V4 / Duet2 / KISSlicer / DUAL EXTRUSION Y-bowden FEED and RETRACT?

Post by nurbie » Fri Jul 26, 2019 5:23 pm

V4 set-up as above
KISSlicer Premium v1.6.3
I have dual enabled in the Duet config

Bear with me here, I've had multi-extruder KISS for one day, and this is my first dual extrude.

How the heck do you get the filament to feed and retract?
I just don't know where to start with the whole retraction/feed issues
According to the SMCNC CURA setup you pull the filaments away from the Y-connector 40mm to start.
This would imply that something then tells the machine to push/pull the filaments accordingly.
Help me make a new SMCNC Guide for KISS community!

NO idea if I need to modify KISS, Duet config, or BOTH?

I've got KISS generating a test with short pillar:

Guessing magic has to happen here:

CAN SOMEONE PLEASE POINT ME IN THE RIGHT DIRECTION/S?
There must be some documentation somewhere on how this is achieved as you guys have been doing multi-extruder prints for at least 2years, right?

Hopefully I can lure Hackney(HA!)
get it?
cast,
tug, tug, tug

Thanks in advance!!

UPDATE:
I got the Printer and Extruder settings from SMCNC for CURA, so if I put them into KISS correctly they should work(?)
Can anyone point out the correct KISS locations for these?

per email:
The code in the machine settings(first pic) is where the filament prime, retracts, and at the end retract back so both filaments are above the Y are set up.






I've got this so far:

I also tried putting the second extruder's gcode in the Material Gcode section for the E1 ext material...
Doesn't work
