Y Plates - new version


(Neil Ferreri) #1

Does anyone have a drawing of the new Y plates? I see the new ones are flat across the top and have only one hole (5.5mm?) for the belt clips.
I’m planning on building an SO3 for my classroom with leftovers from upgrades, and I’ll have the plates made.
Anything anyone would change about the plates? I thought about opening a slot for the belt and making an external tensioner, but I don’t know it’d be worth it.

I’m afraid that the changes of summer 2016 have not been published as drawings. The original drawings are at: https://wiki.shapeoko.com/index.php/Shapeoko_3#Drawings — it may be that someone has done this at one of the links at: https://wiki.shapeoko.com/index.php/Parts#Source_Files

Thanks Will. I’ve looked through the stuff published in the wiki and the other forum. I have the original Y drawing. Any ideas what the changes were? And why? Since I’ll have to have the plates cut, if like them to be the most ideal version.
The only things I see are the straight cut across the top, the change to one hole for the new belt clips, and the missing holes that serve no function on my current build.
Anyone with both versions want to chime in?

The changes (working from memory):

  • change from slotted motor mount (which was used to tension belts) to mount using PEM nuts
  • switch from M3 to M5 belt anchors

Possible they cutout notch for wiring shifted?

The other holes (for extrusion, Delrin V wheels) should be unchanged.
