Remix of Colorizer components for Direct Drive extruder on E3

thingiverse

A massive thank you to the original designer! These parts are designed for the E3 with standard Ender Direct Drive addons. as opposed to the bowden tube job! The pen cap is 80mm to avoid conflict with the tray. The arm has the cutouts for the wheel bolt and also allows 20mm further to get the pen past the motor. The carrier has a skirt to make it collect the pen more easily and also has the tip cut out to allow the extended position of the carrier to fly over the bed bulldog clips if you use them. You will still need to remix the tray to allow the filament to pass unhindered in everyday use! (i just cut the centre out with a dremel). My study of the retraction is worth paying attention to below! Turn OFF retraction in ALL pen extruders. Turn ON retraction for Extruder 1 and set to normal anti stringing level Ignore the Extra Retraction setting. Rem out all inserted retraction and feed lines that show G1 F1500 E(- or nothing for return of filament)(Value set in box) when inserted into the gcode. ***OR EDIT THE SCRIPT*** *****NOTE even with the value set to 0 or 0.001mm it still retracts more than 75mm of filament (must be a quirk of the Marlin firmware? maybe?) so you have to rem out the inserted lines ****** For me however modifying the script to still insert the lines but put a rem (;) in the output so they are ignored is best simple bet for now! There are two points you need to add this semicolon! Hope this research helps others with Direct Drive. Regards. Graham.
