Thanks!

"Well THERE'S your problem!!!!!"

basically fell out of the shrink wrap tube.   re-solder and off we go. no more spikes when moving or wiggling wires.  Once again you guys were awesome!   Thank you for helping me with this!

I did notice at one point that RH dropped the temp in the manual control down to 184 when i set it to 205, but I raised it again and its been solid.  Other than that I was moving all axis, wiggling every wire I could find and absolutely nothing.  Blowing on it makes the temp jump 6 to 10 degrees in either direction, but once it recovers the line stays solid.  Going to attempt a print and see what happens.

uuuhhhhhhh   ok.    Maybe loose connection was this issue.   Again,  thanks all of you for your help.  You guys are the best support I've ever seen in a forum!!!!!

Yeah its still doing it after the calibration.  getting alot of this  "23:21:20.943 : echo: cold extrusion prevented".  I have no idea what to do now about this.  Extruder is definately not holding a constant temp.    what should the temp graph look like?

Once the electronics see a temp below 160C it will issue that error same thing when it sees a temp greater than 215C(or whatever it is..) it issues 999 error.

You most likely have a bad connection at one of the IDC connections on the printhead but for sure a loose or faulty connection relating to the printhead thermistor

temp is fluctuating about 50 degreese.    my layers are seperating (i believe its called delaminating).  ive run the hot end calibration, checked the eeprom and made sure the changes were in there.  im at a loss.  is my hardware broken?  or is this still settings?  The only other thing i can think of is i bought a longer usb cable ( 10 ft).  but i had a 2 hour print come out great the other day.......   then everything went to hell.  Anyone from solidoodle wanna chime in?

Thanks for the info, going to try this as soon as possible.

The fan on the extruder will not cause this error although if it stops it can cause filament jams, it is the same cheap fan that come on $2000.00 computers... you can usually get some oil on the fans bushing by removing a sticker to get to the shaft or change it out with a more costly ball bearing fan... however even the BB fans are not lasting very long in my experience these days, might have something to do with where they are made or lack of QC.

     Now I'm thinking that this is some kind of overheat issue but I don't know why, I've read people have their printers set to 205 and 210 (yes I know it reads 30 degrees less than actual temp)  and when I try to print at 190 it seems like the layers don't melt together as well.  once again thank you for any help you can offer.  Going to continue printing and try to see what temp setting it stops Overheating (???)  at.  maybe I'll have more info for you.
