I have been thinking of the MM test board cut that Gerald mention in a backlash thread. The Idea is to have a file that we could all share and cut on our own MM’s to compare and fine tune our machines to be as good as they can. I wanted to share my thoughts on it.
I guess it would be best if it is G-code and not a .dfx file because of the difference in post processors. Theo I am not sure if that is possible (software not my strong suit) I would also guess we need one for us standard guys and one for you other people:rolleyes:. I can’t decide what the material should be, I think it should be ¾ MDF, but a full sheet! Kind of seems wasteful. Also what bit to use? What are the most common bits to be found around the world??
I would think the test cut sheet should include the following:
-Cutting an inlay out and installing it some were else on the sheet
-Cutting a large rectangle to test how square the gantry is
-Some sort of cut to check if the Z is plum??
- have the bit make a hole and after all cutting return to that hole (e.g. it did not lose steps)
-Cut a concave 3D and a convex 3D shape
-cut some V-carve letters in various sizes
- cut a square sign wave pattern to check Acceleration and CV settings
- Maybe a texture pattern??
-Is there a cut to check backlash??
-Is there a cut to test if the machine is blue??
I know a few of you offered to help put it together (I can’t, software thing:o) So I thought this thread may start the ball rolling.
(p.s. Gerald if I put this in the wrong spot, sorry could you place it where it belongs please)
