Monoprice Ultimate 2, Filament feeding gear stripped.

[Oliveros 11]

Hello everyone,

 

I was having issues feeding Ninjatek Armadillo, it kept getting wrapped up in the feeder gear despite earlier rolls not doing so, after speaking with the filament manufacturer and the printer manufacturer, they kind of pointed at eachother, so I decided to just take the head off and look at the gear.

 

It semeed like it was worn, even to the point of the gear teeth being slightly bent in, which I figured didn't help. I then spoke to Monoprice and they said they didn't have the part and probably wouldn't get it, and that I should find another one somewhere in the future when I need it. (They are sending me another replacement printer as mine is still under warranty)

 

So considering it's now a dead giveaway that eventually I'll need to replace this gear, how would I go about finding one?

 

I'm assuming the amount of teeth is extremely important as that would dictate feed rate, correct?

It's not really a gear so it's the diameter that's important.  Hard to believe that it got deformed though.  Maybe you can take a micro file to it and fix the teeth.  If you find one that fits the motor shaft but the outer diameter is a little different you can probably get it to work so long as you calibrate the steps/mm of the E motor.

Okay, well that's good to know.

 

Where would I find something like that, I have a Monoprice Ultimate 2, 

 

Is there some place that sells all kinds of 3D printing gear or whatever it's called?

 

I don't think I can calibrate steps, at least I don't know how to.

It isn't very difficult and there are a lot of youtubes on calibration.  You will want to do it anyway.  It's a basic tool for setting up the machine.

A google search should turn up the filament drivers, gears, rotary gizmos...whatever they're called.

 

(A 2 second search turned up Gulfcoast robotics.  They have my gear for $1.99)
