Quick fit carriage system
Description
__Description__ This Is A Quick-Fit Carriage-System Which Can Be Equipped With Different Heads Including A Fdm Head, A Mill-Head, A Custom Laser Head And Other. Changing The Head Takes Only A Few Seconds. All(!) Electrical Contacting Is Realized By A Sub-D Connector. Stability Is Provided By An Easy But Effective Clamping Design. Design Your Own Head Based On The Provided Custom-Plate. Turn Your Prusa Into A Zmorph. __Other Fitting Parts:__ I Made Other Fitting Plates For Various Other Tools. I Keep Them In Separate Pages To Not To Clutter This Page. You Can Find A List Of All Fitting Parts Here: Http://Www.Thingiverse.Com/Search?Q=Lukie80+Quick+Fit+Carriage The Extruder-Plate-Thing Is Compatible With This Fan Duct: Http://Www.Thingiverse.Com/Thing:1392612 And The "Fan-Duct-1" From Http://Www.Thingiverse.Com/Thing:1275203. __Contacting__ The Electrical Contacting Is Realized By A Sub-D Hd 26 Connector Which Offers Enough Pins For Different Heads. A Typical Single-Extruder Head Requires 14 Pins Which Leaves The Rest For A Leveling Probe, A Servo, A Usb Or I²C Connection And Additional Power Lines. It Even Offers Enough Pins For A Dual-Head Setup. __Mechanical Compatibility__ It Is Designed For A "Geeetech I3X" (And Its Mk8 Extruder) But Should Be Usable For Any Prusa I3 Variant. It Is Made For A X-Rod Separation Of 45Mm And A 2Mm Gt2 Belt And Fits Bushings/Bearings With A Diameter Of 15Mm (Default) Or 16Mm (Select Proper Model File). The Width Of The Base-Carriage Is 86Mm, The Height Is 78Mm And The Depth Is 31Mm. The Extruder-Plate Is Designed For A Proximity Sensor With A Diameter Of 18Mm. (Let Me Know If You Need Another Diameter.) __Effort__ Be Warned, Soldering Of All The Wires Takes Some Time. The Wires Have Also To Be Placed Carefully Within The Provided Limited Space. But You Will Be Rewarded With Quick Head Change And Faster Nozzle Change. __Some Design Decisions I Made__ - Clamping Without Screws -> Faster Change, But There Was No Room For Screws Anyway - Bushings/Bearings Are Held In Place By Friction - Carriage Width Of 86Mm -> Enough Room For The Cables/Connector/Belt - Z-Min Actuator (The Upper Horns Of The Plate) Is Located At The Changeable Plate -> You Can Tune Z-Min By Adding Or Removing Material From The Actuator - All Connections Are Open If Nothing Is Attached -> You Have To Simulate The Hotend Temperature Sensor By A 100K Resistor (You Have To Simulate Your Distance Sensor Too If You Use One) - Mill Head Fits A Rotary Tool And Not The Flex Shaft -> The Weight Of The Rotary Tool Helps Milling __Parts Required__ - Base Part: Female Sub-D Hd 26 Connector, M3 Screws 3X 20Mm , M3 Nuts 5X, M3 Washers 4X. - Extruder Part: Male Sub-D Hd 26 Connector, M3 Screws 2X Approx. 6Mm, M3 Nuts 2X. (Optionally: If You Want To Use A Z-Probe In Series(!) With The Z-Min-Switch You'Ll Need Some Electronics Parts Given In The Drawn Schematic.) - Mill Part: Male Sub-D Hd 26 Connector, M3 Screws 2X 10Mm, M3 Nuts 2X. A 100K Resistor As Thermal Sensor Simulation. (Optionally: If You Want To Use A Z-Probe In Series(!) With The Z-Min-Switch You'Ll Need A Short Wire.) - Custom Plate: Same As Mill Part Plus Your Custom Things. __Let Me Know If You Encounter Problems Or Need Changes.__ __Updates:__ - Added V2 For "Plate-Extruder-Mk8" Which Should Hopefully Not Sag. It Has An Additional Supporting Structure And Two Holes For 2X M3 50Mm Screws Which Should Prevent Bending. - Added 12Mm Sensor Option For "Plate-Extruder-Mk8" (Plate-Extruder-Mk8_With_Support_V2.Stl) - Added V3 For "Plate-Extruder-Mk8" Which Has An Additional Bracing Which Will Cost You ~4Mm Of X-Movement But Prevents Sagging Of The Part.
