Well I had a program running that pocketed 3 small holes, then did a contour around the part. After doing the holes, it was moving to the contour position when it stalled.
Then I clicked emergency stop.. Homed it. Then I scrolled through the Gcode to the point where the contour job was, click run from here. And on the same move, from the posistion of the last hole to the contour position it stalled again.


Then I redid HSMExpress, to just do the contour job and not the holes (which were already done) and all was well.


However, I didn't try to repeat it this morning.. stupidly I changed something that I had read fixed this issue on somebody else's machine.. (putting the PC driver to "standard PC" rather than ACPI) and now it's not stalling there during that job (in air.. moving)


I should have tested it this morning without changing anything to make sure it was repeatable every time.


I guess I'll continue to monitor it.






There was another moment that it stalled previous to that halfway through a pocket program on the Y axis this time. Again whilst moving in air to its next hole.
