I am new to this so hopefully the solution is an easy one.
I built my router and have it up and running just fine. I have had success tuning the motors and when I tell it to move a certain distance it does to within .001 inches, which is fine for what I use it for. The issue is that the parts I cut out look like they are right, but are off proportionally by a lot... sometime by more than an inch. I can repeat the part, and while all the parts are the same, they are all wrong by the same amount.
I am using AutoCAD, outputting a dxf to Lazy Cam, creating all of my tool paths and sending it to Mach 3 for cutting. My line of logic is that something is not translating right in one of these steps. I also think this is a software problem and not a machine problem because the parts created are all identical... meaning all sides are completely flush with one another. So repeatability is not a problem, I just need it to reproduce what I drew faithfully.
So if one of you more experienced (not necessarily older) CNC guys out there would be so kind as to point me in the right direction on correcting the error of my ways I would really appreciate it.
Thanks, Dave
