Y Axis Linear Rail Mounts

Last crawled date: 6 years ago
Want to do a linear rail conversion on your y-axis? Sure thing!
This uses two 400mm mgn12h linear rails with 3 carriage blocks attached to the bed, set up like the prusa i3 mk3. The ones I bought were for use with M3 hardware, but there will be larger versions for larger hardware up shortly.
After testing this for about a month now, it really isn't a print quality upgrade, its more of a quality of life upgrade for some, and a "because I can" upgrade for others. I usually print about 100mm/s so maybe it'll help with increasing speed, but i was doing that with rods as well.
You'll need:
4 of the printed linear rail mounts
8 M5x16 bolts, these were extras/spares from the re duplicator build
8 of the t-nuts or htnaj5 nuts or whatever they're called; something to insert into the extrusion and tighten down using an m5 bolt.
12 M3x? bolts for the carriage blocks (or m4 or m5, whatever yours are) preferably if you can find m4, use that since that's what is already being used on the stock setup
4 more m3 screws and 4 nylock nuts for bolting down the rail to the mount
possibly a dremel, since the holes on the carriage blocks and the bed holes personally did not quite line up for me.
patience. lining up these rails is tricky, and any deviation will be noticeable due to the higher precision that comes with rails.
