Testing connections before power-up

Post by WillAdams » Mon May 20, 2013 12:13 pm

Is there a basic write-up of this?

I looked, but couldn't find one. I think I've tested things okay, w/ an old multi-meter of my Father's, but I'd appreciate a solid set of instructions from someone who actually knows what they're doing along w/ tips on what / how to test and _why_.

To test your connection of the stepper motor. You can measure between two wires. If you got about 2-5 ohms (depends on motor type) then you have a coil. If you have infinity then it's no coil. If you can't find the second coil then you have a broken wire or coil.

For the limit switches connect both end to the multy meter and set it to diode test. Operate the switch and see if the multy meter reaches 0. The switch is connected correctly. If not find the C(common) on the switch and the NO(normally open). These pins are the one you want to connect to your board.
