Robo3D Direct Drive Extruder MOD
Description
Ok I Have Used This For Years Now And It Works Very Well With Absolutely No Issues. Most Parts Are Reused. I Highly Recommend To Use Reversed Design So That Filament Puller Faces You Instead Of Back Of The Printer. Lower Center Of Gravity Will Give You Room For Speed Increase Without Loss Of Quality. Less Weight Will Minimize Whiplash Effect Responsible For Creating Bulging Corners. Less Distance For Filament To Reach The Nozzle Will Help With Flexible Filaments. I Now Included 3 Carriages. If You Dont Want To Modify Stock Carriage, Print One Instead (Print In The Orientation Provided). Bearing Hole Size Is Standard (15Mm) But Because Not Every Printer Can Print Exact Size, I #3 Sizes Of Carriage With 0.2Mm Increment In Diameter. Carriage Has 2 Loops For Eazy Belt Attachment. No Need For Any Zip Ties Etc. If You Print 15.2Mm Carriage And Its Too Tight, Print 15.4Mm. Using Round File Can Help Bearing To Go Inside Easier Without Having To Reprint. 15Mm Carriage Is The Original (Almost Guaranteed To Be Too Tight) 15.2Mm ( In My Case It Worked) 15.4Mm (For Those Who Still End Up With Too Tight Of A Result.)
