KISSlicer select/deselect code dual extrusion

[Lawrence LaRocque]

Hello all, I have been using kisslicer for little over a year now with a prusa i3 single Extruder. I currently do not have any select or deselect code for this printer since it was a single. I am currently building a dual direct drive prusa i3 and needed some input for the select/deselect codes. Can you post some examples or maybe some things to have in there. I want to try to make this so I don't have oozing and use the wipe pillar and have a wait for cool down and wait to warm up when a tool change occurs. I could figure it out eventually but I wanted to try to get a head start on it. Thanks again for everyone's support and the kisslicer community is amazing.

Hello,

I copied attached scripts somewhere and use these on Felix printer. X80 Y200 heating position is for that extruder goes first straight to prime pillar. Lines keep leaks during heating and help start the machine.

Heating and cooling works OK. on Felix but filament backtrack behave strange. gcode looks right but backtrack doesn't work right, probably problem in Felix firmware.

Is there somebody who got deselect filament backtrack work properly on Felix?

Thanks for the reply. I'll use this as a starting base. Still piecing everything together. Got the firmware ready to flash the arduino just need to solder the stepper drivers and put everything together. Thanks again

I am fiddling, too, with "filament backtrack"... but I believe that your solution

G92 E0
; retract filament 2 mm
G1 E-2 F8000
G92 E0


..Isn't working due to some weird behaviour of G92.

I am playing with this approach:

T<EXT+0>
G1 E<E-5> F1000         ;suck 5mm of feed stock
G92 E0                  ;zero the extruded length again

M104 S<TEMP>

...but KS seems to be using NOT the current extruder for calculations.

Best Regards

Davide, I read your other post in another thread, the name leaves atm, but i will follow the development on that, I am currently using marlin from before the auto level was added.  Can't quite remember the date but i checked my backups and it was before june 2013..  I am currently in the process of building a new prusa i3 with a bowden with autolevel using a rc servo and rebuilding my current prusa i3 with direct drive dual extruders.  I am in the process of transfering all my settings from the old marlin to the new marlin in prep for the builds.  I will keep you informed on any developments.  Life seems to always get in the way of hobbies :P  Kids, school, work, all seem to run together and then there is sleep but that is sacrificed for printing :P
