Blue screen Lowrider CNC

Hi,
I am currently buildong my Lowrider CNC but i have som problem with it …
All seems to be working for a minutes, i can move the head but after a minute, the LCD turn blue and i couldn’t do anything … I have a Archim 1.0a and the basic LCD from V1 engineering…

What could i do ? I don’t understand what is the problem…

And it do not crash when i connect it with my comuter … really weird !!

Maybe it is a power issue? Although I thought the Ultimachine boards didn’t use much power from the USB.

Do you think it could be the bridge i done ?

I don’t know what bridge you’re talking about.

The bridge to make the link between the the board ( archim ) and the alimentation …

Check your cables. It could just be a loose cable going from the LCD board to the controller.
