Vertical X Carriage (w/ eccentric nut)

thingiverse

Are you tired of your X-carriage constantly wobbling, no matter how well you adjust it?? I present my new and improved vertical carriage for Tevo Tarantula or any 2040 extrusion. Test printed at 100mm/s. It's possible to see the infill through the wall because I didn't use enough walls. But there is little to no ghost/ringing at all. That was the first time I printed at this speed and achieved this quality. Check also my Y-Carriage!! https://www.thingiverse.com/thing:3999541 List of features and improvements: * 2 V solid wheels on top to better distribute the weight * Eccentric nut on bottom wheel, allowing fine adjustments * BLTouch is mounted behind hot end, this way it remains aligned on X axis and your only concern is Y axis offset. If you have sensor mounted on side, you've realized it's impossible to probe entire bed, printers usually don't have enough room on X axis, the same is not true for Y axis. With my design sensor will be able to probe every millimeter of bed. * Only 3 parts to print. Simple and easy, no supports required * Minimalist and light weight * Requires few hardware and most of them come with printer * Works with radial fang mount List of hardware: * 3 v solid wheels (come with printer) * 3 M5 x 30mm bolts (come with printer). One bolt must be no longer than 30mm or it will hit the BLTouch, or just print spacer or use any spacer or washer you have handy, other 2 might be longer if you want. * 3 M5 nuts (come with printer) * 2 nylon spacers (come with printer) * 2 M4 nuts. You can use t-nuts * 2 M4 x 12mm at least. It's okay to use longer, but do not use shorter. * M5 Washers for fine alignment might be helpful (come with printer) Printing tips: * Endstop bumper doesn't need to be super strong. So, print it as you deem appropriated. * Print belt bracket and main body as strong as possible. I used 4 walls/top/bottom layers. Use a lot of infill too, in my case 80%. * No part needs support, but if you want to add some on the rectangular gap on BLTouch mount, it won't hurt. Everything depends on how well you can print bridges. Assembling tips: * First assemble bottom wheel, here is sequence: M5 x 30mm bolt, 2 washers, v solid wheel, eccentric nut, main body, washer (optional) and M5 nut. * Second assemble endstop and BLTouch, if you are using one. * Now assemble rest as you prefer. I assembled everything to main body, by last I inserted 2 top wheels, holding carriage in place and finally belt bracket. * Sequence of 2 top wheels: M5 x 30mm bolt (or longer), v solid wheels, washer, nylon spacer, main body, M5 nut. BLTouch Sensor Offset X = 0 Y = 28 I'm sorry for not posting pictures for better illustrate assembly process. I was so excited to assemble and test this carriage that I've just forgotten about the pictures. Just let me know if you have any question or some hard time trying to assemble it and I'll do my best to help you. But I believe you'll be fine, this project is pretty straight forward, no secrets! If you decide to print it and install, please take pictures and share with me. Let's help the community. UPDATE 12/02/2019 * XCARRIAGE_Belt Bracket_v2 = Thicker to increase strength, however I don't know if it's necessary, I printed first one for myself and it's holding on for now. * XCARRIAGE_Body_v2 = Distance between BLTouch and hotend increased for those using silicone sock on hotend. If you print first version, silicone sock will touch sensor, and it's better to leave gap between them to dissipate heat. Consider posting a make!
