Getting Started

1. Start with a DXF file.

CamBam can open other files, but I have only messed with dxf so far.

2. Open in CAM software, produce GCODE. Make sure you are set to metric.

add config settings
  • Profile
    • Inside/Outside - pick the side that you want the bit to cut around
    • Clearance Plane = ===== 15 ===== this is how high to raise the bit in mm when travelling
    • Depth Increment = ===== 1/2 the bit diameter ===== this is how deep the bit cuts, I fudge a bit for 1/8" bits and sometimes do 2mm it the wood is soft
    • Target Depth = ===== The thickness of the workpiece + 1mm ===== this is how deep to cut, it can be less, but should not be greater
    • Feedrate = ===== ignore this =====
    • Holding Tabs = ===== RECOMENDED.===== Set to auto, the generate toolpaths, then click and drag to position tabs as desired. I usually set ti to square, and make it at least 5mm high and 10 mm long
    • Corner Overcut = set this to introduce dog boning
    • Tool = set this to the diameter of the tool

3. Load GCODE onto a thumb drive, then plug it into the CNC's Controller.

4. Turn on the CNC, Navigate to the File menu.

  • Remove the old job, leaving the two default jobs alone.
  • Copy the new job from the thumb drive to the Controller.
  • Ensure that the bit is correct for the GCODE you CAMmed.
  • Set your origin.
  • Start the job!

What to do if something goes Wrong

  • Pause the Job
"Run/Pause/Delete" button pauses the job if you are cutting
  • Stop the Job
the yellow "Stop/Cancel" button stops the job and gives the option to save the position. Use this if you break a bit! Save the job and then return to origin.
    • Restarting a saved job
to resume a stopped job: press RUN button and the number of the job (eg. Run+1) then click ok.
