Voron 2.4 two mcu options

[BrianL]

Is anyone running two main boards (excluding a toolhead board) on their 2.4?

I am looking at the BOM and I have a Duet 2 wifi sitting here with 5 steppers (original) - unfortunately one short for the motion system. I don't have a Duetx expander for additional steppers and they are difficult to find now the Duet 2 wifi is discontinued and the cost of that expander is up with a new 8 stepper board where I have seen them. I am reluctant to ditch the board as it was uber-expensive when I brought it and the specs are still very acceptable (TMC2660)

I was wondering if there is any performance / reliability / quality hit for running one board on the 4 bottom steppers and a separate smaller board (SKR Mini E3 etc) board for the steppers on the gantry using klipper. I was under the assumption that one board is required for the full motion system but technology is moving so quickly these days

I think you answered the question yourself when you mentioned the toolhead board, its the same concept.
You should be fine adding the SKR

I run 2 skr mini e3's for xy and z and canbus for the print head - works well.

Thank you very much for this.

Hi Paul,
I am currently building a V2.4 350 in the same configuration as you mentioned: 2 btt e3 v3, btt canbus, orbiter extruder and TAP. I just started with installing Klipper and flashing the board with the printer cofig but am not sure how to run with two boards and maybe your help could save me some hours of trial and error. What Version of e3 do you run and would you mind sharing your config file as reference for my build?
I would greatly appreciate that.
Best wishes,
Perotin
