Hi Everyone! First of all I want to thank the quick response and the good vibes of this forum.

Now my question:

I have an Arduino Mega 2560 with RAMPS configured for two extruders (MOTHERBOARD 34) and I have connected an endstop to the Y_MAX_PIN (pin 15) my intention is to somehow link the Y_MAX_PIN endstop to stop the second extruder (E1) when endstop click.

I was looking at the part pins.h Arduino Mega pin assignment Modifications making some with no luck.

Is there any advice you can give me on how to accomplish this? Thanks in advance.
