I printed in parts and can now print the first color but my retraction isn't working right still. 1st color goes all the way through and prints but does not fully retract from my direct drive orbiter extruder. What adjustments do you suggest? I have tried adjusting (G4 S10 ; <<---- INCREASE VALUE (S = Seconds) TIME IF IT DOESN'T UNLOAD FROM THE Y ADAPTER) but it still won't unload. its almost as if the extruder itself needs to retract. here is my complete tool exchange Gcode.

I think both my cams are broken so its not fully engaged to drop filament properly. Im going to print new ones. Do you have the top cover piece available to download? mine has layer separation around the screw holes. I use the included bracket so not screwing directly on these holes but the filament lines fell out. Maybe bad prints in my kit?

Hi Bill, I think this fixed my programming issues, but now I'm having a problem where the setup doesn't move the filament to the extruder or it moves 2 filaments at the same time and jams in the y piece.

I adjusted the speed down since the orbiter v1.5 is geared 7.5-1. Also I'm down to 55 retraction to cool and went extremely down in speed for the final retraction to help cooling but I only get successful tool changes 25% of the time. below is a snip of my Gcode. What adjustments do you suggest? G0 E-20 F3000 ; quickly retract the filament to shape it G0 E-10 F500; slowly allow it to cool G0 E1 F1500 ; blob elimination ; back to tip size G0 E-20 F3000 ; quickly retract the filament to shape it G0 E-10 F500; slowly allow it to cool G0 E1 F3000 ; blob elimination G0 E-10 F3000 ; quickly retract the filament to shape it G0 E1 F3000 ; quickly ram the filament to shape it G0 E-10 F3000 ; quickly retract the filament to shape it G0 E1 F3000 ; quickly ram the filament to shape it ; back to 1.8 constriction G0 E-15 F3000 ; quickly retract the filament to shape it G0 E-40 F10; slowly allow it to cool ; turn the fan off M107 ; this printer has the fan in the way, so turn it off ; retract it back out of the extruder

My adjustments didn't really help. What do you suggest I try next?

G0 E1 F4000 ; quickly ram the filament to shape it ; back to 1.8 constriction G0 E-30 F4000 ; quickly retract the filament to shape it G0 E-40 F100; slowly allow it to cool ; turn the fan off would this mean cooling is at E-70? the -30 and -40 added together?

I saw another post about tuning retraction for the cooling with tip forming. I have an ender 3 with a direct drive orbiter extruder. 80mm for cooling may be pulling it out of the short tubing between gears and the v6 I have. I wonder if I adjust to 60mm will help the forming. testing now. Also, wow you are fast with responses!
