QU-BD One Up and Two Up Z-Bearing Alignment Spacer Upgrade
Description
This Spacer Will Upgrade The Qu-Bd One Up And Two Up Printer So That The Distance Between The Threaded Z-Screw And The Smooth Z-Rod Are At The Correct Distance From Each Other, And Better Constrain The Linear Bearings To Reduce The Sagging Of The Gantry. Installing This Upgrade Will Reduce Or Eliminate The Z-Banding Caused By The Binding Of The Vertical Motion Of The Gantry Due To Binding Of The Z-Screw And The Nut. By Stiffening The Alignment Of The Linear Bearings To The Gantry, This Upgrade Also Improves The Alignment Of The Gantry To The Z-Rods. This Reduces The Vertical Skew On Printed Parts. Designed For The One Up, As I Don'T Have A Two Up To Test - I Have Now Uploaded A Two Up Version Which Is Experimental And Unverified, But I Believe It Should Work. If Someone Can Give It A Try, That'Ll Be Great! Be Sure To Read The Instructions! **Please Like And/Or Collect This Thing If You Plan To Add This To Your Printer, And Please Post Your Make! Thanks!** --- Interesting In Buying A Set? Read On... A Number Of People Have Commented On Not Being Able To Print Their Own Spacer, As They Don'T Have A Working 3D Printer. Unlike The Sometimes Missing Base Plate For The Extruder, You Can Actually Assemble Your Printer Without This Part And Start Using It. It'S What I Did -- The Z Screw Is A Little Bit Bent Because Of This, But Not By Very Much. However, If You Still Would Rather Have That Part From The Start, I'Ll Be Happy To Print Them For You - Please Visit Http://Toybuilderlabs.Com/Qu-Bd-One-Up-Z-Bearing-Alignment-Spacer-Special/ For Details.
