I changed the retract at the end of the print from 20mm to 12mm in Ultimaker2Marlin about a year ago. I've made only good experiences with that so far.

That sounds smart.. I also had a lot of issues with too long toolchange retraction on the dual head machine.
Where exactly do we find it in marlin?

Hey,
Thanx for the feedback.
I guess your problem is the teflon coupler that is deformed and needs to be inspected/replaced
@Nicolinux; Yeah mate that was my first guess as well.... sadly I ordered a complete new extruder kit and replaced the whole bunch and still the same result.

@Dimensioneer; Thanx mate I will try this one..... Seems worth the try. Can you tell me if this manual covers the knowlage www.extrudable.me needed to change the code????? I will let you know if it worked for me.
Most of all I'me troubled by the idea that more people should have this problem right? I've got the printer now for about 1 year and use it quite often.......
Cheers!
@lencon: ?
Ok, here is another idea. Check (somehow) that your temperature sensor sends proper values. I'd imagine that it would lead to the problems you describe if the printer tries to extrude filament and thinks he has the right temperature even if that is not the case.
Hi Guys,
I adjusted the retract to the 12 mm, and uploaded the firmware to the UM2. This seems to help quite a bit..... When starting a new print the material starts flowing sooner, Still It has some trouble (a helping hand/push just before the feeder motor is sometimes needed) since it starts overloading the feeder on occasion.
yours

Usually this should be no problem as this is the standard procedure for most UM2 (that is if they updated their firmware). I guess your problem is the teflon coupler that is deformed and needs to be inspected/replaced. Usually you'd have problems with under extrusion too when the coupler is deformed allowing the filament to expand creating a "plug".
