Masso

For Masso controllers.

What the file looks like

The file starts with comments naming the project, the machine and the tools, then:

G21 G90 G17 G94 G54

Millimetres are G21; a profile that outputs inches writes G20 instead. The spindle starts with M3 S{rpm} followed by a dwell (G4 P seconds) for the spin-up time in your profile, unless spindle control is set to none. Cutting moves are straight lines only — G0 for rapids and G1 for cuts, never arcs — and every line is 80 characters or fewer.

The file ends with:

G0 Z{safe}
M5
M30

Tool changes

• One file per tool works: run the files in order and change the tool between them.
• M6 and pause writes T{n} M6 then M0.
• M6 with G43 writes T{n} M6 and G43 H{h}, where h is the tool's length offset number, from the Masso tool table.

Before the first run

The file extension is set in the machine profile; change it there if your setup expects another.

Set X and Y zero at the front-left corner of the piece and Z zero on the top of the stock, and run the first file with the tool well above the work and a hand on the feed hold.
