A CNC controller base on LPC1343 Cortex-M3 Chip

Installation

1. LPC1343 Side

   This Require the LPCXpresso to Compile and program it onto the chip, project file is included in the LPC1343 Code folder.

2. PC Side

   PC side Code is written in Python 3, should be able to run on any platform(Windows, Linux, MAC OSX).

   Dependience: - Python 3 - pyserial - numpy

   You should be able to install pyserial and numpy through pip install.

Usage

The following procdure demonstrate how to use a svg file to control the machine.

4. Set the settings according to this

   • Left Upper Side, set the px per mm for Illastrator
   • Right Bottom Side, Click all in mm
   • Left Bottom Side, Set Tool Diameter as the Tool on the machine.
   • Left Bottom Side, Set Rapid as 20mm, Cut as 1mm
   • Right Upper Side, Make sure Z Orgin is Top, and set Clearence as 0.

5. Click On the Create Operation Button.

6. Below that, choose Engrave

7. Click Generate and chose the Simulate GCode Tab the preview the result.

8. adjust the Pass Depth Option the create a multi-pass Tool Path.

9. If you are satisfie with the result, Clicke Save GCode to Download the Generated GCode

10. Now you will need to open a console window at the PC Side Code Directory, issue the following Command

    python ./main.py -f path/to/gcode/file

    (Make Sure your python is link to the right version(python 3), you might want to use python3 instead)

11. Choose the right Serial Port and press Enter

12. Things should Work
