Stepper motor

Unfortunately a driver replacement won't be possible for a V3.51 board. these boards have the soldered on driver chips that were discontinued many years ago. SB bought up as many as we could back then, about a year ago now our supply ran out.
You would require a V4G or RBK upgrade/controller replacement. support@shopbottools.com has you covered on this one

That’s what I was afraid of! Thanks everybody for your input. Anybody have a board for sale?

does that board have 5 drivers on it

I was thinking about turning apart and seeing if


You do not want to ever take apart one of those motors. The manufacturer puts them together and THEN magnetizes them with special equipment. If you remove the rotor it loses much of the magnetism and the motor will never have the torque that it is supposed to.

If you do have a fifth channel/unused channel and the channel is the issue then we can try this channel rather than replacing the board. It just needs to be set up as the appropriate axis, to set it up for say the X axis you would need to set the dip switches for that channel (labelled DIR/STEP - 1 through 5) to 1 and 1. For X2 you'd use 2 and 2, etc...
