NEMA 17 Support for Ultimaker by fernandoafonso Dec 10, 2012

Description

X and Y axes NEMA 17 stepper motor support for Ultimaker.

This support is to be used instead the wood or plastic support included in the standard kit. This support give more grip for tensioning the belt and more space to play between the timing pulley and the wood and the same with the motor.

Yes, the screws are getting loose. So I solved it with some Loctite :)

Hi Pablo,

I'm printing at 200mm/s and the belts don't loose tension, maybe you're giving too much tension at the first time? Draw a little mark between the screw and the plastic support to see if the screw is turning with the printer vibration.

I printed it in Black PLA and resists the hot motors nicely. The only problem is that even though I tighten the screws like hell, the belts loose tension with time. I haven't tried it for too long, so I don't know if it is the support not working or the belts getting longer with use.

Could this be printed in PLA? I'd think the motors get too hot for the PLA so it would get soft.

Hi Jan,

Yes, it was printed in PLA.

"(...) maximum motor external body temperature of 125°C (...)"

"(...) glass transition temperature between 60-65 °C (...)"

Actually, PLA can reach the glass transition, but it won't melt. Too much heat is a signal that something is wrong with belt tension.

I do have to print it in ABS...

So far no problem at all, but I need to print something bigger to actually confirm your concern. :)

Thank you.

Very nice sir

Can you post a photo of it installed on your machine?   And, specifically, how it addresses the tensioning issue?

I'm about to replace all the motor bolts as mine are stripped from re-tensioning the belts so often.   I'll print a couple of sets of these before the next time I have to re-tension.

I had just upload two pictures for you. I doubt the motor move from it place with this design. :) Your printer must be properly calibrated to be able to fasten the bolts. Please feel free to tell me how to improve my desing.
