Problems with the bed

[salgarfa]

Good moorning, I have some problems with the printer, one of them is the displacement of the bed, as you cas see in the photo. And sometimes the printer stops with the missage error: mintemp.

I think you can check the voltage of the driver(A4988) of Y-axis, I guess it's a little low, increase it to 1.0V to have a try.

Hello, I have return to try with the printer, I have tried to set 1.0V but I can't, the voltage is always 0V or 4,8V. Perhaps I need a new ATmega2560 because mine is damaged.

What about the other drivers? I think is the Y-axis driver broken.
