DoomMeister's, Kuehlings Sells/Prusa X Ends
Description
I Am Busy Renovating/Improving My Sells Mendel To Use Linear Bearings, Smaller Pitch Belts And Proper Lead-Screws And I Noticed A Few Things. 1) Prusa (Iteration 2) X Ends Don'T Fit The Sells Design, The Distance Between The Z Axis And Lead-Screw Is 30Mm Not 29Mm. I Only Noticed This After Printing A Set :(. As An Aside I Think The Belt Driven Z Lead-Screw Is A Much Better Design Than The Dual Motor One And Will Be Sticking With It. 2) There Are A Great Many X Axis Designs For Trapezoidal (Acme) Lead Screws, But They All Use Metal Nuts. As Evidenced By My Old Z Screws, And The Small Pile Of Iron Fillings At The Bottom Of The Z Screws On My Orca This Is Not A Good Idea. 3) The Prusa Scad Sources Are A Pain In The Bum To Edit. With This In Mind I Have Modified Jonas Kuehlings - Improved X Ends For Prusa With Clamped Rods To Accept A Plastic Lead-Screw Nut Which You Can Machine Or Print. The Z Nut Press Fits Into The Holder (Use An 8Mm Bolt To Help) And Is Held In Place With A Key Bolt. I Have Split The Z Nut Into Another Thing As I Prefer To Gpl My Things And Base For This Design Is Cc-By-Sa Files Posted For Both The Sells And Prusa Mendel.
