G-Codes (Preparatory Functions) - ZAPbp BP93p Operator's Manual


Each block (line) in the program must start with a G- or M-code. None of the data entered before a G-
or M-code will be interpreted.

Incorrect parameters for a given G-code will not be interpreted.

If a parameter appears twice in a given block (e.g. G00 X2.0 X3.00), it will have the value of the last
entry (in this case,

It is not possible to add comments to the file that contains a stored program.
