I'm in the process of building Richraps' awesome little Delta printer. I wanted to get away from using the linear rail and instead utilize the V-slot channel from openbuilds for travel along with using GT2 belts.
The idea was to design an all-in-one carriage that takes the mounting of the arms and hall effect sensor mount and integrate them to the mini v wheel plate and also add a belt tension mechanism.
Thanks to all that posted the following sources:
after some Tinkercading, here is the new system! Enjoy :)
EDIT: i've updated the hall effect sensor post to have it as far up as possible and added some more clearance to the belt groove.
feel free to post any comments or let me know how this worked for you.
I made some bridges in the line tension gizmo for easier printing. cut them off with a knife and to fit a longer screw for belt tension,drill the small hole all the way through.
