Clearance betwene x an y axis

Hello I’like to some reverse mpcnc and build clone of mpcnc in OpenSCADA. I’m going to replace 608 bearing with smaller and cheaper 626. I need to know clearance between pipes in F-roller and F-rollerM. I load stl file into freecad to meashure distance, I’ve just got around 37-37.3 mm. Some body help me?


there are already exists mini version of mpcnc like builds

I know about these but they isn’t compatible. With origin mpcnc I’d like to make only carriage.

It does not matter, the corner sets the distance that matches with the gantry.
