Motors not working

[imbence]

Hi,
Just got the MKS Tinybee with an MKS TFT35 screen and A4988 drivers. I connected them up with 3 motors for testing but I'm unable to make the motors move with the default firmware as it came with.
Can someone help me with what could be the problem?

I have the same board, but not the same screen, so I can't help you fully. I would connect via USB and use Pronterface / Printrun to move the motors using gcode commands.

Some things to keep in mind:
A lot of stuff on your board are not connected and that might generate errors preventing motor movement.
That screen is often given as a set with a different board, I'm not sure how compatible it is with Tinybee.
As far as I know, Tinybee is shipped (on new orders) empty, without Marlin installed. Did you configure & upload it correctly?
