Heatbed output 0Volts

hi friends.

i have an ANET A8, i want Upgrated for Diamond hotend that i can use 3 colors...

today i just installed marlin V1 this version : [github.com] (why the new version of marlin not updated for diamond hotend or dual hotend for ANET A8 ??? we still use the old version )

i use this ARDUINO IDE 1.0.6 realy very old version, brocking all times
[www.arduino.cc]

Anyway i use it for my diamond hotend.

all works fine, auto_level, hotend... BUT NOT THE HEAT END
i have 0°C in LCD, the external mosfet not turn on

BUT if i write this command: M303 E-1 the blue led of mosfet turn on and the bed works fine.

but if i want heat it from LCD or from pronterface button thats not work and i have always 0°C on LCD and 0Volts output D8

i think the pins is disabled from framwork or something...

please help

is there anyway to configure this newst version of marlin to 3d extruders that i can use Diamond hotend ?

yes.

**
* "Mixing Extruder"
* - Adds a new code, M165, to set the current mix factors.
* - Extends the stepping routines to move multiple steppers in proportion to the mix.
* - Optional support for Repetier Firmware M163, M164, and virtual extruder.
* - This implementation supports only a single extruder.
* - Enable DIRECT_MIXING_IN_G1 for Pia Taubert's reference implementation
*/
#define MIXING_EXTRUDER
#if ENABLED(MIXING_EXTRUDER)
#define MIXING_STEPPERS 3 // Number of steppers in your mixing extruder
#define MIXING_VIRTUAL_TOOLS 16 // Use the Virtual Tool method with M163 and M164
//#define DIRECT_MIXING_IN_G1 // Allow ABCDHI mix factors in G1 movement commands
#endif

But I suspect your going to be disappointed..

The diamond is deigned for mixing not really for selecting 1 of 3 filaments.

Since all 3 filaments are in the hot zone, if you don't keep moving them all, then the ones that are not moving tend to get clogged. This is my experience anyways...

NB you always have to have 3 filaments loaded. If you don't when you try and extrude it will extrude from any opening, include any non used inputs. This will make a hell of a mess and take many hours to clean up...
