What did you try (include command-line arguments):
pcb2gcode --front pinpad-F_Cu.gbr

What happenned:
The gcode produced probes 70 points; #500 to #569, but then uses eg #578 during milling.
This appears to be because workareaLenX is calculated, but then the offset is added before milling (at least setting offset=0.0 removes the problem)
or

130c130,131
<     workareaLenX = ( workarea.max_corner().x() - workarea.min_corner().x() ) * cfactor + 
---
> //IAN
>     workareaLenX = 1.0 + ( workarea.max_corner().x() - workarea.min_corner().x() ) * cfactor + 
132c133
<     workareaLenY = ( workarea.max_corner().y() - workarea.min_corner().y() ) * cfactor +
---
>     workareaLenY = 1.0 + ( workarea.max_corner().y() - workarea.min_corner().y() ) * cfactor +

What did you expect to happen:
Variables/Registers to be set before use.
