I have a Keling 382 Oz motors with kl 4030 drivers and a C10 break out board. This is a 3 year old machine and has been working great until now, so its not a wiring problem I don't think. I can only get the X axis to jog 1 direction, no matter what arrow I push it only goes one way. I switched motors with this driver and get the same results. After intensive research and reading I figure that its either the KL 4030 Driver, the C10 BB, or a Parallel Port problem. Could someone please help me narrow down what the problem is? What kind of voltage should I have leaving the BB towards the drivers, then what voltage should I have leaving the drivers. I have a hunch its the BB but need to be positive before I order a bunch of parts I dont need. Thanks in advance.
