General Mach Discussion / Re: Random positioning motion on each operation start.
« on: March 16, 2018, 06:46:23 AM »
It is doing other strange things. Example, often if I pause an operation via the Space bar, normally it should resume when I hit Start/Resume. But more recently, it will often offset itself in Y by some amount (typically 0.3" or more), and/or attempt to rotate A where there is no A code in effect. I assume both have something to do with the machine zero being called instead of G54 (where right now, A defaults to 45deg, and this behavior is seen with the rotary table at 0 or 90deg etc). But there is no G28 called, so perhaps it is native to the system, or maybe it is buried in the config screen as a call on program start. But, seems to me 'resume' should not trigger program start calls regardless of where they are.
Ill see if there is a G28 in the startup command in the Config screen, but as to how these offsets are being introduced to the machine (vs just a move to machine zero before a WCS positioning call) I have no idea.
