Has anyone created a special dual extruder x carriage for ditto printing?

Has anyone created a special dual extruder x carriage for ditto printing? I would think an option where you can separate and extend the dual extruders easily would make sense to maximize the possible build space only when you need to?

For what kind of printer… Ditto is built in to both Marlin and Sailfish firmware, which pretty much covers most printers available out there with dual or three extruders.

How would I use ditto with Marlin? Never figured it out

@William_Steele didn’t realize. I was asking about the prusa i3 but I guess I can modify another if I have to.

@Abc_Def I know it works with repetiur. Haven’t tried Marlin

How would I tell it to do ditto? It’s gotta be a slicer setting…

@Abc_Def no its a firmware

I’ll look into it

Ah, that’s right, it’s Repetier firmware that does it, not Marlin. But it should also work on any machine that runs Marlin as well.

If I remember correctly, it’s M280. It takes a single parameter, S0 for off or S1 for dual.

So m280 s1 enables ditto?

Well… here is a Marlin fork that does do Ditto printing.

It uses the M420 command.

Just found that also. I’ll eventually upload that. For now I have to fine tune the printer beforehand. That will help a bunch when I do orders of many small pieces

@Abc_Def Yep!
