Hi,
I developed a new shield for arduino due RURAMPS4D.

http://3dtoday.ru/blogs/svs0724/ruramps4d-ramps-for-adruino-due-the-pilot-shipment-available-for-zack/

I tried different firmware, and on Mk4DUE 4.3.2 encountered a problem:
The HotEnd0, controlled from pin 13 arduino, will not turn on. On other firmware everything works.

Here is the pinout file of the board
1410.h

Can anyone suggest what might be the problem?

Maybe a safety feature, what does the hot end thermistor read at room temp?

code shows a MINTEMP 5 is required... so make sure it reads 5 or more

Tehrmistor read 23C, when choosing a dummy thermistor (998), the hotend does not turn on either.
In repetier firmware and marlin 2.0 it work.
There is an assumption that pin 13 in MK4Duo is reserved for something, but under that I can not find

Pin 13 is connected to the onboard led on Arduino.
Not sure, but maybe this is the reason.
