hello is it possible to have a 5 in 1 extruder for multi color CMYKW with klipper like in Marlin. a reference link here Set Mix | Marlin Firmware
It might be possible to use [extruder_stepper] config sections to control a mixing extruder. I don’t know if anyone has tried.
-Kevin
So I currently have a ZoneStar Z9V5Pro-MK4 with their hotend ZONESTAR M4V6 the 6th Version M4 4-IN-1-OUT color Mix
I want to be able to keep 16 color mixing
* "Mixing Extruder"
* - Adds G-codes M163 and M164 to set and "commit" the current mix factors.
* - Extends the stepping routines to move multiple steppers in proportion to the mix.
* - Optional support for Repetier Firmware's 'M164 S<index>' supporting virtual tools.
* - This implementation supports up to two mixing extruders.
* - Enable DIRECT_MIXING_IN_G1 for M165 and mixing in G1 (from Pia Taubert's reference implementation).

I’m a little confused, did you find a way to implement color-mixing with Klipper? I visited the github link, but I’m still confused on how to implement this. Is this compatible with Klipper? I can’t find a straightforward answer on how to add/use this feature.
Hello, I’m converting to klipper so was collecting info for me to work through once I get my board and start configuring. I’ll let you know what I can work out

Do you had any success, I have a dual mixing extruder in the configuration 2in 1 out.
I can print just with one color with the extruder setup

but every time I change the mixing I got the error
MCU 'mcu' shutdown: Rescheduled timer in the past
This generally occurs when the micro-controller has been
requested to step at a rate higher than it is capable of
obtaining.
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown
it seams that the extruder positions get messed up by changing the rotation distance for the two steppers to implement the mixing.
Any ideas what I am missing and can change?
I solved my problem for mixing, their error had been that I multiplied the rotation distance by the percentage instead dividing it. I now have the following configs, that seam to work:

I now have multiple tools with predefined mixes, where T0 and T1 are the tow colors with one percantage of the other one mixed in to prevent clogging.
And In have macros M163 and M164 to set other mixes.
I had to raise the max_extrude_cross_section to two to not get errors and aborting of the print during the hard color change between T0 and T1 during printing the wipe tower.
I hear heavy moves from the extruder steppers during that change. Any ideas to fix that would be welcome
