Has anyone encountered the same problem and know how to solve it?
I have a mill with a 4th axis. Normally i do not use this A-axis so normally "A" does not appear in my programs.
However, when I'm running a program and press the feed hold button, the A axis starts rotating as soon as i press cycle start.
I did a small test in which the i made a program flattening program with only a G01 command and the X and Y coord.
As soon as i pressed feed hold the axis stop moving as they should, but after cycle start the A-axis revolves 180°.
After every feed hold it rotates 180° further. The speed of the programmed X and Y movement is at that moment reduced to match the speed of the A-axis,
so the X,Y move that was being performed when feed hold was pressed are finished at the same moment as the A-axis completes this 180° move.
After that the X,Y moves continue on normal speed again and the A-axis stops as if nothing happened, until i press feedhold again.
It does not happen after stop start jog or what so ever, only after a feed hold.
Problem is that i now want to start using this 4th axis and that i sometimes need to place a workpeace next to the 4th axis even when i don't use it.
This means i can not use the feed hold button or the part will become scrap metal or the axis will hit the workpeace.
If anyone has an idea what causes this problem....
