Run both Extruders at the same time

[magicwiser]

So I need to print a bunch of small objects and I was wondering, is it possible to have both extruders print at the same time? That way, instead of the printer constantly switching between extruders, both could run simultaneously allowing me to print two objects in the time it takes to print one by itself. The object is very small so it is physically possible, its just a matter of getting the gcode to make it happen.

Hi Magicwiser,

I've sen this be done in two different places. Each is a little different. I've listed them both below.

Sailfish firmware,
they call it Ditto Printing. You can read up on sailfish firmware here. Sailfish is nice because you simply switch on ditto printing and then it prints with both extruders instead of one as the gcode/x3g file would initially intend. Here is a snapshot of how you would navigate to Ditto Printing if you have a sailfish printer.

There is also the Theta Printer by Github user unlimitedbacon. The Theta is an interesting printer that not only uses polar coordinates (instead of the typical cartesian) but supports printing with multiple extruders simultaneously through the use of their own modified "Bipolar" marlin firmware. See it in action here

Those are the only two solutions that come to mind when talking about literally simultaneous dual extrusion.

I do have a sailfish printer so that will be a lot easier than I anticipated. Thanks
