duet2wifi + duex5 on firmware 3+ problem

axillent

Hi,

I'm using the following in config.g for my tronxy corexy X5S with two independent Z motors:

M584 X0 Y1 Z2:9 E5:3:4:6
...
M574 Z1 S1 P"zstop+duex.e5stop"

etc. i do have 2 independent Z motors + 2 independent endstop sensors
it is working as expected just after powering ON
but a few steps after, mostly on the following print motor 9 do not stop on endstop duex.e5stop

what do i do wrong?

Firmware version? Should be 3.1.1. Send M115 to verify.

Can you also post your config and homing and bed file?

m115
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-05-19b2

Would it be possible to change things around in order to put both motors and endstops on either the duet or duex?

Under "Firmware limitations" https://duet3d.dozuki.com/Wiki/Duet_3_firmware_configuration_limitations it is stated quote

"Endstop switches connected to the main board cannot control motors on an expansion board. This is planned to be fixed in release 3.2.0."

I'm not sure if the the Duex 5 is considered to be an expansion board in this context, but if it is, that would explain why that configuration doesn't work.

@Phaedrux not simple but possible for sure
is it a solution or a try?

axillent

@deckingman i saw it
but first - it is about duet 3 is'nt it?
the second i do have right motor + endstop both on duet and left motor + endstop both on duex

etc. i do not trying to stop motor connected to expansion by endstop connected to the main

@axillent I think it's worth a try.

That firmware limitation applies to Duet 3 only.

Endstop inputs on a DueX board are more easily affected by noise than inputs on the Duet, so it would be better to connect your second Z motor endstop to the E0 or E1 endstop input on the Duet.

@dc42 thanks, i will try
is it because of noise between sensor and the board or about noise between duex and duet?

i do plan to use laser sensors, at least 2 of them
can i connect laser sensor to the duex?
the plan was to use E0/1 endstop inputs
