@dc42 it is probe 0. It is on the main board. P5 equal P8?
Probe 0 can't be configured as P8?

Like i said

It works:

M558 K0 C"zprobe.in"  P5 I0 T18000 F250 H4 A10 S0.005 B0 R0.1
G31 K0 P1000 X0 Y23 Z4.96

M558 K1 C"zstop" P8 I0 F120 H3 T18000 A10 S0.005 B1 R0.2
G31 K1 P500 X0 Y0 Z0.72 ; Set parameters for z switch (if positive, greater value = lower nozzle. if negative, more negative = higher nozzle)

It doesnt:

M558 K0 C"zprobe.in"  P8 I0 T18000 F250 H4 A10 S0.005 B0 R0.1
G31 K0 P1000 X0 Y23 Z4.96

M558 K1 C"zstop" P5 I0 F120 H3 T18000 A10 S0.005 B1 R0.2
G31 K1 P500 X0 Y0 Z0.72 ; Set parameters for z switch (if positive, greater value = lower nozzle. if negative, more negative = higher nozzle)

I don't switch the probe, i just swap P5/P8

@JoergS5 said in Dual Z-Probe Problem 3.1.1:

@JoduWei
The inductive sensor has different Z distance than the microswitch, so maybe the order makes a difference of activation the two sensors.

It is height independent. If i press the switch, nothing happens. If i touch the sensor with metal, both triggered.

Another question is why the microswitch is at X0Y0, at the nozzle position.

Because the switch is besides the bed. The nozzle is touching the switch, to set the z-height. So you can switch Toolheads and nozzles without the need to change the z-offset again.

The inductive probe is just for leveling, z-homing and mesh.

Could it be a bug?

Hey.

I have a problem with my setup. If i use "P8" on the inductive probe and "P5" for the microswitch, Both probes are triggered with the inductive probe, but the microswitch stops working.

If i reverse it, both probes do work. I think that's very strange.

All I can find is "Pnnn Trigger value". But what is it good for?

make machine control modular! It would be nice, if i could remove, add widgets and edit widgets (every widget has its own file)

Oh fk... Ty i've misread the documentation. ty very much!

Hello!

I connected a switch to E0-endstop.
The LED is flashing, if I push the button.

This is what i tried so far:

M581 E0:1:2 S1 T1 C0

M581 E0:1:2 S0 T1 C0

M581 E0 S1 T1 C0

M581 E0 S0 T1 C0

I created the file "trigger1.g" with a M117 command in it.

I does not trigger it...

Edit: Okay, an emergency stop with "T0" works...

Thank you!
I think im going to connect the pi with a "data only" usb cable.

Is there a way to communicate with a raspberry pi via gcode? I want to trigger events. Network, one wir gpio or something else? Is there a "best" way?
