Tried that already.When the heating (usual, not PID) stopped because of

Error:Heating failed, system stopped! Heater_ID: bed
Error:Printer halted. kill() called!

Entering this turned the extruder heater even though by ID I would expect turning the bed on

M303 bed s110 c8

Wouldnt I kind of mess up my pins (voltage etc.) configuration? (Just dont want to damage the MB )

ooops, my mistake, i see that board 301 is a rambo, so try

#define BOARD_RAMBO

I have big Rambo

#define MOTHERBOARD 301

The thing is I can turn the heated bed on via PC or LCD controller without problem, I just cant run autotuning

Which motherboard is defined? E.g. RAMPS1.4_EFF wouldn't have a bed heater.

Hi, so I have been trying to do the PID tuning which came out without trouble with extruder.
When I tried it with my heated bed it threw out :

PID Autotune failed! Bad extruder number

This is what I sent to my printer through Pronterface

M303 E-1 C8 S110

I am using Marlin 1.1.0-RC8
