Hello everyone! I didn't post anything so long.... >_< Ok, let's fix it!
This is my new carriage for Y-axis. Now i'm using MGN12 rails and MGN12H carriages, instead wheels. Also I placed them to bottom of profile - this solution much better for me. It's looks pretty well now ~_~
Where I bought rails:
- 2 x MGN12 Rails (390mm length,holes by 7.5mm on both sides)
- 2 x MGN12H Carriages (With "H" in end, also I recommend you to take +1 pcs, it will very helpfull, if you lost some balls from carriages)
Before installations, I grease carriages by Castrol LMX
To assembly of one carriage you will need:
4 pcs - M3x35 screws (or M3x40), for assembly main parts
2 pcs - M3x25 screws, for bearings
4 pcs - M3x10 srews, for mount MGN12H carriage
2 pcs - M3 selflock nuts for bearings (if you haven't them, you can use usual nuts)
4 pcs - M3 usual nuts
10 pcs - M3 washers
4 pcs - M5x10 screws, for aluminium profile
4 pcs - M5 square nuts
4 pcs - M5 washers
To mount each of rail I used 4pcs of M3x10 screws with T-nuts.
This models for printing with plastic without shrinkage. So if you want to print this models with ABS, you'll need to set horisontal-compensation property in your slicer, because ABS has shrinkage.
I recommend you to print it with PETG. This plastic strong and haven't shrinkage, so you can just print this models how are presented.
I used current endstop, just moved it in other place, like on photo bellow
