Re: Problems with new sherline mill/camtronics system

Thanks for all your help everyone. I found the problem. I had
connected the motors to the board through some Anderson PowerPole
connectors. One of the pins was not pushed into the housing all the
way so it wasn't making contact. The weird behaviour while doing
moves along the y axis threw me off. After following the suggestion
of moving one step at a time I found that the y axis would move
one step right, pause for 3 steps and take one step left. When I
checked the wires on the camtronics board I found that each coil
was about 4 ohms except one on the y-axis which was no connection.

After I pushed the pin in until it clicked it worked fine. I did
the wiring late last night so I was pretty tired and I missed that
one.

thanks,
Glenn Pipe
