Cheap ebay BOB Build:

[JAZZCNC]

fact is my Control box has issues where I have gone through several BOB and still not been able to use my CNC machine. In my previous design the BOB outputs where being blown so this time round I have decided to start again with a control box design as the previous was a bit of a Frankenstein.

Don't you think it's about time you started asking the question WHY.!! . . . .If you have gone thru several boards already then I'd suggest your doing something wrong.? Just throwing a differant BOB at it won't stop you blowing them up if your wiring them wrong.

What exactly is happening or not happening. Give exact details of what you have and how your wiring it and lets see if we can find the problem.
While Cheap BOB's are pain in the arse you shoudln't be blowing them up so easily or often.

Erm ok, of course, but let me explain more, not all boards blew for the same reason, but the last two, one of the axis stopped working and then the last one while running the machine blew.

also the way I have built my machine is an very usual one. I started with this in 2010 and it was kind of struggle. I didn't always have time to dedicate to it and other lifes problems etc. but instead of selling it I want to see it working and complete the work my self and also so I cut projects i built it for.

I have seen the machine working and moving with limits and homing and then something blew inside the box. Currently I'm rewiring so it is easy to debug and will post maybe in a new thread??? my progress.

Much appreciated.
