as a hobby project (third one, i had only one before i bought this machine) i will do video progress of debugging it. and random tests.
i can foresee that at the end of this road i will have to buy G540. so i order it already with cables.
i will also put detailed price list of parts what you need to make it work as it should work out of the box.
ebay price vs real price.
thanks for the help.
