This is an old revision of the document!


State of the Group

* Final paper word document is on my dropbox. If you're not a member of the shared folder, email me (Jordan). * We got the $2000 macro code for free! Hooray!

Current Method

* Extract the 5 “Additional Axis” from the 2nd serial port as 4800 baud data streams with an Arduino. * Arduino generates PWM signal for laser power supply based on data read from the CNC. * Hook up digital switches and analog sensors to Arduino input pins. (Eg, temp sensors, door switches)

Bill Of Materials

Part Name Price URL Remarks
Amphenol MS3106F20-29P $24.75 product page Needed only for testing. Not for final bill.
Amphenol MS3106F20-29S $31.16 product page Needed only for testing. Not for final bill.
Arduino Main Board $30.00 adafruit Lima had one of these in his office.
Can style power connector $3.00 adafruit I'm sure we have one
Molex extension cable $3.99 product page We already have one.
Microswitches ~$3 per switch I'm sure we have tons in the J-Lab
Our Final Cost
$55.91 $50
  • A $2000 option code is required to enable macros on the CNC machine. HAAS generously gave us this code for free. This is implementation specific, so should not be included in the bill of materials.

Plans for next meeting

  • Call HAAS and inquire about the Servo Control serial protocol. Also ask about the pins on the DB25 connector. There is no data in the manual about this connector or it's protocol.
  • If this fails, hook up all pins from the DB-25 connector to the oscilloscope. Read any and all pins that appear to be digital serial with Arduino. Try to reverse engineer the protocol.
