Flashforge Creator Dual / Pro How to fix Dual Extruders dragging across prints.

[Geoff]

And clogged nozzle fixed - tried 250c preheat and pushing it through, no dice, so i disassembled and found this:



so i pre-heat to 250 again let it cook for a minute, and grabbed it with a pair of pliers and it came straight out.. no force at all.

I'm getting reasonably proficient at removing the extruders.

Ahh I see what you mean about the offset, ah well , it's not like you need to adjust it often and as you said, you are getting handy taking them off. It's only a couple of screws really isnt it for an extruder, im glad they made it as basically constructed as they did, makes my simple brain work much less harder.

I appreciate the great pictures. However, when I tried to remove the screw I found that my hot ends (and the whole square heating element) screw in instead of slide up. My right side is about 1mm higher than my left side. I tried loosening the hot tip on the right side to make them even, wasnt a good solution.

Is your hot end assembly threaded also? One other tidbit, I thrashed the teflon tape wrapped around my heating element. Is it horrible to operate the machine without that orangish brown tape?

Just for interest, this is the procedure I used to align the extruders.
First - align the bed CAREFULLY with the one extruder this is an extreemly important step and must produce a good result.
Second - using the information on previous posts release the higher of the two extruder tubes.
Third - use the baseplate to level between the extruder tips (I used a thin metal foil on the base to act as a reflector to help to see when the hights were the same).
Forth - with the base still in place screw the nozzle in place.
Fifth - screwing the nozzle up (tightening) can cause the nozzle to change hight so check again for both nozzles in contact with the base.
Sixth - reassemble the extruder and re-check.

now when you level the base next time be sure to check the hight on both extruders at each step. There is an advantage with dual extruders, it is easier to set the bed level as both extruders have to just clear your paper at each step; any tilt will jam one extruder or the other causing the paper to pivot round that nozzle.
Hope this helps others. Regards, Paul.

Hi, I am new here and I literally just got my printer yesterday, and I have a problem. When I use FlashPrint, I set my preferences to "Left Exturder". But it starts printing (Or trying to print) with the RIGHT exturder and vice versa. I spent like an hour trying to figure it out. I am not sure if it falls into this forum, but why not.

Select the displayed object, right mouse-click, and select 'Choose Left Extruder to Print'. If printing with the left extruder, the image will probably be displayed in green. If with the right extruder, the image will probably be displayed in yellow.
