Thanks again andy. I'll give it a shot tomorrow.

Ok it looks like I put it there myself but I see no reason why it cannot be placed in the distro. How do I go about voting to get it in the sim directory officially?

Hi andy,

It looks like there's a bug in all the .ngc files where variable #2 is used in the "G96 D1500 S#2 ; Constant Surface Speed" lines before it's set. The fix I tried was to move the setting of the #1 thru #8 vars to the beginning of the subroutines. That seems to work.

One change I made was to move them all to after the "setup" codes. This was to prevent tool crashes when the positions are read in before the tool offset was applied.

It looks like I need to have a more careful think about this.

I also may decide to send the numbers from the GUI to the subroutines as parameters, so that the NGC code does not have to use the "experimental" ability to read HAL pins directly.

Since only the variables 1 thru 8 have been moved above the setup code then the position code shouldn't be affected. It's not much different than passing things in as parameters.

For me, the zip file comes up with an empty "lathemacro.hal" file which is the POSTGUI_HALFILE according to the .ini file, and from what I know that file should contain the _hal[gladevcp.turn.z-f] ... definitions? linuxcnc complains.
