Belt redesign for FT5 using F625ZZ bearings
Description
Who Has Had Issues Already With The Gt2 Pulleys On Y And X? I Did! I Replaced These Small Bearings Already Several Times And Decided To Finish That By Using Large Ones. In This Design I Used F625Zz (16Mm X 5Mm With Flange). I Mounted Them Both On A 25Mm Long 5Mm Bolt With Flanges To The Outside (See Pictures). What Did I Need : 2 Pulleys For The Y-Axis. New Supports For The Y-Steppers (I Wanted To Get Rid Of The The Whole Melamine Piece Under Both Y-Belt Channels - No Worries About The Length Of The Rods : See Picture) Supports For The Cablechain On The Right Side. Whats Special About The Pulleys : While Still Warm, I Screw The Bolt In And Create As Such A Thread That Holds Quite Good **The Left X-Pulley : 2 Pieces Now**. I Made A Separate Support For The Bearing To Allow Nicer And More Accurate Printing One Could Also Mount The Y-Pulley Supports Upside Down And Leave The Melamine Base. I Replaced The Bed Support By An Aluminium One Made Of Standard 2Mm Thick Profiles. Modified Cablechain Support Items : 50Mm Instead Of 60Mm Everything Mounted And Tested ... See Http://Www.Thingiverse.Com/Thing:2045169 For A Revised Version. In The Revision Belt Tension Adjustment Is Done With The Pulley Instead Of The Stepper
