All the software recommended in here are for a 4axis system. Is there one for a simple 2Axis system ?

*UP/DOWN = Y
*LEFT/RIGHT = x - foam block placed on this plane.

mach3 will work for simple movements and there is probably a way to get it to work for the 4 axis stuff but It would take a little thought to make that work.

I tried Mach. The conversion process takes a 2d drawing as a weird zig zag puzzle... got me all puzzled. lol

any two axis software or controller can run a foam cutter, you would need to either slave the left and right side axis together, or its sometimes possible to run 2 drivers on the x and y axis. mach would work great, but you would probably want to use another software to create the g code. there are other reasons to stuck with software made for foamcutting, for example, venom, your zig zag is the software choosing pretty much at random what small area it is going to cut next, unlike a mill or router, the machine cannot just lift the tool and move to another spot. once it starts the wire is always in the foam traveling to each area to be cut out. what a foamcutting software will do is allow you to number each area, and create a start as well as a depart on each closed area. this allows the wire to cut one half of each area on the way in, and cut the other half on the way out, this makes for less unwanted cuts in the surface. Ill post a couple pictures in a few minutes to illustrate.

pics, one shows the random zig zag that the computer chooses, the other shows a planned cut path. the blue color is cut when the wire is heading in from its start point, and the green is cut on the way back to the start. the outer rim is only one color since it is the final cut with its start and depart in the same location, it could have just as easily been part of the green half of the cut. normally the wire would have to start from the outside and go in, not start in the middle and work outward for the obvious reason that the wire cant start already inside the foam. For some reason I couldnt get the drawing to move from having its center at 0,0,
