    I’ve got all of my laser cutter stuff ala leo’s article.

    As I’ve been using my mpcnc over the last few weeks, I have noticed that my table is not quite parallel to the cutting plane of my Dewalt.

    While I’m not sure of the angular variance, I know that I’m off by about 2mm from side to side. for cnc routing, I just accept that I’m cutting into my spoiler board to compensate..and I really don’t care about that.

    My question is:

    Will this cause a major issue when I put the laser cutter on the z axis? I know that the laser needs to be focused.. will 2mm throw that out of wack?

    Probably. How much, I’m not sure though.

    Short answer: No.

    Longer Answer: No, it will not.

    Assuming that you have a decent powered laser, that will be focused at 30-60mm, you should have a usable range of about 15mm (7.5 up and down from the point of focus)

    If you are doing image burning, the picture will get a little lighter/darker (depending on your focus point) towards one end of the table; but 2mm shouldn’t be noticeable.

    On the other hand, you could always loosen the flex foot on that side, lift the conduit 2mm, and re-tighten it… personally, I used a 1/2″ 6″ ratchet extension, with a socket in it, to even mine up.

    How could you fix this? Trim the legs?

    you could throw a larger router bit on the router and trim up the spoiler board so that it is perfect with respect to the router plane. then mount the laser..
