Is there any more info on this mod? I would like to do it to my GnR machine at some stage. Some pics of where to put the board would be appreciated or a link to any info would be just as good. Thanks.
I don't know of any link or pics but I would mount the driver board as close as possible to connector 3 (I think it is - near the top right of the MPU) and make the wires carrying the data as short as possible.
Then extend the magnet wires using heavy cable to run up to the relocated driver board.
