Using endstop for DC motor
-
Hi,
I connect dc motor to my duet 2 wifi board - through a driver, an external power source and it works great.
The question I have is how can I use one of my endstop switches to stop a dc motor (like a stepper motor) when the endstop switch is pressed?Or other option -
how can I catch an event of "endstop pressed" and after that event execute specific command?Thanks,
Adi -

I appreciate your response very much.
I connect the end stop switch to Y (without a motor)- In addition, I added to sys trigger1.g file that contains the following command: M42 P7 S0.
I also add this line at the end of the config file -
; Custom settings are not defined
M581 T1 Y S1.
Why is the trigger not executed and the DC motor continues to run?
Additionally, I have tried adding M300 in the trigger file to understand if the file is executed when the end stop is pressed, but the beep is not working.
What am I doing wrong? Any suggestions?Thanks,

You have to use a trigger number 2 or greater as in my example.
Trigger number 0 causes an emergency stop as if M112 had been received. Trigger number 1 causes the print to be paused as if M25 had been received. Any trigger number # greater than 1 causes the macro file sys/trigger#.g to be executed.
You can test your trigger macro by typing this in the console
M98 P"trigger2.g"If you still have problems, post your complete config.g and your complete trigger2.g and we'll take a look.

This looks like syntax for RRF2. Surely you are on RRF3.4 now which is far more felxible?
