Filament sensor switch in 4 axis Delta

That's normal when the printer is a delta.

missed that part. thx

but whats the error then?

Error: Z axis maximum must be greater than minimum

He's still using M208 S0, which is the maximum, but he went from -2 as the max height to 0 as the max height. Still makes no sense.

@ander Use M208 S1 Z-2 That sets the low point of the z axis to -2mm below the surface. You'll need a separate line for M208 S0 U1000 to set the max travel for your U axis

Thanks for the help, i tried what you (phaedrux) sayd and worked, i don´t have this error anymore.
Now, the filament sensor switch (it is a regular endstop switch)is connected to pin 4 (E2_stop)in the expansion board.
and is giving me an error:

M98 P"config.g"

Endstop configuration:
X: high end switch connected to pin xstop
Y: high end switch connected to pin ystop
Z: high end switch connected to pin zstop

Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C
Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 1232C

How can i make it work?
here is my last config.g
thanks

thats the wrong name. phaedrux posted a list of the pin names that are valid in this thread

Try exp.e2stop as the pin name.

Hi there
i put exp.e2stop, and my endswitch´s signal wire goes to pin 4 on the expansion side, i see no error for now when i reset the duet. then i tested printing something and pushing and releasing the switch of the filament....the printing continues as normal....so it doesn´t work.
Also, something weird happens with the extruder that i realised. If i set manually for example 200 degrees for the extruder, seems to reach and mantain it very well. but when printing....first reaches 200 degres and then starts autoleveling...and when does it, temperature varies quite a bit, and sometimes gives me temp error due to those oscilations (i´m using a E3D)
thanks

Anyone can help me please?

Sorry I missed your last reply there.

M591 D0 C"exp.e2_stop" P1 E6.0

The underscore shouldn't matter, but try remove the _ between e2 and stop.

The E6 parameter would only be used with the laser monitor. This is a simple switch is it not? So remove the E6 entirely.

You're also missing S1 to enable filament monitoring.

Try this corrected line

M591 D0 C"exp.e2stop" P1 S1

The other alternative is to try enabling pullup resistor by adding a ^ in front of the pin name.

M591 D0 C"^exp.e2stop" P1 S1

If that doesn't work, you can also try P2 instead of P1. I'm not sure what type of switch you have, so try both.

Have you done a PID tuning of the hotend yet? Do you have a silicone sock on the nozzle? Does the part cooling fan blow on the heater block?

Hi there
Yes, i already did the PID tunning, i have an E3D with a sock, but the weird thing is that the malfunction happens only while autoleveling, if there is no temp error after autoleveling the printing goes perfect, the temperature is very stable.
referring to the filament monitoring, i tried like you said and looks like works
