Error compiling if extruder count == 0

[pixel3design-hub]

As I want to use MK for Laser CNC Engraver/Cutter, I don't need the extruder stepper driver or extruder heater. I need to configure like that: X & E0 => dual X drivers Y & E1 => Dual Y drivers Z => Single z Driver

I'll use pins 42 & 44 for TTL PWM and Laser ON/OFF.

But when I turn to 0 the extruder count, Arduino throw me an error.

// This defines the number of extruder real or virtual

define EXTRUDERS 0

// This defines the number of Driver extruder you have and use

define DRIVER_EXTRUDERS 0

Can You provide a configuration for CNC works? Thanks and keep up the good mood.

Put still extruders and extruder drivers to 1 then do not use it. Nothing happens..

OK. And about duplicate stepper signals? I got 2 motors on X and others 2 on Y, just one on Z. Motors are 1.7A per coil, so putting them in parallel is not viable.
