More heater for a tool in copy mode

CorvoConV

Good morning.
I'm designing and building a printer with four tools in a dual IDEX configuration. I've created a new gcode to enable and disable copy mode, but I get an error if I assign more than two heaters.


;Configurador del modo copia M940 Cx

if(param.C == 1)
    M563 P4 S"Copia cuadruple" D0:1:2:3 H1:2:3:4 X0:3 Y1:4 F0:2:4:6
    G10 P4 X0 Y0 U{-(move.axes[3].max/2)} V{-(move.axes[4].max/2)} S0 R0
    M567 P4 E1:1:1:1
if(param.C == 0)
    T0 P0
    M563 P4 D-1 H-1

Is there any way to be able to manage all 4 heaters at the same time?
Thanks

@CorvoConV What hardware and firmware are you using? Send M122 and post the response.

Presumably you're using a Duet 3 Mini 5+. Currently the limit for the Mini 5+ is 2 heaters per tool, see https://docs.duet3d.com/User_manual/RepRapFirmware/RepRapFirmware_overview#firmware-configuration-limits

@dc42 may be able to increase this; I'm not sure why it's only 2 compared to other boards.

Yes, i am using the wifi mini, i forget to see that limit

I will manually set the temperatures in the starting gcode of the slicer.

Thanks.

@CorvoConV @dc42 has increased the MaxHeatersPerTool from 2 to 8. This should be available in the next firmware release. https://github.com/Duet3D/RepRapFirmware/commit/e31003fdcb3b3ffaf33d8a3150e32c88bdf83e6d

I think no one had ever asked for more!

Nice, thanks for all.

Dual IDEX sounds really interesting, I saw a brief glimpse of your printer on Instagram and it looks really good and congratulations on your award.

You might want to consider upgrading to a 6hc board - so that you can run different gcode on the two gantries in parallel.

Would be interested in finding out more about your design - such as the kinematics your are using, bed probing, head alignment etc.
