I’ve just finished building the itworks titan aero extruder and i am having stepper motor issues. I am using the motor that is supplied with the Aero kit from e3d
I am using 3mm filament ( i know its not quite 3mm but hey…)
I can feed filament in ok and but when extruding there is stuttering, it starts to extrude ok then stutters. If i pull the idler arm away from the hob gear slightly it stops stuttering and extrudes fine. At this point i haven’t even tightened the idler spring, doing so makes stuttering worse.
Is this a classic example of backlash or is something else going on?
Gears are aligned, might be a small discrepancy of .2 of a mm as it looks flush.
