Mach won't load this parametric g-code

[OCNC]

Mach3 won't load this parametric code. Is it a syntax error or just not within Mach's capabilities? It's hanging on line 4 not liking the word 'If'.

Thanks.

Chris

As answered on the Mach forum, Mach3 doesn't support conditional stuff in the g-code.

You can work around this by creating VB macros and calling them via M codes.

Can you point me to any info on writing VB macros for Mach? My understanding of the Mach macro stuff on the Mach website is that it's for controlling the Mach screen interface which isn't what I'm trying to do...but maybe I'm confused about this.

Thanks.

You can send g-code commands via VB.

A good source of info is the wizards. View the VB code in the buttons for examples. Use operator>edit button script and click the flashing buttons to see the vb code.
