Title: Mach3 M98 ignored
Post by: jeff114 on February 15, 2023, 07:08:13 AM

Hello,

I have a problem with M98 subroutine in Mach3.

If I run this gcode file:

Code: [Select]

G90

F2000
G1 Z -1
G1 X0 Y0

G91
M98 P1000 L4
M30

O1000
G1 Y200
G1 X200
G1 Y-200
G1 X-200
M99

%

the O1000 is never executed. When running in step by step mode, when the M98 line is focused, next step is M30 and not O1000.

If I wrote a second gcode file (1000.tap) and put it in the subroutine folder like this:

Code: [Select]

G1 Y200
G1 X200
G1 Y-200
G1 X-200
M99

%

and call it inside the main gcode file:

Code: [Select]

G90

F2000
G1 Z -1
G1 X0 Y0

G91
M98 (1000.tap) L4
M30

It works.
I try with .066 .062 and .043 version and it doesn't change anything.
Do you know where does come this problem? I haven't found answer on internet.

 

Thank you

jeff

Thank you JohnHaine,
I already read this post and it doesn't work with subroutine program within the current part program file (separated subroutine in another gcode file works).

Here is some code (actually for knurling with a rotary axis) which I know works.

G00 X1 Y0 Z67.595
G91
G00 A5
F100
G01 Z-1.397
M98 p2000 L37
G00 X1 Y0 Z67.595
G90
o2000
G91
G01 X10.783 A97.297
G01 X-10.783 A97.297
M99

The main difference I can see is that the "o" in o2000 is lower case.

Try it like this :-

%
G00 X1 Y0 Z67.595
G91
G00 A5
F100
G01 Z-1.397
M98 p2000 L37
G00 X1 Y0 Z67.595
G90
M30

o2000
G91
G01 X10.783 A97.297
G01 X-10.783 A97.297
M99
%

Thank you JohnHaine and Graham,
I try your gcodes with lower cases P and O but it doesn't change anything. I try with a fresh install of Mach3 .062 without any personal setup on a virtual machine and it dosen't work.
Is there a way to put Mach3 in debug mode to get log?

Whenever I use M98 and M99 I have always added an M30 (and % on a new line) at the end of the program after the M99 in addition to  the one after the M98

Thank you all !
