The right M574 command: 6 axis Delta Printer + Smart Effecor

tkln

Hello community,
I have a Delta with 6 motor and 6 endstops. Each tower has two motor. At the moment the motor are coupled 1:2 (Tower 1), 2:3 (Tower2) etc. with each other.
The homing of the tower (6 motors) works.
I'm workin with a 6HC board (48V, Motor, Endstops, Touchscreen) and a EXp3hc board (24V, Smart effector, Hotend, Extruder Motor, Thermistor).

M584 X0.2:0.3 Y0.0:0.1 Z0.4:0.5 E1.0

Now I have problems with the smart effector. If I request a G31, I get a G31

Error: G31: Invalid Z probe index

and at the star of the Printer I get

Error: M558 output Port not supportet on Expansion board

How do I have to name the z-probe?

; Endstops
M574 X2 S1 P"io3.in+io4.in"                              ; configure switch-type (e.g. microswitch) endstop for high end on X via pin 1.io1.in

Programming Z probes connected to expansion boards is not yet supported. For now you need to temporarily connect the Smart Effector to the main board if you want to change its sensitivity. I've logged this issue: https://github.com/Duet3D/RepRapFirmware/issues/815

open Support programming Smart Effector sensitivity when the effector is connected to an expansion board #815

@tkln the issue is there in the error. M558 has failed due to configuring an output port not being supported on a CAN board. Either remove the output port as its not strictly needed to run a smart effector (unless you're changing sensitivity) or connect the smart effector to the mainboard.
What firmware version are you running on the mainboard and the 3HC?

@tkln Please send M98 P"config.g". The response will show if there are any errors in your config.g.

You should be okay to run a type 8 probe from an expansion board, but as @jay_s_uk points out, I can't remember if the second pin (which is only used for programming sensitivity) is supported on a CAN connected board. Try:

M558 P8 R0.4 C"1.io0.in" H5 F1200 T6000         ; set Z probe type to effector and the dive height + speeds

It may also be that you don't need the CAN address for the second pin, because it is implied from the first pin, so it is causing the error (M950 is like this); try

M558 P8 R0.4 C"1.io0.in+io0.out" H5 F1200 T6000         ; set Z probe type to effector and the dive height + speeds

I'm checking with @dc42 if the second pin is supported, and how it should be defined.
