I have been having many problems with my machine , y stall, z stall, clear rails, tracking , carve 95 % of the project and then just gouge teh wood ( 3.5 hr carve ) and i,m sure i forgot a few . i talked to carvewright people and they said reformat the card , upload the new version , clean machine again , check all connections , i have done all of that , but while cleaning the machine the lil green card on the bottom has a brown " thingabob" i said that because i dont know what it is , but how ever it has 2 prongs on it and one of them is broke , i,m a jet engine mech not no electrician , i know it should not be broke now i am wondering if i broke that during the cleaning , or did it break while the machine was running and is that what is causing all of the problems , thanks for your input .
