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.

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 .

DocTrucker 16 Apr 2020, 08:57

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.

Thanks Danal for the reply I have a Duet Wifi the switches are attached to the Z end stop switch which Index 2.

I'm having problems with my end stop not triggering. I have a X and Y plus a Z probe, but because in the past a couple of times the Z-probe wasn't working the bed would crash into the nozzle. So I want to use a two mechanical switches in series attached to the Z end stop seeing its free as NC. The switches are in series and go to ground and signal on the board. I set in config.g M574 Z2 S1 (S1 seeing its NC) then I have M581 Z2 S1 T2 to do an emergency stop (still have to figure T out). Anyway in Machine-Specific I have Z not triggered which is correct problem is when I press the end Stop it does change state to YES. On the board I see the LED for the Z end stop dims but does not go out completely like X and Y do. So do I need a resistor on that NC end stop to get it to work?

Thanks

Here is a Youtube video you can try. video
When you try the wireless method you do keep the phone close to the camera?

thanks Phaedrux yes I did see it but had tried a different test for max extuder speed. Just finished do that test and I was too high so now its almost right. Will try some new test to see what happens.

Jen55 I think your math is good but for sure 420 is too fast seeing the Hermera has a hotend like the Titan Aero only it is more direct.

Thanks Jen55! I'm doing the tests at 220°. I would have thought the Hermera would go a bit faster. My problem is in the benchy test that in the bow there is some sagging (droops) as you can see in the photo.
! .
Agree its not the best color.

Fan is on during the test print of the benchy.

I'm trying to tune my max extruder rate on my new Hermera. It will start to extrude with a width of 0.4 mm but the it will grow to 0.75 mm
I started with G1 E50 F120 and in steps went up to G1 E50 F460. here are some photos.!

The first two are at the lower speeds while in the third and fourth, which are at G1 E50 F420 the is a loop which is always consistent and when it does the loop there is a clicking noise.
Not wondering if this is the Hermera or something strange in my setup.
Thanks for the help.

@Nuramori no I went to the console to be honest.

@jens55
You nailed it started with 260 the 275 then 280 a it got to 280 and was stable put 285 and it would'nt go over 280.

@DocTrucker Using PLA I only use 205° more or less I set 285° just in case I wanted to ever get it hotter.
This reason I noticed is because I needed to heat tighten the hot end and it said to use 285° for this, if not I doubt I would ever had noticed.
