I finished adding the X-Y openbuilds mod by piercet. I modified the cable chain mod for the X-Y-Z and wanted to share in case someone wanted to do the same. I did the X-Z chain this way because my enclosure limited the vertical space for the x-axis chain when at max Z.
X-Z Cable Chain
The X-Z cable chain bolts into the frame, x motor mount and x backplate. You’ll need 6x M3 heat sets to screw the cable chain ends on the x-axis. For the Z axis, the chain snaps into both ends. The cable chain holder screws into the belt screws from the x backplate of the openbuilds mod.
I used this cable: http://www.amazon.com/dp/B00PZMDJHE which is nice since it’s open lay, in case you want to add/remove links without unscrewing or re-feeding the cable.
