I just ordered one like this off ebay USA for under $15 including shipping.
http://www.ebay.co.uk/itm/190893944941 £15.99 + £3.50 shipping from Guildford I like the design of it because it has four terminals for each motor drive, making wiring simpler than having to connect several wires to a single point like you do with BOBs that only have separate terminals for half the control lines. This BOB has support for 5 axes, a relay control for spindle on/off or other device, USB and wire terminals for power, a control pendant input and three connectors for 3, 4 or 5 axis digital readout. Here's a manual for it. http://www.marcmart.com/ebay/o/OT069/HY-JK02-M+5-axis+interface+board+manual.pdf Simpler wiring is why I bought it. Might get a control pendant sometime for easy jogging of the mill. This is the cheap cheap one that came with the motors and drives I bought. http://www.nbglin.com/cnc25.htm Supposedly supports six axes, have seen it setup with all the + control lines tied to the +5V input OR all the - control lines tied to GND at the bottom right in that picture. Seems like a good way to get everything fried if there's a spike on the +5V or GND where half the wires are all connected. -----Original Message----- From: aaron moore Sent: Wednesday, September 18, 2013 9:06 AM To: EMC userslist Subject: [Emc-users] Breakout board HI Can anyone suggest a good cheap breakout board, available in UK to run with Linuxcnc (of course) that makes it easy for an idiot to wire home and E stop switches.
