    Hi all!

    ;currently tested (little by little
    because I didn’t have much spare time right now…) and I have found at
    least 3 bugs in the current design of the ControlPCB.
    These bugs are easy to fix, but I’ll update the electronic design in order to have a bug-free PCB.

    The bugs I have seen so far are:

    1. Solder
      pads for the Power and Switch terminal blocks are in the incorrect
      side. Quick fix: Solder it through the hole or applying some solder
      paste in the solder pad before introducing the terminal block.
    2. The
      Tool control pin is currently connected to the Mega’s pin 40 which is
      not a PWM pin. Quick fix: separate the Tool wire from the ribbon cable
      and connect it to a free PWM pin (for example: pin 7).
    3. LEDs are
      too bright. I have to check the values of the resistors since the leds
      are so bright that them can hurt the eyes. Specially the USB one. Quick
      fix: Probably a higher value of the led resistors will solve this minor
      bug.

    Except for that bugs, the PCB works well.

    I will upload soon the fixes, the grbl version for this board aaaaaand a diagram of the PCB connections.

    Best regards!
