    The 36v psu is connected to the motor drive boards, the 24v one is connected to the BOB.

    Previously I only had the 36v psu connected to the motor drives AND the BOB.


    I have just tested it again with a different 24v PSU connected to the BOB, this one is a PLC supply so pretty good quality.

    It worked ok with the torch off, ran a cut program 10 times in succession and all worked ok.

    Connected up the plasma and did a quick test pierce and down it goes again, no movement on the motors.

    This now confuses me as it seems the BOB is OK still but i have serious issues elsewhere, trouble is i dont where or how to test them????

    Following a reboot, normal control is returned.

    The PC showed no signs of a crash, no lock-up or BSOD etc.

    Not sure which way to go now but clearly i have issues.

    Well the BOB is not fried so that is good news. When you say after a reboot and also say the PC shows no signs of a crash!! Does that mean that Mach3 locked up and could not be reset? It does sound like RF problems though I have never used a plasma before so can't help you there. Some pictures of you setup might help others glean some info.
