I would appreciate if somebody could give me some clue as to the
translation of Gerber photoplotter formats. So far, I have deduced the
obvious:
XiimmmYiimmmDnn move to position (ii.mmm,ii.mmm) and use aperture
nn (D01: open shutter, D02: close shutter, D03:
flash)
M02 concludes file
D10-D26,D70-D73 circular or rectangular shapes
* terminate record
G01 ?
G90 ?
G54 ?
Thanks.

G01 Linear Interpolation (Draw straight lines) This command is needed to switch back to line drawing mode after another G command. Some programs output a G01 before every move command. This is not needed, but it does not hurt. Note: some Gerber plotters support circular, parabolic, or cubic interpolation, G02, G06, and G07. They are not very common though. G54 Used before the aperture select commands D10-D26,D70-D73. Note: On some plotter controlers it is not neccesary to include a G54 before an aperture command. Be careful, because many Gerber commands do not work on all gerber plotter controlers. G90 I have not seen this one. Call Gerber and ask! (203) 644 1551 No Gaurantee on correctness of this info.
