Double Wade sighted in the workshop
This is a Double Wade extruder http://www.thingiverse.com/thing:6989 being wired up for testing. This assembly saddles across the X axis with one extruder overhanging. With the use of the Prusa-style X carriage http://www.thingiverse.com/thing:6805 with PLA bushings running at 6000mm/min I can now span more of the X axis than I could with the standard Sells-style carriage, and Mendels tend to have more room on the Y axis for me to take up with extra extruder.
Note the twin terminal strip blocks for a head disconnect mechanism. They're clamped around some small nails, and loosening the screws on one side will allow you to remove the whole row of spikes at once like a plug. But this one won't shake loose :)
This is using FiveD/Teacup firmware on a single Arduino Diecemila to control "Custard Slice" (yes I name my RepRaps too).
