Need Help!- program exit sub routine

[MMTechi]

I post my programs to multiple size mills. I would like to use a common sub routine call that "moves to a operator select location at the machine" .

What I currently do is move to a suitable location for part change or clearance and capture it in my offsets page under G110. The common sub routine call at the end of the programs will use that as it part change location without the operator having to edit the program or manually inputting some locational values . This works pretty well unless I do a program mid start. It doesn't reread the part/program WPC at the top of the program, so it proceeds milling at some odd location based around G110. Is there an easy way to send tool to a temporary random location and still have it retain the main program work coordinate, I don't only use G54 when posting programs.

Can anyone tell me a better method of doing this? I have a Haas mill by the way.

Thanks in advance.

Too bad Haas didn't see fit to include Fanuc-style G30 (second, third and fouth reference position) function. Do you have Macros enabled?

Have you tried mid-starting with the Program Restart (setting #36) turned on? It will pick up the WCS.

I see in the Haas manual a G53 is a non-modal coordinate selection though I don't see a way to capture a random location and designate it as the place to got to for part clearance. I do not have macros enabled. Yes I know about setting #36 but i am trying to figure a way to not have it on. I don't quite remember something about it that slowed things down.

I believe Program Restart only slows down the search for the sequence number.

I may be nuts, but I thought I had read in an early Haas manual that you could use variables in place of numbers even if you didn't have Macros enabled. Can you enter a number into #501 in the Macro Variables screen? If so, can you MDI in a command like G00 X-#501?

Don't everybody yell at me at once...
