I was wanting to redo my Config seeing all the changes made during testing. In a post it was talkiong about Marlin and RepRap flavors.
I checked my config and have the M555 P2 for Marlin. Seeing the Duet is based on Reprap I was wanting to change my config to RepRap.
So following the wiki link I see that while in the doc its say tp select flavor in GENERAL setting on the configurato now there is no selection and also all the settings talk about mm/ss (Marlin) and not mm/mm (RepRap) if I'm correct.

So is the new config doing a Marlin flavor or a ReRap flavor? I checked bit can not find where to change the flavor.
I'm confused any hekp on how to preceed is appreciated.

I was about to say The tool is for lifting ics , just put it between the legs and pcb., but zapta was faster.

Have to take the card out but its late, but I would have what is default seeing I never controlled or changhed anything.
My camera needs to have the user name and password when I connect fron the D2W, does your camera ask for a user and password?

M574 Z2 S1

Z2 is incorrect. Z2 means "max numeric value of z". Z1 means "minimum value". That is what you should be running.

Note: This has nothing to do with whether the bed is "up" or "down" in relation to the floor... just whether the numbers get smaller or larger.

Tried that but still does not stop.
M119
Endstops - X: not stopped, Y: not stopped, Z: at min stop, Z probe: not stopped

If I use M581 Z2/1 S1 T2 it will do the emergency stop.

@Danal said in Endstop do I need a resistor?:

Wired the way the two switches are wired, they are showing as "Z: not stopped".
That should change to "Z: Stopped" whenever you click either one.

Read above.
Yes when I do trigger the switch and do a M119
Endstops - X: not stopped, Y: not stopped, Z: at max stop, Z probe: not stopped,

Z: at max stop isn't Z: Stopped as you said.

@Danal said in Endstop do I need a resistor?:

Ok still looking for the correct info but from what info i have It should work maybe.

Doing a M119 I get
Endstops - X: not stopped, Y: at max stop, Z: not stopped, Z probe: not stopped

So I would think there are two on the Z axis also because i have a M574 Z2 S1 to define it. When I tried homing i triggered the switch but it did not stop the homing the Z probe did as usual.

Ok one last question, I hope, end stops now working ok took out the R1 and R2 and it works, question now if I use M581 Z2 S1 T0 C0 this will send a M112 and reset the board if I use T1 I would get a pause (which I want ) but this only works while printing?
I didn't want to use a trigger because there maybe a little delay before executing the command.
Am i forced to use T0?

What is your goal? When homing, the printer will stop itself if it hits either of those endstops.

Do you want it to pause if it hits one while printing? Or something else?

They are a backup in case during homing the Z-probe for some reason does not work, so I want it to stop the movement of the bed but without having to reset the printer by recycling it off/on for example. There will be one near the two lead screws.

Thanks Danal and DocTrucker for the help.

@DocTrucker said in Endstop do I need a resistor?:

@Synapsis if you clip the leg like picture you will get a normally open switch, which is a poor choice for a limit switch as it can't detect the most likely failure of a wire breaking or plug pulling out. I remove all of the surface mount components and the outer two connections on the plug behave as normally closed, which is what you want for a limit switch or z-probe.

Exactly what I thought, as I do want NC. Do you have a photo of how you did it?

Thanks for your help.

OK so I see where I was mislead or better misread. On the Wiki Connecting endstop switches I read
"Microswitch
This applies to a bare microswitch, not to a microswitch on a board with a LED.
this i what i didn't see.

Duet WiFi, Duet Ethernet and Duet Maestro: connect the switch between GND and STP/IN. These are the outer 2 pins of the 3-pin connector. Note: this is not the same as on RAMPS."

@Danal said in Endstop do I need a resistor?:

......
Clip out the "NC" connection on the physical switch.
....

Thanks for the fix but one question will it be a NO or NC because if I cut the NC
wouldn't it become a NO?

I have 2 linear guides on a 20x20 profile so I have no flex what so ever only thing to move it the head mount and head. but like you were saved I wasn't saved .

I had tried with a tester and I have a closed circuit until I would press one of the two switches so thought the board had a internal resistor to detect it as NC.

Switch 1 Signal pin goes to signal pin on Duet the common goes to signal pin on Switch 2 which the goes to Ground pin on Duet. So I have it going from ground to signal on the board like I read in a post.
