Hacking Interfacing the Boxford 190VMC
Long ago this CNC was controlled by a BBC Master from Acorn.
I just found a disk with the software used to control the Boxford 125 tcl lathe that happens to have a very similar electronic board as the 190VMC. To emulate the BBC master on a Windows7 sytem I have used "BeebEm 414"--->http://www.mkw.me.uk/beebem/ and the disk can be downloaded from here: https://groups.google.com/group/london-hack-space/attach/8f627b29677a61fb/Boxford200K.ssd?part=0.1&authuser=0&view=1
It could be a starting point for decoding the initial handshake to control the drivers. The documentation suggests that it uses standard gcode (ISO)---> http://tturkyilmaz.home.anadolu.edu.tr/dersler/telatturkyilmaz/programlar/cnc/millcamakz/millcam.pdf
Yesterday I was able to connect to the cnc via serial(b:9600 d:8 s:1 p:none) and get its model but could find any code that actually moves the motors.
