Hi,

I'm currently making a 3D printer and was wondering if I could use mach3 to connect the extruders.  I want it to have dual heads and can't seem to figure out how to connect the second head.  If it was a single head I'd just connect it as a spindle.  But with 2 heads, I'm not sure what to do.  Can an axis be 'turned on' without any Gcode? Can Mach3 be configured for dual spindles?

Any insight is appreciated.

Space...... out!

Maybe you could use M3 for one spindle and M4 or M5 for the other

If this only for a 3D printer

You will probably have to manually update your Gcode for that.

Or any Mcode can do if you

The axis as spindle as toggle will get way too messy.  Just use M3/M5 for one head and M8/M9 for the other.  Of course you'll need an interface relay tied into your controller but they are out there at a reasonable price.
Hope this helps,
