Overview
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.

Start the job!
- 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.
