I carved that last night, and in Vcarve it was on a 24"x24" sheet. I did multiple tool paths, with the hollow portions being “inside” the line profile cuts, and the outline being a outside the line profile cut. The sheet of MDO I used was 24.0625" x 24.0625".
1 locke in the back of the main, and the 3 tips on top all had the CNC moving beyond the cut area, I’d say somewhere between a 1/16th and 1/4.
Now I can save this with some clever sanding, but I am not sure why I exceeded the cut area. I have to cut out some nested parts next, that if they are short, I for sure won’t be saving them lol.
Edit: I should add, it was centered on the 24x24 project in Vcarve, and the line was close to the edge. I was making it as close as I could.
Did you use the correct sized bit for what you selected in CAM? For example, if you selected a 1/4" end mill in CAM but ran it on the CNC with a 1/8" end mill, then the outer profile would be offset outward by 1/16".
Yea, I made the gcode with a .125 down cut end mill, with a 1" LOC from Bits & Bits, and that was the bit I used…
Would setting it to cut “outside the line” cause it to be slightly larger? Like I know it would be bigger then I side the line. But would it cause it to be larger then the cut area? It’s so weird.
I’m thinking I’m out of square or something. It’s weird, cause I squared up originally. I just attempted to put a perfect square on my scrap board. Ran the bit around it, and it kept going off. When I finally got it to stay perfect on the edge of the Y axis square, running it along X axis, I was off by like 3/16ths or less? I unscrewed the X rail, and tried to aline it, didn’t seem to work. But then all of a sudden, it seems square again. I can go around the entire square staying on edge.
Not sure if I fixed it by adjusting the x axis, or if my bench is tweaking just ever so slightly… The bed is a torsion box, so it really shouldn’t be tweaking at all.
I’m about halfway through my nest cut and everything seems perfectly where it’s supposed to be. So idk.
