So I have laser cutter. And I am thinking about buying a control unit (this one, to be exact).
But my concern here is the following: If the input DXF file contains splines, they will be converted to lines (G01) and arcs (G02 or G03), since these are all the entities G-Code has.
Since have absolutely no knowledge about motors or controlling them, the question is as follows:
- Does the control unit from the link do the same? Does it convert DXF to G-Code?
- If yes, is there a control unit that would quide my laser cutter over a spline from the DXF and NOT on some series of lines and arcs?
- This webpage says that only Z axis is controlled with PID. Why? How are other axis controlled. Does this mean I could in general choose between PID and G-Code?
