Flexible coupling ~ 5mm stepper to 3/8" lead screw
Description
*Important* You Must Turn Down The Stepper Current For Your Z Axis Motor Before Using This Coupling (If You Print It In Pla). On The Standard One/Two-Up, The Stepper Currents Are Set Too High By Default And As A Result, The Steppers Get Very Hot. This Can Actually Allow The Coupler To Deform Enough To Become Unusable, So Be Sure You Turn Down The Current! Here Is A Flexible Coupling I Designed For My Two-Up 3D Printer. It'S Design Allows It To Be Printed Relatively Quickly, It Has Support For Up To 3 Set Screws (Although Only 1 Is Absolutely Necessary) And It Has Plastic Spiral Pieces In The Center To Allow For The Screw To Pivot If It Is Not Perfectly Centered. Requires At Least 1 M3 Nut And 1 M3X8Mm Or Longer Bolt . Notice That If Your Z-Stepper Gets Hot During Use, You May Be Required To Use All 3 Bolts. If You Have Just One And It Gets Too Hot, It Could Force The Coupler To Permanently Deform. Using 3 Screws Will Prevent That Problem. Fully Compatible With The One/Two Up With The Stock Gantry Or With Stefanburgers 3D Printed Gantry.
