Semi-cross post from Jon's other X & Y thread. This is about both the Y and X Upgrade
Started installing these mods. I kind of wish I waited to use my black PLA to print the parts, but the amber/orange doesn't look that bad.
So far everything on the Y axis has fit nicely. I had to print the Y/Z block twice, since Slic3r messed up on two of the bearing slots. I'm probably going to be using Cura to slice from now on. The zipties I have are a lot softer than the one that came with the Printrbot. This results in some slight play if some force is pushed on the rod, but overall it's a lot more rigid. I guess this will help when I accidentally run the Ubis into the bed.
Still using the stock acme rod. I haven't found a good place to find a two foot long rod. I did find a 3 foot long one on mcmaster, though. Unfortunately one of my Y rods isn't made all that well, and has a lot of resistance with the bearings. It's a tad too big and uneven. Gonna try and get it replaced.
I would like to do the cable management as well, but I have a spool holder in that area. I was wondering if you could possibly put the cable management and spool holder together somehow? That would be the best of both worlds.
The X was relatively smooth so far as well. I did have some problems where I collided with the motor shaft before the bearings:
Probably varies from motor to motor. I'll probably just have at the printed parts with my dremmel again.
