Allowing Print Head Beyond Printable Area for Dual Extrusion - Is It Possible?

[Benjamin4456 0]

Hey all,  I'm working out the details of an Ender 3 Chimera setup and so far this Cura situation has been my only bump in the road.

 

On the Ender 3 the x-gantry has the travel for the Chimera hotend to reach the edge of the bed on both sides with both nozzles, however, in Cura it of course limits the x-width thinking that this is not the case.  My first thought was to just oversize the bed in the printer config, but then the prime line would end up off the bed, not to mention it's more of a Band-Aid than a fix.  Sure the prime line can be moved, but I'm still wondering if there's a proper way that Cura supports this.  Is it possible for Cura to see the whole bed as printable area even with dual extrusion?  Said another way, can the axis travel limits be defined separately from the printable area?

 

I've been cruising through Cura settings and so far haven't found anything that does the trick.  It seems like something that would exist, I just can't find it.  Open to any thoughts you folks might have.
