G2s Pro send G1 X0 Y0 issues

[BRE FRESH]

I recently built a G2s pro and I've been able to get the G29 command to work but when i input the G1 X0 Y0 command the printing head just keeps moving up and rams into the end stops. It is much similar to this video

My endstops are connected properly... I have no idea whats going on???

Did you home the printer before you send this command? If I didn't home it then no matter what I click it will move all the axis up to the endstops.
