I have had my tinyg for about 2 years. I took a year off, last year it worked perfectly fine. I plugged it in today to find no movement, a heavy hum from motor one, and the motor 1 light stuck on at start up. Even with everything unplugged, motor 1 is still high.

Also interestingly, I can't seem to find the pairs on my stepper motors. One side has continuity but I can't get continuity from the pair
I find it hard to believe that all 3 pairs of stepper motors would go out at the same time, but I'm not stepper motor nut.

Any suggestions?

On startup, tinyG will energize all motors to hold their current position for $mt seconds, then release. Motors will hum when so energised.

LEDs may or may not light during this, depends on what polarity the drive to motors is.

Motors almost never fail.
Are you sure that the lead wires are not broken?
