Hi there!!! the setup is complete!! hopefully everything goes fine with this configuration, i just moved the 4th axis putting the conector in the extruder´s driver and works fine so far. i put the pictures here to see the mechanical configuration, and if you have any questions for the development of the firmware just let me know.!

Hi, i just checked it and it was this, thanks for the help,you guys are giving a really nice support

Hi there!!!
a bit late but here goes my setup:
https://www.youtube.com/watch?v=ToBLN7YHWt4

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"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
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
U: high end switch connected to pin e0stopWarning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C

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

config(9).g

Thanks for the help.
The screen now works thanks to your advice
the filament sensor value is changed to 0 and is not giving any error but i don´t know yet if works properly (how can i check that?)
the macro error....you were right, i didn´t send the m500 yet because i just put a new duet and i´m trying to put it to work.
I changed the z -2 to z0 and i still have the same error.
this is what i see now after sending M98 P"config.g"

This is my config file:

@Phaedrux said in Filament sensor switch in 4 axis Delta:

M98 P"config.g"

Thanks for the help.
Yes, my firmware was 3.0 and i uploaded to 3.1.1 but i had some trouble after doing so.
now the screen shows "connecting" the whole time and it doesn´t work .
from the duet web control it works normal.
this is what popped out when i send the comand you asked me to send:

i don´t know why but an error pops out when i try to update duetwificonbined.bin
i updated duet2and3firmware3.1.1.zip and worked.

config(7).g

Hi there!
I would like to connect a regular filament sensor switch to my duet wifi with firmware 3.0.
My machine is a delta printer with 4th axis that carries a flying extruder on the 4th axis.
My E0 stop port is used for the effector´s switch and the E1 stop port is used for the aditional axis´s endstop(U axis).
My idea was to use the expasion board´s pin for the filament switch(E2´s stop pin).
But i don´t mannage to make it work.
I would also like to know what changes in the web control when you activate this function so i can test properly if works.
This in my config.g :
config(6).g

This is my last config file:config(4).g

i updated to firmrware 3.0 and the temp sensors read well but still having issues with the autolevel sensor working in the opposite way

Hi there!
i´m updating my prusa hephestos2 to duet and i´m trying to make the original autolevel sensor work but the duet keeps saying the sensor it is already activated.
when turning on the duet already says P1000 altho it is at 100 mm height, when i aproximate a metalic thing to it it changes to 0 so it detects well.
I am going crazy trying to change it to 0 when is high but i can´t do it.
also the hitting sensors show 2000 degrees, i´m using the original ones of 95k
config(3).g I´ll put my config file so anyone can help me please.
this is my setup:
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.03beta3 (2019-03-25b6)
WiFi Server Version: 1.23
Web Interface Version: 1.22.6

It worked very well!
Thanks for the excelent service!!

Sorry i missunderstood. i made the change you suggested and still makes non printing moves very slow

I don´t know why but the config file was on the right of the picture i sent.
i just removed the U parameters in the home section, and the u axis doesn´t go back home anymore
