M567: array too long

Timothee Leblond

Hi,

Since I upgraded to version 3.6 of RRF, I now have this error message saying: "M567: array too long, max length = 0" in config.g.

Below is some part of my config.g before the update for a co-extrusion system:

M569 P121.0 S0 D2 ; driver 121.0 goes forwards (extruder 0)
M569 P0.4 S0 D2 ; driver 0.4 foes forwards (extruder 1)

M584 E121.0:0.4   ; set extruder mapping

M563 P0 S"Coflow" D0:1: ; create tool #0
M567 P0 E0.5:0.5; Mixing ratio
M568 P0 S1

Would you know how to solve the error message?

Thank you,

TIM

I thought it could also be a misscommunication with the CAN bus but it is appearing when using M122.
