Bowden upgrade from prusa p3
Description
Prusa P3 Uses Direct Extruder So The X-Carriage Is Very Heavy As It Holds The X-Axis Motor. Bowden Extruder Seperates The Motor From The Hotend Thus The X-Carriage Is Lighter, Minimizing The Swinging During Fast Returns. This Allows Better Printing. The J-Head Mount Fits To The Existing X-Carriage Screw Holes. I Got The Extruder Parts From Aliexpress As Low As $ 7. You Will Also Need A J-Head Hotend (Preferably With A Cooler Fan) And A Teflon (Ptfe) Tube. When You Have Installed The Bowden And The Hotend Mount, Before Attaching The Tube To The Hotend, Extrude The Filament 5 Cm And Measure The Actual Lenght Getting Out Of The Tube ("E" In Milimeters). Checkout The Steps Needed For 1 Mm Extrusion In Your Firmware Which Is About 700. 700X50=35000 Steps. Then Divide 35000 To "E". For Example If You Measure "E"=120 Then 35000/120=291.667 Just Change 700 To 291.667 In Your Firmware. Also See My Spool-Holder Holding The Bowden Extruder Motor.
