Hi, Great project!
I think install this solution on my U20 ;)
I've only 2 questions:

  • the support connected to X axes require another 2 ranelle 5mx8 where it's connected to the wheel's screws?
  • with the nema motor on top, can I've more the vibration on Z axes ?

Thank you :)

Hello,
1 - This part don't need ranelle M5
2 - No more vibration for this

Good project..
Can you please show more pictures?
For guide, to make one like yours..

Thanks

Intéressante cette modification, mais on ne voit pas bien comment tendre la courroie .

par le moteur, celui ci est monté par des trou oblong. Ce qui permet le réglage

Thanks, i want to make this project. One question: the stock U20 bar is lenght enough for the modify?

Yes you conserve the existant bar. Just buy one for other side

You could make it simpler by using bigger pulleys and bushings instead of bearings like here. Has been working for more than 2 years now.
