M98 unknown m code used

Hi guys.

I am trying to make a simple program with M98 subprogram call.
When i am trying to load it in "controller" i am getting error:
Unknown m code used: M98

Can linux cnc use M98 M99?

Here is sample of program

Thanks for help

(1001)


#1 = -37.5 (CENTRE OF THE GROOVE)
#2 = -3 (TOOL WIDTH)
#3 = 50.2 (X START POINT)
#4 = 40 (X END POINT)
#5 = 7.5 (WIDTH OF GROOVE /2)
#6 = 0.1 (FEED)

M98 (ala Fanuc) is new to Linuxcnc. I have never tried to use it except on a Fanuc control and I'm not sure exactly how it is implemented or if it is in the current 2.7 version or if you must use Master to use it. What version of Linuxcnc are you using? Also variable numbers lower than 30 are not passed to a subprogram (they are not in Fanuc code either. ) you will need to use bigger parameter numbers for passing values to your sub.

The normal Linuxcnc way to make a subprogram is using o-calls like this

. I have version 2.7.14
I was trying to use linux cnc like simulator to prove out simple macros.
Well there is better software online for it.

I have fanuc 21i 31i oi-td series at work and all of them will pass 1-30 variables to the subprogram
difference on our machines between 1-30 and 100-199 is that controler will delete data in 1-30 if the machine is powered and save date in 100-199.

Thanks.

I thought for sure our oi machines didn't pass those, maybe they only clear them on m2/m30 and I was wrong. I don't use custom macros more than I have to, and one of our Fanuc machines doesn't have the option and we run mostly cam generated code.

For writing and simulating Fanuc macro programs I use NCplot.
