Confused regarding RUMBA pinout
March 02, 2019 03:03PM
Hi all!

I have ordered a RUMBA board to replace my RAMPS 1.4 because it has more functions. I have not received it yet, but I thought I'd start setting it up in Marlin.
I wanted to set up auto cooling for the hotend, so that the fan comes on when the hotend temperature is above a certain temperature. I thought I'd use FAN 1 which according to the wiki is on pin 16, but looking in pins_RUMBA in Marlin it's on pin 8. So I started comparing other pins, and they all seem different.
Am I looking at this the wrong way? Is there something I'm missing?

Thanks in advance!

Arduino has its own naming convention for pins.

The pins on the Circuit are physical pins not the arduino pins

See [www.arduino.cc]
