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

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

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

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

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

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