Editor Gcode parsing breaks editor

[amateurengineer]

Hello,

when I import a gcode made from a pcb design made in KiCad, then translated from gerber to gcode with pcb2gcode the Editor falls into weird behavior:

• The scaling of the object is correct
• If I move an object 10mm by mouse it will be moved by 2,54 * 100 in that direction.
• The Predefined move tools also fail in a similar manner (the to move direction overshoots by that value).
• Objects like bowl are too big by 2,54 * 100

In the gcode file header is the G20 statement

G94     ( Inches per minute feed rate. )
G20     ( Units == INCHES.             )
G90     ( Absolute coordinates.        )
S30000  ( RPM spindle speed.           )
M3      ( Spindle on clockwise.        )

when it is removed like

G94     ( Inches per minute feed rate. )
G90     ( Absolute coordinates.        )
S30000  ( RPM spindle speed.           )
M3      ( Spindle on clockwise.        )

• the editor is just fine but the objects scale is off by 100

I hope this wasn't reported already, thank you for your work.

Have you configured bcnc to inches in the config?

Hello, Units (inches) is unticked.

I have compiled pcb2gcode v1.2.3 from source to make it accept metric-output option which works around the problem.
