Y carriage with 3 point heatbed leveling

thingiverse

It's a Prusa, Mendel, RepRap type Y carriage with 3-point leveling of the heatbed. The needed things are shown in pictures plus four LM8UU bearings and eight PVC cable ties. If you use caps for LM8UU, additional sixteen M3 nuts and sixteen M3x16 bolts are also required. The source file in Autocad (2010 or higher version) is uploaded for laser cutting. I plan to make one or two of these next month. The two holes behind the ones for my belt caps are compatible with this belt holder, which can be used as a belt tensioner - http://www.thingiverse.com/thing:552485. 09/12/2015 Hi again! Here are some updates. I've made one of these and added some new pictures. There was a mistake for the M6 bolts; they should be M6 x 60 mm, not 40 mm as shown on the picture. With luck and pushing, you may use M6 x 50 mm. It's very easy to level this carriage. However, one of the bad things is that you must have 530 mm of table movement on your Y axis or 265 mm from its center. So it's not compatible with standard Prusas; they're too small. You'll lose a lot of print area on Y if you use this thing. The other bad thing is that you'll lose at least 30 mm from your Z print area - it's inevitable. Personally, I don't have a problem with this issue, but I don't know about you. So I'll leave this design for my bigger Mendel-type projects and also for my Delta and box-type ones. I'll do my best to add another design with three leveling points moved on the sides, so they don't mess with front-back movement and Y print area. 09/25/2015 Well, Version 2 became a whole Y axis system! A short video is available at https://youtu.be/0rnlMLoOqgU. The source file for it has been added. I've also added built-in support for LM8UU caps in case anyone wants to use them. I think this is the final version, and I won't make any changes anymore.
