works with mk7 drive-gear ?

I don't think so. If I remember correctly the MK7 drive gear has a much larger diameter than the MK8

Hi, is it ready for use with 1.75mm filament? I can imagine the hole being a bit too big for it to fit nicely?
Also, is there the possibility to move the idler bearing a bit more away from the stepper motor? My current direct drive extruder has an MK8 gear on it, but the set screw is sticking out slightly of the gear and it hits my idler bearing, causing it to move away from the gear and slipping. I tried grinding down my set screw, but I destroyed it so now I have 2 options. Either using your extruder with a slightly better positioned idler bearing, (if it works), or glueing the drive gear onto the stepper motor.
I prefer option #1 ;)
Did you ever had trouble with it slipping because of this?
