Bob,
Usually, I have both boards set with the VCC jumper set to the 24VT position. When I couldn’t get the ports to respond to my lap top I changed one jumper to USB to see if it would make a difference. It didn’t. Then I took the picture. I have tried flashing again and no change.
It doesn’t seem my firmware is having an effect on the SKR board and it is not loading. Are my SD cards set up correctly? Is the firmware from MPCNC loaded for 250000 baud?
Different subject: my machines were made 5 years ago and I wired them in series. I have more drivers but just split them between the three boards. I have been using the x, y, z, placement on the first, second, and third port on the drivers. But because I don’t get any stepper signal I haven’t noticed their positions were wrong.
If I have an older machine that is wired in series what is the exact firmware I should be loading? I would hate to think I wasted your time by selecting the wrong firmware bin. Does this firmware work with both the TFT screen and the Marlin program?
