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?June 29, 2016 at 3:06 pm #14129
Probably. How much, I’m not sure though.July 5, 2016 at 10:08 pm #14466
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.July 6, 2016 at 5:04 am #14476
How could you fix this? Trim the legs?July 6, 2016 at 5:41 am #14477
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..
