diagonal movement the axis

[DANIEL PALOMINO CUESTA]

The manufacturer zonestar I bought a z9f-a printer from them I have tried to start it but despite everything it does everything it has to do but its movement of the axes is not adequate. I have checked the engines and I will send you a photo of both. I have checked the connections on the board and everything is correct. The problem in question is that I can't get it to go only horizontally and not also vertically if you send it a horizontal movement, whether it be to one side or the other. the tires are also correct, at least the position and path of both the x axis and the y axis. I would appreciate your help. I am managing it both with cura and with the LCD of the printer. The board you have is a zrib_v6 The firmware is the one provided by VDS version 1 although I have also tested it with the most current firmware that is posted on GitHub.
