  • Centre line of spindle to column 130mm (5.1")
  • Table to column 5 to 130mm (0.2" x 5.1")
  • Tee slots 2 x 10mm

Updates

  • 13-Oct-2015 : System is now up and running using BCNC on Ubuntu
  • 15-May-2015 : Dean, Phil et all doing conversion to Mach3 capable machine which will involve minimal retrofiting of mill and use of a PC
  • 24-SEP-2014 : Mill works with V5 of the boxford software, need to enter administration mode in the graphical screen by pressing F10
  • 12-JUL-2014 : Connector is DB25 and almost certainly serial. It appears there is an internal g-code interpreter.
  • 10-JUL-2014 : Mill arrived, mechanics and electrics work, has a 25W serial port out the back, need to research how to interface.

ToDo

  • Chip removal / coolant (compressed air or liquid pump)
  • Finalise training

More info

Boxford are said to be unhelpful regarding support and will only talk to educational users. However, they do publish spares lists and software updates.

Needed

  • Coolant / chip removal system - those chips build up fast! Either a suds pump or (quiet?) compressor/non fogging mist will be needed as the interlock prevents manual removal of chips during a program.
  • ER type collect can be had from Gloster Tooling a price has not been obtained yet the, model is EC EM16 035 on page 8 @ http://www.glostertooling.co.uk/backup/download/Engineers%20tool%20catalogue.pdf

Not needed

  • People who take it apart and leave it in pieces
  • Experimenting carelessly. Consider it in the same light as the laser cutter, the robot arm etc. : if you want to work on it, join the official maintainers group and cooperate.

Troubleshooting

  • The cutter appears to spin off-centre
    • When slotting in the collet make sure to put it the right way in as it's got a notch which will only go in fully when aligned

Training

The system is currently in an "beta" state. If you would like to get trained to do a specific job you have in mind, on the understanding that you may find issues along the way (which helps us too!) you can email the Robotics mailing list to arrange a time for training. You will find this easiest if you take a look at one of the recommended packages above (or your own choice of package, we will try to accomodate).
