duet 3 endstop wiring

[A Former User]

the ground and input pin of the io0-8 headers

although you may want to refer to https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Hardware_Overview#Section_IO and use the io headers that doesn't have other functions you may need

[Dad003]

so middle pin and the one next to it , it what i have right now but my endstop always show as triggered in the duet control , when i try to home axis move but do not hit the switch

[A Former User]

normally open or normally closed switch? and how is it configured?

[Dad003]

they are close switch that open when hit , duet control show then has triggered , one on each axis , at the low end excepted the Y axis

here the switch him using


[Dad003]

i found something when i hold the limits switch it show as not trig erred anymore and when release it show back to triggered what parameter i show inverse ?

next to it could be ioN.out or ioN.in so pin 2 is input and pin 3 is ground to rule out ambiguity.

also how is it configured in config.g?

edit: ah, its configured connected correctly then. I think you need to invert the pin with the M950 command, but someone will probably confirm.

[Dad003]

SO WHAT SHOULD THE M950 LOOK LIKE ? SOMETHING LIKE THIS ? IN THE WIKI THERE NOT REALLY AN EXEMPLE FOR THAT KIND OF STUFF

M950 Jnn "IO_0" C"IO0.IN" !

[Danal]

Endstops directly define their pin in m574, no M950 is used.

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

[A Former User]

maybe thats just for the zprobe, and you can invert the endstop with a ! in m574 ? idk and caps locks doesn't help..

https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3

[Danal]

Z Probe also directly defines its pin, and yes, ! and ^ work per usual:

M558 K0 P9 C"^io4.in" H9 A5 T6000 S0.02 ; Z probe BLtouch - Set the height of the bed when homing G28. Combined with content of bed.g as invoked by G32, levels bed. Also used for Mesh.

[Dad003]

@Danal

when i try this G code it tell me the pin is not free and nothing happen

[Danal]

Then you have something else in your config.g that defines that pin, before what you are trying. There are no default assignments.

Did you remove the M950?

[Dad003]

this is what i have for config file

try
M574 X1 S1 P"!io0.in"

and so on

[Dad003]

my endstop are assigne to io_0 , io_1 and io_2

[A Former User]

note the exclamation point before the pin name, should invert the pin so its active when pressed instead of the other way around.

thank you , that solved my problem !

and another problem gone , now i need to figure out why the bed heat so slow

[Dad003]

so here another development after finally having the limit switch in the right state , trying to home the axis , X will move and do what need to be done , Y will move but not hit the switch or ram into the switch without stopping and say it home and the Z axis will move like 10mm and nothing else without even ever getting close of the switch

him using the basic g code from the RRF Config tool, i even copy pasted the X home code that was working and switching the coordinate and axis and it still doesnt work
