraction problem in Cura 3.0.3 I noticed all of the G1 lines, shown below that do not contain an E value. I also noted all of the G0 lines generated to traverse to the next location where extrusion is needed. What is the reason these lines are generated? All of the G10 & G11 lines are present in the program but the extruder does not retract the filament. I have tried .5 to 5.5 mm retract distance and 25 to 55 mm/s speed.

I am also facing a major issue using my UM2 and Cura 3.0.4.

I spent the day trying to deal with oozing/stringing without success :(

I will try installing a previous version of Cura...

I am also having a large amount of stringing problems on my Ultimaker 3 using Cura 3.03 and Cura 3.04 that was not occurring with the last version of 2.x. I think that this may be a retraction issue. I am going back to 2.x until the dust settles.
