duet 3 endstop wiring
-
what pin to use on the endstop connector for a 2 wire micro switch since there 5 spot ? i readed the wiki but doesnt seem to find a clear answer . so i need help ,
-
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
-
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
-
normally open or normally closed switch? and how is it configured?
-
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
-
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.outorioN.inso pin 2 is input and pin 3 is ground to rule out ambiguity.also how is it configured in config.g?
edit: ah, its
configuredconnected correctly then. I think you need to invert the pin with the M950 command, but someone will probably confirm. -
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" !
-
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)

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

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

this is what i have for config file

-
my endstop are assigne to io_0 , io_1 and io_2
-
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
-
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
; homeall.g
; called to home all axes
