I have an ER1 robot arm that dos not work. by mistake I crossed the polarity of the power cord and a little puff of smoke came out of the circuit board. I have looked it over and cant find any visable burn, I might sell it if anyone wants it. I am also willing to buy a functioning one, I thought about converting it over to servo but if I go that route I might as well go all out and buy a 5 axis arm. If anyone can help with repair or has another gripper please let me know.
