Topic: All bearing Y axis conversion
I have had a pain adjusting the belts to remove backlash on the Y axis. If too tight the motor stalls, if too loose backlash. I think tight is the way to go but have encountered other problems. Motor stalls, rear axial starts squeaking even with grease, rear axial slightly bends down from motor belt tension and forwards from tension from front idlers.
My solution is to go full radial ball bearings. I saw someone already did it on the rear (6x13x5 flanged bearings). I plan on adding qty of 2 (5x8x2.5 flanged) bearings to each of the new idler brackets. and add a printed pillow block with qty 2 (6x13x5 flanged) bearings in the back to help keep the rear axle from flexing under the tension.
I have designed and printed the pillow block and also modded the new idler brackets to accept the bearings. Just waiting on delivery of the bearings to test and work out any kinks.
