Thanks John, thanks for the warning about the fakes, could be i guess, just seems a bit too uncanny that it would blow so soon after the original non fake on that was in it as that was the original chip.

Im seriously considering building a new box from the ground up, if theres one thing i dont like its worrying whether the machines gonna blow up during a cut, especially as i cut expensive material usually so it can cost me big if it craps out.

Ive alwasy been a bit dubious about this control box to be honest
