Sorry it took me so long to reply! I ended up just cutting the ba wire below the flex and soldering in some new wire. Then I carefully took stock of where the flex happens and zip tied the wires to my motor (it does not get hot at all). Hopefully I won't have the same problem again, but if I do I will pull the connectors off the resistor an thermistor and replace all the solid core wires with st

Definitely fatigue in the solid core wire! Just look at the pic and you can see "one of these things is not like the other". E-mailed Lulzbot and they said it "rarely happens", although there is a service bulletin about not zip tying wire to the Z-carriage on their machine. I built mine from scratch and did not apply any zip ties. The wire fatigued right inside the wooden guide. It doesn't d

Definitely a connection issue! Ran a print, paused when the temperature started to drop, then flexed my main cable to the hot end in a few places. Power came back on! Now I just need to figure out exactly where the break is so I can stop it from happening again. Not sure if it was my solder joint (going to guess not likely) or if it was fatigue of the resistor wire (going to guess this was it

Repetier shouldn't be the problem. I have been using it very reliably for a year, and have not done any updates in the last month or so (the printing trouble doesn't coincide with an update).
Right now I'm suspecting a simple bad connection somewhere in the wiring, but I've been to busy to check it. Probably in the next couple of days I'll get to it.
What kind of things was Repetier doing tha

I will check my machine, but I doubt that's the cause. I am using a Lulzbot Budaschnozzle so the thermistor and resistor were both pre-assembled and I haven't seen any movement of either part. Also, if the thermistor was reading low, wouldn't that tell the PID loop to increase the power to bring the temp back up to the setpoint?
Like I said, I will check but I don't think that's my problem. Than

I have a printer that has been running reliably for a really long time. Haven't changed anything, but suddenly started getting a lot of stripping problems in the middle of a print. Today I checked the temperature graph and was shocked to see that the extruder temperature suddenly goes downhill mid-print! Any ideas what to check? I already ran through the Gcode and found nothing strange (no st
