Ok. This is pretty strange. On my PRT4G I had a bad geckodrive (G202) so I made the plunge and replaced all of them with G203Vs. That was easy enough. I changed the jumper on the control board from +5V/ground to ground /common which was also pretty easy. When I fired up the machine, I tried to move the gantry from the middle of the table towards 0,0 but it went the otherway. No matter what I input on the console, it will only move towards the other end of the table.
Anyone have any ideas why this is happening?
I emailed Shopbot Support but I am guessing they are busy dealing with the weather.
