Tool to convert excellon files to 3D printer compatible g-code
Features:
-
creates Repetier compatible g-code from Excellon format
-
supports metric or imperial units for both input and output
-
rich options enable fine control of drilling process
Usage: exc2gcode.py [options] <filename> Options: -h, --help show this help message and exit -f OUTPUT_FILE, --file=OUTPUT_FILE Name of output file; if not specified stdout is used -u UNIT, --unit=UNIT Output unit (mm or in); if not specified the unit used in input file is preserved -x MAXSIZE, --maxsize=MAXSIZE Maximum drill diameter (mm or in) --header=GHEADER Program header --footer=GFOOTER Program footer --spindle-on=SPINDLE_ON Spindle ON Command --spindle-off=SPINDLE_OFF Spindle OFF Command --init-cmd=INIT_CMD Additional initializatiom --tool-cmd=TOOL_CMD Tool Change Command --msg-cmd=MSG_CMD Display Message Command --drill-height=DRILL_HEIGHT Drill Height (mm or in) --safe-height=SAFE_HEIGHT Safe Height (mm or in) --tool-change-height=TOOL_HEIGHT Tool Change Height (mm or in) --drill-speed=DRILL_SPEED Drill speed (mm/min) --retract-speed=RETRACT_SPEED Retract speed (mm/min) --move-speed=MOVE_SPEED Move speed (mm/min)
If Program Header of Program Footer are left empty reasonable and safe defaults are used.
Multiline commands are supported. Vertical bar (|) can be used as command separator` it will be replaced by newline in output file.
Predefined valuse can be stored in configuration files:
- file named
exc2gcode
in current directory - file named
.exc2gcode
in user's home directory (~/.exc2gcode
or%USERPROFILE%\.exc2gcode
, depends on operating system)
First the file in user's home directory is processed, then file in current directory is processed and finally command line arguments are applied. Configuration file format is straightforward - name of long command line option separated from value by colon, one option per line:
header:G92 X0 Y0 Z0|G90
tool-change-height:40
drill-speed:30
tool-cmd:M226 P11 S0
