    Re: ESS MB3 Analog to VFD LED on but no voltage

    In my other conversions, the ESS and MB3 boards are set up before connecting the VFD to confirm the AG/AO circuit is configured correctly in Mach. Once I get the correct voltages I connect the VFD...

    MB3 Breakout Board for ESS Smoothstepper

    I am at a client's shop in Florida and we have a dead MB3 board. We thought it was only the Smoothstepper, but it turns out to be the MB3 as well. Where can we get the MB3 board by Monday or Tuesday?...

    Re: Using BT40 Without Drive Lugs

    The spindle orientation not working is because I'm using a VFD and need to add a position indicator. I already have a profile set up in the VFD to run reversed at 30 rpm for tool height and diameter...

    Re: Mach3, ESS, MB3 and VFD

    Well, I finally got the AO to change voltages, but now the voltages are reversed. With an S10,000 I get a voltage of 1.23 and with an S10 I get a voltage of 9.25. Crazy. There has to be something...
