dude.. have you been printing with steel cable instead of filament?
-
Haha 😂

Oof
Yeah that'd do it alright
Planing to upgrade or just repair?
-
Well I moved it up by around 3mm on the bar...so if the current print turns out, I'm good.
What upgrades were you thinking?
-
You should look into a dual gear extruder. They're a slight upgrade from this kind and do a lot better without wearing out. If you want a bigger upgrade though, look into a BMG clone. It's great for direct drive if you decide that you want to do that at some point. It has a 3:1 gear ratio so you'd need to adjust e-steps, but it's really efficient.

If you need an upgrade (or want, heh.)… I doubt you can go wrong with microswiss. At least, I never have. (Their nozzles are my bread and butter, too)
Micro Swiss has an amazing dual gear for Bowden tubes. They’re advertised as fitting creality machines but they basically just sit on top of the motor, so as long as your motor is the same size you can make it work.
Of course any of their direct drive extenders are definitely worth it

I personally have Titan extruders on both my FDM machines
They're great IMO
I hear that Revo hemera are pretty cool but they're kind of expensive
There's also the orbiter extruder which looks pretty cool too

Was that gear slipping and skipping?
-
I suspect so, yes...when I'd extrude 100mm in an attempt to cal the e-steps, it was wildly inconsistent...so I suspect it was slipping.

keep in mind that when you change the extruder gear you need to calibrate your E-steps.
100%
Even if you replace it with an identical gear? That seems unlikely. You should only have to recalibrate if you change the tooth count.
Well, what is the worst that could happen?
Even if it is the identical gear, you probably would get the same value but you are sure that it is correct since you calibrated it. On the other hand, not doing the calibration because you think it is the identical gear you could get over or under extrusion and are wondering why it happens because "it should be the same gear" and possibly look in the completely wrong direction trying to fix the result.
There is not really any harm in checking and being sure instead of assuming and then having to deal with the result.
