That video definitely eases my fears ;). I was able to use a thermocouple at work and the thermistor is reading the temperature correctly. I'm still seeing smoke, but now I have a broken thermistor to replace (unrelated to the smoke, I over stressed the leads when working on the hot end). Which ...

Thanks! I start the PID tuning, but once the temperature gets to about 140C, I start to notice smoke. I've tried this twice and both times I've had smoke, so I've cut the power before letting it complete. Power to the hot end was only applied for maybe 45 seconds each time. I'm hoping to give it ...

I just recently purchased a Rostock a few weeks ago. I'm now at the part of the build where I heat up the hot end for the first time. As the temperature rises I noticed that smoke starts to come out of the hot end. It's hard to tell exactly where, but from searching the forums it seems the resistors ...
