Duet Wifi endstop showing N/A in active low

MrIvorVra

After upgrading the complete firmware to 3.01my Duet says that the endstops are not connected.
Clicking the endstop manually lights up the light on the board and on the endstop.
I changed nothing on the board after the upgrade.

Setting the M574 to S1 shows the endstops as actually connected but then the signal is inverted

M119
Endstops - X: no endstop, Y: no endstop, Z: no endstop, Z probe: at min stop
That's with M547 set to S1

What are the M950 definitions for these? And/or, just post your whole config.g, please.

MrIvorVra

My apologies it's set to S0 not S1.

config.g

Just for reference, these are working for me on Duet3 hardware:

; Endstops and probes

M574 X1 S1 P"io1.in"                      ; Set homing switch configuration X1 = low-end, S1 = active-high (NC)
M574 Y1 S1 P"io2.in"                      ; Set homing switch configuration Y1 = low-end, S1 = active-high (NC)

Yours look like this:

; Endstops
M574 X1 S0 P"xstop"                                      ; configure active-low endstop for low end on X via pin xstop
M574 Y1 S0 P"ystop"                                      ; configure active-low endstop for low end on Y via pin ystop

Which is very similar. Two things might be making a difference:

S0 v S1. I have physical switches that are "Normally Closed". This should be S1. Are yours normally closed or normally open?
The pin definition. I take it you are a running on a Duet 2?

If so, per this guide, everything looks correct.

In summary, I don't see anything wrong with your definitions except S0/S1, which you can try both ways, once you can see the switches status

When you say "upgraded to 3.01", what RC? I highly recommend the very latest, that is DSF 2.1.2 and RC10. The traditional commands

sudo apt update
sudo apt upgrade

Will get you there.

MrIvorVra

S0 will give out

M119
Endstops - X: no endstop, Y: no endstop, Z: no endstop, Z probe: at min stop

S1 will give

M119
Endstops - X: at min stop, Y: at min stop, Z: at min stop, Z probe: at min stop

When you go to Machine-Specific if you set S0 it Says "n/a" in the triggered column

the switches I use are normally closed that use a signal pin

as for firmaware

With RRF 3.01 you must use S1. If the enstop inputs are active low, invert the pin. For example:

M574 X1 S1 P"!io1.in"

MrIvorVra

Thank you.
This solved it.
