Miscellaneous Setup Parameters
The Miscellaneous Setup Parameter Group ranges from MC_4300
through MC_4399.
The Miscellaneous Setup parameters enable you to configure various
CNC functions not addressed by other setup option menus. These
functions are detailed in the following subsections.
Linear and Rotary Axis Dry Run Feedrate
MC_4302: Linear axis dry run feedrate
MC_4306: Rotary axis dry run feedrate
When a program is run in Dry Run Mode, the machine’s linear axes (X, Y,
and optionally Z), and rotary axis move through the program without
cutting into the work. The CNC activates Coolant Off and the work may
or may not be placed on the table.
Dry Run Mode is activated by M-codes M105 and M106 and deactivated
by M107. Refer to
Table 2-6, Dry Run Mode M-Codes
Run related M-codes. Dry run feed rates are set in the Setup Utility.
They are often faster than conventional feed rates, but can be set at any
rate.
