Need a help with printer.cfg

[quiet mirage]

Recently I updated Klipper on BTT Pi to v0.12... from v0.11... and I have problem with shared_heater section. I am not a software guy. Can someone help me rewrite printer.cfg. For now I used debuging feature for multiple pin usage. I have two extruders and one hotend.
printer.cfg here:

Can you provide what printer you have and what is the actual error message?

[quiet mirage]

I have CR-10 v2 modified and it is erroring on multiple usage of same pin.

Please note that this is a Voron-specific discord. For questions about non-Voron printers, you might have more luck in the Klipper discord.
What is the error that you are getting?

[quiet mirage]

pin P0.24 used multiple times in config

Once the underlying issue is corrected, use the "RESTART"
command to reload the config and restart the host software.
Printer is halted

I'm not sure for your specific case but check out the klipper documentation for. [duplicate_pin_override]
pins:

A comma separated list of pins that may be used multiple times in

a config file without normal error checks. This parameter must be

provided.

I used that but it is debuging feature. It is not for day to day use.

Did you ever follow through on the links I gave you the other day in #klipper_kalico_discussion ?

[quiet mirage]

Oh yeah I tried but didnt understand it.

[digital beacon]

So you found this?

[quiet mirage]

Yes, and looked to the linked page and got lost in coding stuf.

That's not just a list of "coding stuff" though, it's also a list of bloody fantastic Google search terms 😛

So I just change the stepper name? If I get it right?

[digital beacon]

it's a little more involved than that

you setup your first extruder as a regular, single extruder setup

then you setup a [extruder_stepper] for your second extruder

and then lastly you setup your T0 & T1 macros to use SYNC_EXTRUDER_MOTION commands to swap the extruders in and out of action as needed

that zerotheory link I just posted really takes you through it in great detail

(though he's got like 5 extruders, not 2)
