HI,
I have MKS Gen V1.4 board brand new. Using a4988 steppers, 42SHDC3025-24B steppers. All wiring is correct and verified across sources and spec sheets. This same hardware all worked (but using different board) in the exact same configuration using Ramps board prior to the changeover. Zero movement or even a hint of movement from the motors. All else responds well in pronterface. End stops all reporting exactly as intended, heat good, fans good etc. Temperature of stepper driver heatsinks good on idle. When I do a test print for example, pronterface says all started good, heats up ok then nothing. I don't know any codes to send to pronterface other than m119. When I click the graphical motor directions no response from printer and the delay on the pronterface status log is about a few seconds before any text appears but still no movement. No heat change on driver heatsinks etiher at that point. M119 does return correct status instantly with no delay though.
I used board 33 on Marlin. What am I missing? Please? I have been trying for a week now without wanting to bother anyone, but here I am...

hot end and bed both power up and heat up perfectly. Pronterface and lcd both show correct values.
lcd works with/without usb.

Unbelievable! Out of 10 drivers...8 are dead. 3 so bad that they suck so much power that the board goes dim. So, I can at least calibrate my printer by moving the two I have on hand (turning off all power before moving them ). I guess I need to order more. Any value to ordering different kinds? These are a4988 knockoffs. Does anyone recommend a different kind? And can I mix and match? Perhaps use the a4988 for my extruder and z and then something fancier, quiter etc for the x y.

I'm thinking that 5 of them were failed from my last board that I shorted out because something dropped on it.
