Feed rate control??

I use vcarve v7 and I know you can change the feed rate or IPM, but is there any wany to change this increase or decrease while the design is cutting?

You can use the feed rate slider in the AXIS gui. Which should appear on the left side of your screen if it has been set in your ini file.

Section 1.3.7

The amount of override is set in your ini file with

2.2. [DISPLAY] Section

Different user interface programs use different options, and not every option is supported by every user interface. The main two interfaces for LinuxCNC are AXIS and Touchy. Axis is an interface for use with normal computer and monitor, Touchy is for use with touch screens. Descriptions of the interfaces are in the Interfaces section of the User Manual.

DISPLAY = axis - The name of the user interface to use. Valid options may include: axis, touchy, keystick, mini, tklinuxcnc, xemc,

POSITION_OFFSET = RELATIVE - The coordinate system (RELATIVE or MACHINE) to show when the user interface starts. The RELATIVE coordinate system reflects the G92 and G5x coordinate offsets currently in effect.

POSITION_FEEDBACK = ACTUAL - The coordinate value (COMMANDED or ACTUAL) to show when the user interface starts. The COMMANDED position is the ideal position requested by LinuxCNC. The ACTUAL position is the feedback position of the motors.

MAX_FEED_OVERRIDE = 1.2 - The maximum feed override the user may select. 1.2 means 120% of the programmed feed rate.

MIN_SPINDLE_OVERRIDE = 0.5 - The minimum spindle override the user may select. 0.5 means 50% of the programmed spindle speed. (This is useful as it’s dangerous to run a program with a too low spindle speed).

MAX_SPINDLE_OVERRIDE = 1.0 - The maximum spindle override the user may select. 1.0 means 100% of the programmed spindle speed.

PROGRAM_PREFIX = ~/linuxcnc/nc_files - The default location for g-code files and the location for user-defined M-codes. This location is searched for the file name before the subroutine path and user M path if specified in the [RS274NGC] section.

INTRO_GRAPHIC = emc2.gif - The image shown on the splash screen.

INTRO_TIME = 5 - The maximum time to show the splash screen, in seconds.

CYCLE_TIME = 0.05 - Cycle time in seconds that display will sleep between polls.
