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

You can do the retract/load either in the slicer tool change scripts, or in the Duet tool change files. If you do it in the Duet tool change files, it should work for all slicers.
