Now that the X axis modifcation is nearly complete, I’m officially starting on the Y axis. Partwise this one will be much more simplistic than the X axis, except it is going to require 4 very precise holes in a heated bed mounting plate. I’m waiting on parts for my initial mockup Y axis (unless someone has a spare Taz y axis they want to send me? No? didn’t think so) so this one will likely be a couple weeks in progress before I have anything significant for it.
I’m going with the same Openbuilds wheels I used for the X axis, but a pair of 20mm x 40mm rails this time instead of the single 60mm unit.
Here are the initial mounting parts:
You will need 4 of the corner pieces, and 6 of the support pieces for the Y end. The support pieces are there to provide additional axial rigidity along the bed travel path.
Aside from the additional holes in the bed plate, this modification will be largely bolt on, and will require no firmware modifications.
My current thought is to make some printable drill guide templates. This is one of those projects that is going to work great if you get the holes right, and not at all if they are off. The other option would be to try and make some sort of intermediary printed part and mount the openrail hardware to that, which would probably work in the short term, but it wouldn’t be strong enough in the long run to matter. If anyone has a better idea, please let me know what you think.
