    G02/03 G-code to drive four-axes foam cutter

    I have a four axis foam cutter (X, Y, A & B) using Mach3. I am using inkscape to create the G-codes (using the g-code plugin). The codes typically contain G01 (linear translation) and G02/03 (arcs). The G01 commands can be edited to drive the four axes separately, but the G02/03 commands seem to only accept two axes. There doesn't seem to be a way to specify all four axes to follow the same arc. Obviously, I can slave the A&B axes to the X&Y on Mach3 and run it as a two-axis system, but this disables the ability to create tapered structures. I was wondering if there is a workaround to this problem. One option is to replace the G02/03 commands with a series of G01 commands. I could write such a script, but I don't want to reinvent the wheel if there is a software or script that will already do that. A second option is if I can tell inkscape to not use G02/03 commands, but that doesn't appear to be a choice on the plugin. Any suggestions would be appreciated.

    Re: G02/03 G-code to drive four-axes foam cutter

    By default, the G02/03 commands make arcs on the XY plane. If you want to do them in another orientation, you'd need to give a G17,G18, or G19 command. Here's an explanation: https://infosys.beckhoff.com/english...g02g03.htm&id=

    I'm not sure what you're trying to do, but Inkscape is a 2D program, and any G-code it makes will be limited to 2.5D at best. To take advantage of your 4-axis machine, you might want to look into 3D CAD CAM software.
