E3D titan user, when fully assembled manually moving the black wheel seems like a lot of binding. Is this normal? It doesn’t feel right…

Yes I think so, it’s using gears to have a really good grip on the filament, but the motor is doesn’t actually force as it turns fast.
You can adjust the tension with a screw, but I never had the motor skipping. I love it!

Ok thx Will find out when it’s running then

is this with the filament in there?
if not - then my experience is this should not be the case - and it means that either the smaller/driver gear is not at the right height (causing pressure in one of a few different places which results in the black gear binding) or that the whole extruder is at a slightly misaligned angle (kinda hard to explain) and so causing the black wheel to bind at specific parts of the turn (have had this happen twice when i replaced my motor to a pancake style one and needed a “beefier” spacer between the motor and the extruder).

if you want i can take a video (if that would help), but the i can turn the black wheen smoothly and easily with my finger.

no filament in. I checked my printed spacer thickness and it is 1.77mm… I can move it with my thumb but definetely with a lot of force…

Lo

I’m pretty sure it is supposed to move freely when no material is present.

Hmm changed to 2.05mm spacer still require quite a lot of resistance toturn the black wheel with thumb. Can’t even turn the wheel with index finger.

I think the issue is with the idler, once i put the idler in the motor shaft that’s where the binding feeling start. Might need to sand the shaft a bit
