one way only movements
recently I replaces my MKS. GEN V1.0 BOARD & MY MKS TFT28 V3.0 After flashin with the older 201 april 16 malrin in my arduino. I get no movement in any negative direction. I get movement in the positive directions but no return. I have tried checking all wiires and connectors. What am I missing? Please help. I have new motor stepper drivers coming but I want all else up to par. Someon please leae me some kind of way to identify why this will not move in the return or negative directions.

If I move the y table below it will move it in the right direction. I also can move the x axis as long as it is in just the positivge direction. .
I recentely had this machine given to me because it had stopped working. I found the power supply was out. I replaced it Then I had no screen when it was hooked up and bought a new mks tft28 touch screen. I got it on and flashed it with the latest version in the JG wiki and nothing would move.
I got a new board. MKS GEN_L VG1.0 BOARD.
Then I checkeck ed the voltage on the motor steppers. All seemed in good ranges. It moved the z axis up and I noticed the axis was not level and then noticed that it did not have the 4.mm set screws in either. I got those yesterday. I finally checked all the wire plugs and put it all back together. I cannot find a loose or unplugged connection. I have learned a lot thru the videoes of various people. I looked at the basics on the board.
Ihavre ordered and await new stepper motor drivers. TMC2208. I am now wondering if i need to get new harnesses for the whole the thing.
