    My question does not concern the subordinate axis.
    The question of correcting the perpendicularity of the axes.
    For example, in Mach3, this is solved through formulas.Click image for larger version.

    Ok i see. I did not even know it existed in Mach3.

    Answer is No. But any software can do this. So it could be corrected in CAD.

    if we are talking DIY CNC here, if its correctly constructed that will not be an issue. Epoxy leveling or surfacing. Mounting one rail against straight edge. With the help of same long straight edge and 2 precision squares mounting the second rail. If care is taken straightness and parallelism less than 0.05-0.02mm could be achieved even in a big router, which is absolutely enough. I have mounted 1000x500 machine with even better precision.

    At the end of the day its a cheap controller. But as i said you can skew the drawing in any CAD then send it to CAM and machine.

  4. All clear. In any case, I already ordered ddscv1.1 4 axis for the experiment.
    Editing in the CAD program is not suitable for a variety of reasons, so this function is in all serious machine control programs, even in an amateur like a mach3. Precise adjustment of the axes perpendicularly incommensurably faster and more accurately done programmatically, especially in those cases where it is already very difficult to do mechanically.
    Of course, not everyone needs this function.

    You widened the discussion to "all serious machine control programs" and thus made industrial products part of the discussion

    You made industrial products part of the discussion so that doesn't matter ;-)
    You think that's too expensive? You're not a Model Engineer are you? :D

  6. I agree. You're right.

    Here on this machine I have a problem with the perpendicularity of the x and y axes. On some tasks this did not suit me. I solved the question in a minute, in the mach3. And with the utmost precision. I do not imagine how much time I would have spent on the alteration in order to achieve the desired perpendicularity of the x and y axes.

    Any software to correct the dynamic variable geometry of the commercially made (in Devon) machine that I have ? My machine just does not cut the mustard. At least not accurately !

    Does the controller in question handle master and slave drives on a single axis? Can it use a homing switch on each of these with defined offsets to allow the gantry to be re-squared each time you home it? That seems like a better approach which allows for the possibility that the perpendicularity is not built-in when you have a moving gantry with separately-driven ends. I agree that the ideal, and certainly in the case of milling machines rather than routers you would expect X and Y axes (and Z, of course) to be built perpendicular.

    I'm following this discussion because I'm interested in where these cheap dedicated controllers are going. At the moment I'm happy with Mach3/PC/motion controller but I can see a day when a standalone box might be the way to go.

    It was made in Devon - designed to cut the cream for cream teas but barely capable of cutting the scone...

    It's a bodge for wonky machines which shouldn't be necessary, machines should be built square ;-)
