R3D Flsun I3 Mod Kit Part 1

Description

<H1>R3D Flsun I3 Mod Kit</H1> **Long Term Use Update** I'Ve Been Using The Mods In This Kit And From Parts 2 And 3 Ever Since I Made Them Back In Early 2017. I'Ve Had Very Little Issues With The Printer And It'S Pretty Much A "Turn On And Print" Printer.. No Issues With Bed Leveling After Disabling The Stepper Motor Timeout Setting In The Firmware. It'S Been A Reliable Printer Every Time I Use It From Fine 0.04 Layer Height Prints To 0.8 Layer Height Vases Up To 120Mm/S Print Speed. Also Along The Way I Added A Magnetic Flexible Build Plate Which Has Been A Nice Improvement In Convenience.. As Well As A Set Of Tmc2208 Drivers Which Are Super Quiet. **** This Is Part 1 Of 3 Of My Collection Of Mods For The Flsun I3 Printer. This Is The Most Important Mod Out Of All Three Parts. These Mods Will Help Stabilize The X And Z Axis And Fix Z Wobble And Most Layer Line Issues. It Does Require Hardware Upgrades, But They Are Relatively Inexpensive. Use The Photo With The Ruler As A Guideline For Spacing. Also, There Is About 2-3Mm Of Space Between The Leadscrew And The Motor Rod Inside The Coupler. **Don'T Forget To Change The Z_Max_Pos To 255Mm Like I Did And Have Your First 250Mm Print Stop At 220! :) ** *Update 5/24/2017 - Added Photos Of A Recent Print And For The Dimensions For The Anti-Backlash Nuts *Update 6/29/2017 - Printing Smoothly At 100Mm/S. With All The Mods In This Series, I Can Easily Go Up To 120Mm/S. Https://Youtu.Be/6Qq_Azx2F1E?T=16 <H2>Notes On Printed Parts: </H2> **Top Rods Holder** -- These Are The Top Brackets Which Are Modified From The Original To Have A Tighter Fit And A Hole For The Leadscrew. **Lead Screw Wobble Brackets** -- These Use Skateboard Bearings To Keep The Leadscrew In A Fixed Axis And Aligned With The Top Rods Holder. **Xz Carriages Fitted For Anti-Backlash Nuts** - Left & Right -- These Will Fit Anti-Backlash Nuts And Igus Delrin Bearings. You Can Use The Steel Linear Bearings But You May Have To Sand The Holes Out A Bit. **Xz Carriages Original Fittings** - Left & Right -- To Fit Steel Bearings And Regular Nut. **Z Limit Switch Mount** -- Modified To Fit Over The Lead Screw Wobble Brackets And For Better Stability. **Hotend X Carriage** -- Adjusted Fan Mounts For Better Alignment. Modified Belt Holes For Easier Mounting. Modified To Fit Igus Bearings. <H2>Required Hardware To Go Along With The Printed Parts:</H2> * 2X 370-400Mm Lead Screws. I Used 400Mm Because I Couldn'T Find Any 370. * 2X Skateboard Bearings * 2X Anti-Backlash Nuts - See Photo For Specific Dimensions. * Fiberglass Reinforced Belt (Optional But Highly Recommended) It Will Have Less Stretch Over Time. * 4X Igus Delrin Linear Bearings (Optional) You Can Use The Original Steel Bearings. I Have Included The Original Xz Brackets So You Don'T Have To Use The Anti-Backlash Nuts But In Order To Get The Full Benefit, I Recommend Using The Modified Version. ===================================================== <H3>Links To Kit Series</H3> **Part 1** : Http://Www.Thingiverse.Com/Thing:2307152 - Fixes Layer Shifting And Wobble - Highly Recommended **Part 2** : Http://Www.Thingiverse.Com/Thing:2307161 - Replacement Parts For The Acrylic Pieces That Can/Will Crack Over Time. - Optional But Recommended **Part 3** : Http://Www.Thingiverse.Com/Thing:2307169 - Cosmetic And Recommended Mods To Improve Overall Look And Safety. - Optional *List Of Original Sources That Were Modified* Wobble Bearing Bracket - Http://Www.Thingiverse.Com/Thing:2008919 Flsun Delivered Parts
