    Not very often Syntetos answers this forum anymore?

    I did find the schematics it appears, but it was the wrong version and said TinyG so I did not think I could use that.. But it was helpful..

    I will answer myself then:
    The LED is connected to the H bridge ie the same as the steppers. That is why the LED lights up when you turn the steppers by hand.
    Resoldering did not help, everything was soldered ok on the board.

    I replaced the 8811 with a 8818, and now it is up and running again.

    If you have an extra Arduino, you could use it to program the first one: http://arduino.cc/en/Tutorial/ArduinoISP

    I do not usually drive my ShapeOko entering commands. I create a job in Cut2D and then move the spindle with buttons in Universal GCode Sender: https://github.com/winder/Universal-G-Code-Sender

    I usually set the job to start in the middle of the material and move the bit so it touches the wood, plastic or whatever I am going to mill.

    Then I start to transmit the gcode fil.

    The file includes commands to rise Z to a safe level, moves to where the job starts and runs through the job, returning to 0,0,0 and rises to 20mm over the start.

    I can post a minijob if you need to look at the code.

    I have the same problem, but with the Z.
    A small job went OK, and suddenly no reaction when manually trying to move Z up and down. There was no loose connection or short circuit, and the stepper works when I rewire it to X or Y.

    The LED never lights up anymore for Z.

    Is the LED controlled by the DRV8811 or the Arduino? I did not find the schematic for v3 of the board that I have on the web.

    I will try to resolder the chip, but the last job I ran did not even make it hot to touch and I do have a fan to cool the board.

    Would it be possible to replace the 8811 with a 8818 as I do have a SMD heath tool?
