Linear Bearing X Axis Carriage for ToM
by MakeALot, published
I found some LMB6UU (SW06UU in US) linear bearings for Â£4.50 each, so tried them as a direct replacement for the bushes on the Y Axis based on thing thingiverse.com/thing:9114 by splod, they worked so well that I created an X Axis carriage for them and here it is if anyone would like to try it.
People in the UK can get them from worldofcnc.com/products.asp?recnumber=167 or get them from eBay ALOT cheaper
I printed the ABP version and found a miscalculation in the end bolt holes; these are corrected in the _FIXED versions of the STL and SCAD files

Can you you also put up solidworks format? I got LM8UU an 8mm rods, this would be perfect to replace those darn busshings.
the file is like you said for LM6UU. can you provide stl for the LM8UU ?
another question.... would this be possible to print on a ToM because of the size? it is actually th
e same size as the printbed right...?
I'm having a hard time finding these bearings on ebay or grainger. Are these the right parts: http://goo.gl/CfZfU I can't find any sw06uu, only sw6uu.

Insert 6 @ 12mm M3 bolts into the supplied HBP part and affix base.
Press 3 linear bearings into the carriage, you may put zip ties round each if you prefer, mine is running happily without.
Insert X Axis belt into slot and slide it down until it is just touching the bolt, gently tighten the bolt so that the belt is just held, but not pinched.
On the Y Axis, I removed the right hand rod and the bushes, inserted the bearings up to the grove and replaced the rod, I let them bed in for a couple of prints before I added the spot of glue to fix them more permanently.
