Drilled Hole Locations

[Robs-shiz]

The problem that I am having could be related to a CAM issue (Soildworks CAM standard) but thought I would ask the question since I had a hole pattern related problem in the past. The previous issue was then the machine went to drill a pattern it would skip the first hole it was supposed to drill. With cncsnw help It turned out to be a parameter number that needed to be changed.

The current problem is when it goes to drill the pattern it appears to go to the correct locations in X but the Y position is incorrect by a significant amount. I just recently updated to the latest version of CNC12 and wonder it this could be another parameter that needs to be corrected. Attached is my report. Any help is appreciated.

Thank You

No, there is no parameter setting that introduces a Y axis offset to drill locations.

The first thing you should do is look at the X and Y coordinates in your G code program, and see whether they match up with your intended hole locations; and likewise whether they match up with the locations in your CAD drawing.

You can also pause motion while it is at a hole location, and see whether the X and Y on the DRO match the positions in the G codes.

Since you have a closed-loop control, the position shown on the DRO is based on the servo motor encoder feedback. That is where the servo motor really is, not just where the control hopes it is.

Do other features in the same program (other than the drilled holes) cut at the correct Y coordinates? Or is everything in the program cutting at the incorrect Y? If the latter, then it is likely operator error: you did not set your Y axis part zero at the location that the CAM software assumed it would be at.
