Hello..
I write hole center probe subroutine and works nice if it's called from main program.

in test.ngc I have
o<hcenter> call
M02

and that's works without problem.

but if I type
o<hcenter> call
in MDI mode the only 1's move is ok and after that the move's are unpredictable for my opinion.

and there is hcenter.ngc
o<h Center> sub

F200			;set feedrate for probe

G30.1 			;Save current coordinate 
G38.3 Y285 		;Scan +Y limit
#100 = #5062		;Save +Y limit
G30 			;Back to start cordinate
G38.3 Y-4		;Scan -Y limit
G0Y[[#5062+#100]/2] 	;goto aprox Y center 

G30.1 			;Save current coordinate 
G38.3 X255 		;Scan +X limit
#101 = #5061		;Save +X limit
G30 			;Back to start cordinate
G38.3 X0		;Scan -X limit
G0X[[#5061+#101]/2] 	;goto exact X center 
#101= [#101-#5061] 	;calculate span X

G30.1 			;Save current coordinate 
G38.3 Y285 		;Scan +Y limit
#100 = #5062		;Save +Y limit
G30 			;Back to start cordinate

G0Y[[#5062+#100]/2] 	;goto exact Y center 
#100= [#100-#5062] 	;calculate span Y
#102=[#100-#101]   	;excentricy
#100=[[#100+#101]/2]	;XY diameter
(debug, Diameter+probe=#100, excentricy=#102)

o<h Center> endsub

Hello,

I believe that if you enter the code from the MDI window EMC will be in MDI mode and only expects one line of code.

Definitly more than one line is executed!
At least machine does move but in nonsense direction and result is printed out again with nonsense values.

For those who are following this thread the information above is a little thin. Depending on the version of EMC you are using o<filename> call from the MDI line may not be supported or work reliably. However it seems that this is currently being addressed. There is more about this on the EMC mailing list.
