3.1 States
Work coordinates:
Represents current X, Y & Z local coordinates of the CNC.
Machine coordinates:
Represents current X, Y & Z absolute machine coordinates.
One of following CNC status:
◎
Idle - waiting for a G-code command Running - running a G-code command
◎
Home - homing cycle is executing
◎
Check - G-code command check mode is turned on
◎
Hold - paused by a "!" command, need to be restarted by a "~" command
◎
Alarm - CNC doesn't know where it is and blocks all G-code commands
3.2 Control
Home button
Starts the homing cycle procedure with "$H" command
Z-probe
Starts the zero Z-axis search procedure using the command specified in the
settings ("Z-probe commands" box). Example command: G91G21; G38.2Z-
30F100; G0Z1; G38.2Z-1F10
Zero X/Y
Zeroes the "X" and "Y" coordinates in the local coordinate system. Also retains an local system offset ("G92") for later use.
Restore X/Y/Z
Restores local system coordinates with "G92" command.
Safe Z
Moves tool by "Z"-axis to safe position. Position coordinate can be specified in the "Safe Z" setting. Position must be
specified in machine coordinates.
Reset
Resets CNC with "CTRL+X" command
Unlock
