LUCAS extruder - finally a really universal extruder
Description
Update August 14Th - Please Check Out Version 2: Http://Www.Thingiverse.Com/Thing:428312 While This Is Still Working Very Well (The Servo Version At Least), The Improvements Of The New Version Are Worth It! Update July 29Th - I Have Been Having An Amazing Feedback From You, Lots Of Amazing Suggestions To Improve The Design. Thank You Very Much! Unfortunately I Haven'T Had Free Time To Work On It As I Wanted, So The Project Is On A Temporary Halt. I Have Updated A Couple Of Files Here, Correcting Some Minor Mistakes, And I Have Also Uploaded The Complete Sketchup File; It Might Be A Little Messy, But I'M Sure You Can Find Your Way Around It. If Not, Just Shout! Update July 5Th: - See Updated Instructions Video (With English Subtitles: Http://Youtu.Be/-H-Zzxgwx2S) Importante: If You'Re Using The Servo Version (Or If You Don'T Use Bed Auto Leveling At All) You Don'T Need To Print The X-Carriage, It'Ll Probably Fit The One You Already Have, Just Check If The Standard 50Mm Holes Match. Universal Extruder - This Is My First And So Far Most Important Reprap Project. I Grew Tired Of Replacing Extruders And Disassembling Lots Of Parts Every Time The Nozzle Got Clogged Or I Had To Swap Material. So, Finally Here It Is, An Extruder To Suit All Your Needs: Can Be Used With 3.00M Or 1.75Mm Filament And With (Almost?) Any Hotend (To Be Verified). The Concept Behind This Project Is Actually Simple: I Designed Small Pieces ("Bits", As I Call Them) And And Adaptor Inserted In The Main Extruder That Can Be Replaced Anytime You Need. Just Open The Idler And Change The Filament Width; Open The Front Lock And Change The Hotend. I Am Also Uploading The X-Carriage Designed To Work With The Bal (Bed-Auto-Leveling, See Below) Version Of This Extruder. I Also Added To This Concept Everything I Always Wanted In An Extruder: A Quick Release For The Filament, A Belt Tensioner (Not On The Extruder, But On The X-Carriage) And A Bed Auto Leveing Switch Without Any Servo: When The Nozzle Touches The Bed, The Extruder Rotates And Activates The Switch. This Is Very Experimental, I Don'T Expect It To Work Flawlessly, But It Is Here To Be Developed. So, This Is Still A Work In Progress. I Haven'T Even Tested It In A Real Life Situation, But I'M Making It Public Anyway So That You Can Help Develop It. I Really Thing This Project Has A Great Potential And Could Become A Standard For Extruders. As I Write This Text I'M Printing The Second Prototype, Where I Corrected Some Problems, And I Plan To Put It To Work In A Couple Of Weeks. I'Ll Upload Photos As Parts Get Ready And Assembled. Last But Not Least, This Isn'T Actually 100% *Mine*. It'S A Remix Of Several Things I Found Here, Put Together In This Project; See Sources For More Information. Thanks, Hope You Enjoy It.
