Post Processor Error Checks for Home Values

[clifftm]

Using Mastecam X5 mu1

 

Hope someone can show me what I am doing wrong...

We are using a modified mplmaster post for a lathe.

An error error check has been added that gets the x home and z home for each operation.

I can get the xh$ and zh$ value but the zh$ causes some undesired output into the G code file.

 

The code below gets the x home value for each operation with no problem.

 

xhome = vequ(xh$)

xhome = xhome * 2

xhome = -xhome

sxhome = no2str(xhome)

 

However when I try the following line to get the z value the undesired code appears.

 

zhome = vequ(zh$)

 

When I use # to make it a remark or get the xh$ value a second time the error goes away.
