So- I'm teaching myself CNC... and have run into a problem.
In Aspire, I designed a simple 2" X 2" square, generated a pocket toolpath, and sent it to Mach3.
The results, seen in pictures 1&2, show that the square is 1.986 in both X and Y.
Next, to verify that my motor tuning is correct, from Mach3 I cut a simple straight line 2" long with a .25 end mill- pic 3. I also am posting a screenshot (picture 4) of Mach3 showing this cut went 2.0018 inches... 2" plus .25 for the end mill= 2.25, and I cut 2.2505- close enough for me.... So, motor tuning is (almost) right on...
So, why is my pocket 1.986 instead of 2"? What am I missing?
I also have included the .txt file for the cut...
Any suggestions/direction would be GREATLY appreciated?
Thanks so much for your time...
