Do you think it is possible to program Mach3 to work in an H-Bot style configurations?

A better link/drawings.  Exact same concept:

It is certainly possible but most existing CAD/CAM software (which produces the necessary GCode) would program separate X and Y movements so you would probably have to write your own CAD/CAM software to take advantage of the 'same direction' / 'opposite direction', combined X-Y stepper rotations.

I don't really see any advantage to using the H-Bot configuration as opposed to conventional X - Y movement but perhaps there is one.

Tweakie.

MeshCAM and Slic3r dont do that kind of interpretation.  This is something I would expect the controlling software/firmware to take care of.

In my case the H-Bot has huge advantages. Hot compartment for 3D printing.  Steppers don't like to function in 100C environments.

As far as Mach3 goes... I found the "formula axis correction" which makes me think it is possible.  But I can not seem to get it to run. Even a simple X+1 function does not seem to effect jogging. Looks like I might have to use an Arduino as an in-line mixer to do the necessary math.  I hate putting extra stuff in my control path. :-(

Any one?
