Duet3 problem sensor homing, not happen in Duet2

FBG

Hello everybody!
i am user of a lot Duet2Ethernet boards with Expansion Breakout.
All is ok.
Now I start with my first Duet 3 Mainboard 6HC v1.01A with severals Duet 3 Expansion Board 1XD and with raspberry.
Everything was config perfectly and all works well, now the WebInterface is really fast!!

My unique problem is:
When I do homing...90%times while the axis (indifferent) move to find the sensor...the axis stop because think that the sensor was triggered....
It always starts to move and when it moves a few cm it stops...as if the sensor had been found!!

I use a simple sensor switch, tested with NC or NO. I use a good brand wires crossed shielded.

I use this config:

; Endstops
M574 X1 S1 P"!io3.in"           
M574 Y1 S1 P"!io7.in"

Also I tested:

; Endstops
M574 X1 S1 P"^!io3.in"           
M574 Y1 S1 P"^!io7.in"

Also I has tested without raspberry and I test with 3.3.0 and 3.4.0 firmware version.

Today I install a duet2Ethernet, with 3.3.0 and 3.4.0 firmware.
Everything is absolutely perfect 100% times.

What happen?? Any idea?

Remove the !

@phaedrux I think that I don't explain well....
I must use ! if the sensor is in NO, and not use if the sensor is in NC..
As I said, I tested in NO and NC, with same results

The problem is not that the start to move in opposite direction...start to move in right direction but WHILE is moving to find the sensor...STOP! as the sensor has been triggered! but the sensor is not triggered!

@fbg What does M119 show? It should be untriggered when the endstop is unpressed.

FBG

@stephen6309 If I send M119 without press any home sensor:

Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stopped

If I send M119 with X sensor pressed:

Endstops - X: at min stop, Y: not stopped, Z: not stopped, Z probe: not stopped

Same result with others sensors

Everything is normal....

Ideas?

Is the switch actually functional?
Do you have continuity on the wiring?

@phaedrux The sensors are news and perfect, also I changed for a new and happen the same.

Remember @Phaedrux IF I test with a duet2Ethernet ALL works properly.

Today I checked that show in "Objet Model->sensors->endstop", if when the axis move and stop the triggered say "yes"...
I can confirm that when the axis stop before touch the sensor I don't see TRUE, all time say FALSE.

So, if say FALSE all time, because STOP???

Firmware problem?
Duet3 Hardware problem?

Post your config.g and your homing files. Perhaps you have the homing move shorter than the axis length.

This makes me think you've wired it incorrectly. Photo?
