I just tried to turn on my printer and the lcd screen didn't light up. I thought this was weird, but the fans were running so it ha power. So I continued to see if my printer would connect to repeater host, and theres nothing. I then tried to see if my board would connect to Arduino. It didn't. Any ...

So, I bought a G2s printer around january and i built it it is all correct. Today I finaly figured out the coding part of it. However at the begining of every print the nosle crashes into the bed and wreaks my tape. So does anyone have any idea where I could be going wrong.
