New project! This time I want to see if I can’t eliminate the X axis deflection from the unsupported rails of the TAZ. The project should be 100% bolt on, no firmware upgrades required, using existing hardware as much as possible. You will need some heat set inserts and some bolts, along with the following Openbuilds Openrail components:
1 60mm x 20mm Openbuilds linear extrusion, final length to be determined. http://openbuildspartstore.com/black-v-slot-linear-rail/
4 sets of bearing wheels (http://openbuildspartstore.com/xtreme-solid-v-wheel-kit/ or other sets) ,
2 spacers (6mm probably) http://openbuildspartstore.com/aluminum-spacers/
2 eccentric spacers http://openbuildspartstore.com/eccentric-spacer/
one of their Gantry mounting plates. http://openbuildspartstore.com/v-slot-gantry-plates/
Bolts and nuts (M5, Lengths to be determined.)
I’ll get more specific on that when i get closer to having this operational, but I am still tuning some of this so part list may change
This bolts in place of the existing X axis printed pieces. I wanted to include a Y belt tensioner, so the idler pully can be adjusted inwards. I’m not 100% happy with what I came up with for the motor mount, but its about the only way it fits in there without drilling holes in the openrail so you can screw the motor in place or offsetting the mounting points a rediculous amount. There will be a Taz style plate overlay for the gantry plate for now, I may work up something different further into this one. Right now the X carriage will have about twice the mass of the stock TAZ one, but there will be zero bearing deflection. For me that trade off is worth it, but I intend to try and shed as much weight from the carriage parts as I can where it is safe to do so.
