duet 3 endstop wiring

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

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 ?

@Dad003 said in duet 3 endstop wiring:

so middle pin and the one next to it

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)

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

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.

M574 X1 S1 P"!io0.in"

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

Please reset the homing files to the ones the the configurator generated, and post them here along with your current config.g file.

@dc42 ok,

MY bed should go down hit the limit switch and back up but nothing happen when i try to home that one but it will move when using control

Dad003

Here something weird , i was trying to tune the heat bed and started homing Y actually worked like intended i didn't change anything in the config when it wasnt working 15 min earlier
