UMO+ Changing the feeder motor for the um2 motor?

Recommended Posts

Hi,

I want to change the feeder motor for the UM2 motor + using IRobertI feeder. Specially to lower the noisy retracts overnight.

I only found this

http://www.exp-tech.de/stepper-motor-68-oz-in-400-steps-rev

But the inner axis does not have the small 'flat' area to place the filament grip 'thingy'. Anyone knows if the motors can be unassembled to change the axis or shouldI find other motor with the axis preassembled (but I didn't find any except on china).

Thanks!

The real noise killer is to decouple the feeder from the rest of the printer. There are designs on Thingiverse (sorry, no links handy) that basically puts the whole extruder on a big springy... thing. This greatly reduces the noise. You can try it yourself by simply unhooking the feeder and holding it in your hand while you're printing, you'll notice a massive drop in noise instantly.

I don't know if it is true or not, nor on which technical basis, but I have seen in the past on several websites that they are strongly recommending not to disassemble a stepper...

But you can easily make a flat on the axis with a Dremel tool and a file.

Afger holding yhe extruder in my hand I see what you mean 100%. It reverbs like a resonance box.

I was using your feeder with an mk7 (because I use 1.75) and the retracts where almost nothing but yesterday did some mod on the original feeder and it's working superb. I first thought was that because the extruder with direct and 100 esteps didn't make noise I though that was because the amount of steps it uses to have the great torque needed. (With direct the extruder failed a lot with more than 3mm2 speed. But your are 100% right. The box amplifies the sound. I'll get my semiflex and print a barrier. Thank you very very much.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
