hello, i recently installed the carve tight and the 907 upgrade package and have went thru the guide several times and everything looks good. but now when i try to run a project it comes up with a poss board removal error or please close cover or y axis stall. i never had any of these before i made the upgrade but im not sure what i could have done wrong. i talked to cw and they had me check a few things but they ended up being puzzeled they are supposed to call me back but havent done it yet. hopfully someone has some ideas . thank you
