Yes I am using the Sonic Pad. Those errors are probably mostly because I broke the hotend thermistor, but that’s righted now. I am newer to the space so I apologize for not thinking of what version my hardware is capable of.
@DrumClock I find your setup interesting.
Is the “Shared Pin” setup your method to mimic the deprecated “Shared Heater” option that was in the [extruder] object?
-James
Yes, I discussed it with a friend and it is probably the best way
to solve it when the “Shared Heater” is no longer functional.

I have an old A10M with a mixing extruder. Following the above I got it working with a extruder and a extruder stepping object.
I defined T0 and T1 like above for single color prints. I added a T2 macro with a mix of 50% from both filaments and even added a M163 gcode macro to enable other mixing settings. I had not been able to find those online, so I am happy to provide it here for others:
[gcode_macro T3]
gcode:
SET_EXTRUDER_ROTATION_DISTANCE EXTRUDER=extruder DISTANCE={8.437 * 0.5} # 50%
SYNC_EXTRUDER_MOTION EXTRUDER=extruder MOTION_QUEUE=extruder # Add e0
SYNC_EXTRUDER_MOTION EXTRUDER=extruder1 MOTION_QUEUE=extruder # Add e1
SET_EXTRUDER_ROTATION_DISTANCE EXTRUDER=extruder1 DISTANCE={8.231 *0.5} # 50%
[gcode_macro M163]
gcode:
{% set rot_dist0 = params.ROT_DIST_0|default(8.437)|float %} # define in default the rotation distance of the extruder
{% set rot_dist1 = params.ROT_DIST_1|default(8.231)|float %} # define in default the rotation distance of the extruder
{% if 'P' in params %}
SET_EXTRUDER_ROTATION_DISTANCE EXTRUDER=extruder DISTANCE={ rot_dist0 * params.P|float / 100}
SYNC_EXTRUDER_MOTION EXTRUDER=extruder MOTION_QUEUE=extruder # Add e0
SYNC_EXTRUDER_MOTION EXTRUDER=extruder1 MOTION_QUEUE=extruder # Add e1
SET_EXTRUDER_ROTATION_DISTANCE EXTRUDER=extruder1 DISTANCE={ rot_dist1 * (100-params.P|float) / 100 }
{% else %}
# default 50% mix
SET_EXTRUDER_ROTATION_DISTANCE EXTRUDER=extruder DISTANCE={rot_dist0 * 50 / 100 }
SYNC_EXTRUDER_MOTION EXTRUDER=extruder MOTION_QUEUE=extruder # Add e0
SYNC_EXTRUDER_MOTION EXTRUDER=extruder1 MOTION_QUEUE=extruder # Add e1
SET_EXTRUDER_ROTATION_DISTANCE EXTRUDER=extruder1 DISTANCE={rot_dist1 * 50 / 100 }
{% endif %}
you need to change the rotation distance values to match to your printer in T2 and M163

the above is just the concept. With it a 50% mix can be set by m163 P50.
But the usage of M163 and the following M164 is different. e.g.:
M163 S0 P84.08
M163 S1 P15.92
M168 S0
I will change the macro soon to be able to work with standard M163 and M164 sequences.

Is there any way to configure TMC drivers with the extruder_stepper? That way I can still have them in stealthchop.
Literally created an account to say thank you so so much for this!!!
I’ve managed to get a 2in1 out non mixing extruder working on one of my Vorons using 2 Mobius M4 extruders with this 
An picture to show the very first print, happening as I type!
Love the 3d printing community to much, THANK YOU!! Totally renewed my love for FDM printing!!

A post was split to a new topic: Mixing Extruder
hey there, for a single hotend 2x1 what is the expected behavior of SYNC_EXTRUDER_MOTION EXTRUDER=belted_extruder MOTION_QUEUE=extruder and STEPPER_BUZZ STEPPER=extruder? I am trying to sanity check things and can only move the first extruder. Is there a different command for extruder_steppers for buzzing?

Remove the “extruder” from your extruder_stepper config. This will cause the two steppers to run together.

Stepper_buzz I believe is just:
STEPPER_BUZZ STEPPER=belted_extruder
Or
STEPPER_BUZZ STEPPER=“extruder_stepper belted_extruder”
I’m not home to test it out, so I don’t remember.
-James
I tried both and neither worked. I will try the buzzer command tomorrow. It’s weird though because extruder0 moves no matter the T0/T1 state being able to buzz ex1 will be helpful.
Did you remove the “extruder:” value from the belted extruder config?
Both are moving simultaneously because both steppers are synchronized together.
Yes, I removed the extruder assignment, no dice. The thin is that both extruders would not move in that config, so I’m thinking something else is up. I’m away from the printer now, I will update when I can.
Hello Here is my current working config (still Bata working on calibration) for an BTT octopus with a 3 in to one head , three BTT runout Encoder switch three Bondtech extruders , Duel Z steppers and Closed loop X and Y steppers . Enjoy and I hope it helps anyone who needs it.

Hi there.
I stroggle to get multicolor Prints working with PrusaSlicer 2.6 and Klipper.
I have a BiQu 2in1 Hotend.
All the Settings are like in this Post but at the second colorchange before the Printhead moves to the whipetower i still get: “Unable to infer active extruder stepper” because of the Set pressure advance setting from the slicer in the g Code
Help please!
Regards
Tim

Here is my current working config for a 3 in 1 out… with a runout encoder. I hope it helps in any way…
printer (2).cfg (20.4 KB)
@Snakn1 : If you want to upload a config file, then
-
Do it as file using
-
Or as preformatted text using
You can find both in the editor’s tool bar.
As plain text, it looks quite meshed up and due to deleted spaces, it can cause some trouble.
Which Slicer are you using?
The printer.cfg looks quite the same as my one, but i still are not able to print multi color with PrusaSlicer.
OK first I want to say my config is correct yet… I notice that the T0 is the only one that is trigging the encoder runout switch and pausing. For some yet unknown reason the T1 and T2 does not trigger. The display will show empty like it should but it does not pause. So that being said the tool switching and over all printing is good. I have used simplified 3D (before the upgrade V4) and Cura all with out mods. All my old gcode’s work and un-mod new one from both works on this config.
