Thank you Barry and vicous1 for your reply i have cleared the nozzel from the wrap tape and the remaining ozed pla the nozzel seems to look just as you show in your picture the spacing is about the with of an exact o knife opposite to the cutting edge IE the back of the blade. I tested the heater block for continuity and it does have continuity. I continued by checking the heater sensor ie the white wire item they do not have continuity on its leads. Is this last one supposed to have continuity?. any thoughts on how to repair if possible?
