No movement

On first boot I tried to switch modes and marlin would not load. I switched back to big tree and tried to move the steppers and got no movement. It is the firmware that v1 shipped. I tried to use pronterface but my computer does not see the device (the usb led lights). I also wired 2 end stops but don’t think this firmware supports it. It is wired in series using a Y board found on Amazon. Any suggestions?

I figured it out, I didn’t power the motors. I still have other issues though I think mostly related to the firmware.

Which issues?

It was a little laggy but I adjusted the belts and got x and y moving smoothly but z turns a bit and stops but continues to make noise. My theory is that it is locked on place to hold position. I read some posts today and adjust the feed rate to 4mm (10 just before) but it made no difference. Also the TFT won’t control the movement and and it won’t switch to the marlin side. I extended the bed area to 580 mm both x and y that solved a few issues.
