So I created a file in Meshcam, and added a roughing pass with a #102 end mill…and then a finishing pass with a #101 ball nose. The rough pass went great. Carbide motion then paused and asked to switch to the #101 ball nose for finishing. I installed the tool and then clicked continue (resume cutting). I noticed right away that it started to cut about .06" off center. I paused and quite the job.
So my question is…do I need to re-zero the machine after a tool change?
Here is a picture of where I caught the error. The hole that was already drilled through on the first pass is the deeper one circled in red. The error is the smaller more shallow beginning of a new hole (that is not supposed to be there…it’s the same hole)…to the upper left.
