I just ruined another expensive piece of brass!!!
I've got an Accu Path II (Birmingham) with Centroid M400 and I have a lot of problems when I import .dxf files and use cutter comp.
First of all, about 80% of the time the software ignores cutter comp for the first move. After that it seems okay. I say 80% because it's not consistent.
Second, often either the beginning or end of a contour will have a "curl" which if it heads in the wrong direction I either ruin a part or snap an end mill....or both! What's frustrating is that I've loaded some complicated profiles and the program works beautifully and on some very simple ones it just seems confused.
This afternoon after playing with various moves to correct these anomolies (on a very simple profile!) I finally got it to graph okay. I analyzed it in both 2D and 3D and it was clean. Posted the program and ran it. Looked good. Changed the end mill diameter in the program to correct for an undersized end mill and didn't double check by graphing. And why would I? You got it....crash! Just changing the end mill diameter and it added a curl at the end of the final move. Don't know if it's me or Centroid but it sure doesn't make sense....plus I'm wasting time and material!! I'll be happy to send .dxf, .icn and .cnc files to anyone out there that wants to take a look. And if you can solve the problem I'll buy you lunch next time you're in Denver!!!
