E0 & E1

[dvsguy]

HI,

Does anyone know if E1 AND E0 on the ramps board can be used with the modified marlin for this project ? I am trying to run them via Pronterface and they are not responsive. They seem to energize when I connect but wont move at all if I send commands or hit the extrude button. DO we need to configure something in the firmware ??? Im stuck !!

Thanks

In order to get E0 or E1 to work, you first need to select which one you'd like to address using the commands T0 or T1. Once selected they can be driven using gcode G0 Exxx.

Also, if you are using more than 1 extruder (i.e. E0 & E1), you will need to configure the number in the Configuration.h file (line #58). To use E1, configure '#define EXTRUDERS 2'.

When I configure EXTRUDERS 2, I get an error like this, I wonder why
