Put the Bowden box back together but still same issue, leading me to think I need more power to the stepper motor, how can we do that !?
Another option very much needed in Cura not on the Ultimaker is to extrude fast & like 20cm or so, that's handy when you replace the filament or do maintenance, the older version Ultimaker didn't require that since at the Bowden tube you could release the lever & push the tube, until it reaches the extruder. with this one you cant & have to painfully click extrude button like a 100 times in Cura.
Sander: I am not sure what parts are required to fix this problem with slipping, but I assume you know, so please provide these too unless its something I can do in the software/hardware.

Retraction issue:
Okay so its not the retraction but rather extrusion, so if for example I click the extrude bottom in Cura 3 or 4 times quickly to extrude say 30-40mm material than I keep hearing that sound & I can see that it somehow might have an issue extracting that much material or something, not sure how to fix that yet, but its defiantly extrusion problem.
EDIT: Seems that its slipping, there is a set screw at the back for tension & if I set it to loose it slips all the time & if I set it to highest tension is better but still slips if I extrude quickly.
seems like two things to me, either stepper motor needs more current or I need to set temps to 220c as now I'm extruding @ 210c.
EDIT-2: not even 225c works, defiantly stepper motor slipping (skipping) set screw help a little when set to more tension (White mark at top indicator) but doesn't fix the problem.
might need to open that Bowden box at the back :mad:
EDIT-3: After opening the Bowden gear it seems that it actually works better with "LESS" tension as in the white indicator on top & not screwed all the way in, here is a picture of it when at least tension, but I am still getting lipping even though its set at lowest tension, so not sure what to do.
Here is the set screw usually at the top to increase tension.
