[Emc-users] Connecting Mesa 25 pin daughtercards to 50 pin FPGA card??

HI Is this possible? For example, can I connect a 7i77 + 7i74 to a 7i80HD using a special cable? I see there is a converter board on Mesa's website, but I only realised now that I messed u when ordering, and also the 7i80DB's were out of stock. For this case, can I just refer to the pinout config

There is a good chance there was a wiring error in you original setup. The fact the E-stop did not work tells me there was a design error. E-Stop should never fail, or rather if it does fail, the machine stops. If the inputs on the drivers are blown, that says the same thing. Smaething was wron

Hi Guys, I was machining a part on my X2 Minimill. Suddenly it left the programmed track (spoiled the part) and didn’t respond to Estop. I powered the system off manually raised the Z axis and tried turning it on so I could home it, smoke started coming from the controller. So I powered everyth
