With my new BOB (HY-JK02-M) I've managed to get a motor to run and run smoothly, but only in one direction. (Once I set the parallel port pins to match the docs settings for Mach3.) I tried swapping the wires on one phase, ran quite rough and still only one direction so I swapped them back. I've checked the connection tightness multiple times on everything, all screwed down tight.
That's not the weird thing. What is effed up is that when the motor is running if I pick it up or move it, it stops running. Doesn't matter if it's laying down or standing on its back end, if it's picked straight up or allowed to rotate around its shaft axis it locks up and squeals. Tried two of the three, both do the same thing. That is going to be a bit useless on a mill table where the X-axis motor is going to be moving back and forth. ------------------------------------------------------------------------------ LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.
