    Hello.

    I upgraded to firmware 2.05 about 2 weeks ago or so. After doing so, nothing happens when I try to move a motor. At first there were some errors about phases, but now nothing at all. The wiring did not change at all, and I'm sure I have the phases correct. After sending a move command, nothing errors out, and the system message at the top will say "Busy" for a moment, then it will report the axis position as moved that amount. I.E. I press x+10 after boot up, and x position reads 10, but no move. If I try to manually turn the motor after making the move, it spins freely.

    Now, the odd part: All heaters, fans, and thermistors are still functioning 100% correctly. Even the ir sensor and endstop leds will still go red and report that it is triggered. I have checked all fuses, however my Duet Wifi 2 is an older model when they were soldered on. 5v and 3.3v rails all show as working properly under my multi-meter.

    So I went back to the 2.02RC6 that was on it originally before all this. I unplugged all drives, plugged in only 1 to drive 2 which is set at X in my firmware, powered the duet back on, and tried to run it. Still nada.

    I tried a breakout and a bare ramps board from the expansion header and the same, so decided to scope it. No signals are going out for en, step or dir from any pin on the board.

    Since I have tried upgrading on to 3.0. No go still. I know it's way out of warranty as I bought it in 2017, however this board only had about 50 - 60 hours of total print time (Was on my Mono Maker Select v2). Anything else I can try, or test to see if it is a single driver being bad? I have used the multi-meter and verified no voltage is coming from any pin when I tell a motor to move using the test pads on the board.

    I do have access to a 4 channel Rigol scope at home, and a nice Keysight one at work if I need to scope anything.

      Are there any error or warning messages when you try to move the axes? If the printer hasn't been homed then only G1 H1 and G1 H2 moves are allowed. So send G91 to select relative movement, then test the motors individually using G1 H2 X10, G1 H2 Y10 and so on.

      The most common cause of motors not moving is configuration errors, or config.g not being read. Send the following commands without parameters and check that the values returned are as expected:

      M584
      M906
      M913

      Also please post your config.g file.
