Hi Folks,
I'm new to this forum and (very) new to CNC. I've spent approx 2 months researching and trying to find all the info I can on the process for CNC.. I've got a MyDIYCNC for starters and am using CamBam / Mach3 to product the end product. I have an issue with my first milling exercise. Got an item in CamBam and it has all the measurements I expect. However, when I cut it in the mill, the entire unit is being cut at a smaller scale. However, I don't recall setting anything that would change the scaling of the milled product. Can someone direct me as to what I should look for to determine why this is happening. I figure the output product is approx 60% the size of what it should be. I'll also add that I created another part (a box)in CamBam with a specific dimension 11mm x 13mm to profile and it came out to about 6.5mm x 7.5mm. Any ideas?
