    Good evening Robert,
    My name is Pedro and I have recently discovered your projects that I am fascinated by. I have gotten to work with your Arduino ASCOM Focuser Pro2 DIY project in version 330 with the myFP2F_L298N_330 firmware with a Nema17 motor.
    I have it loaded on the board and everything is mounted correctly, I have downloaded the ASCOM Driver and I want to use it with N.I.N.A. When I plug it in, both N.I.N.A. like ASCOM, they recognize the focuser.
    My problem is that the motor does not move and, depending on how I drive it, the following happens to me:
    1) ASCOM:
    The engine does not move and overheats. When touching it when it is sending a movement, I can notice vibrations and the shaft is completely rigid and with the force of the hand it cannot move.
    2) N.I.N.A:
    The motor does not move, it does not heat up. When I touch it when it is sending a movement I can notice vibrations and the axis feels free and with the force of the hand it can move.
    I don't know what could be happening. To rule out a breakdown in the motor or errors in the connections, I have loaded a simple command into the Arduino to move the motor in one direction and another and thus if the command is executed correctly and the motor rotates in one direction and the other.
    I don't know if something similar has happened to you or, based on what I've written to you, you know what it could be...
    Without further ado, I say goodbye, waiting.
    Thank you very much for your time and your great initiative.
    Receives a warm greeting.

    Hi
    The issue is probably the Library TimerOne.
    Some versions of this are faulty.
    Delete the existing TimerOne library as shown below

    If Arduino is running, click File, Preferences and find where the Sketchbook Location is. Mine says

    d:\Documents\Arduino
    

    Navigate to where yout location is. You will see that there is a Libraries sub-folder
    Open the Libraries folder and Delete the TimeOne folder.

    Next, Close the Arduino IDE program
    Then
    Back into the myFP2 firmware folder, In the folder Libraries_To_Install you will find TimerOne folder and library.
    Copy the TimerOne folder.
    Navigate back to the previous Arduino\libraries folder paste the TimerOne folder.
    next, start the Arduino Ide and load the myfp2 firmware, then reprogram the controller

    Regards
    Robert

      Good evening Robert,

      Thank you very much for your prompt response!! I have tried to put that
      library back in that directory and the problem persists.

      Checking your project page I saw a response from you to another person who
      feared the same problem.

      In that answer he recommended changing the wires that connect the coil to
      the L298N from A1 to B1 and vice versa and that has turned out to be the
      problem.

      Apparently the colors of the engine streets that I have used do not
      correspond to the same order of the scheme. That "silly" detail has made me
      have to go to the point of "bothering" him for practically nothing...

      That order has been changed and it is now spinning correctly. I just need
      to finish the assembly and do the first tests with NINA and then put it to
      work with my Newton 150/750.

      I want you to know that I will send the first astrophotograph you take
      with your focuser project and dedicate it to you.

      Thank you very much again for your enormous generosity in giving us your
      time.
