Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 9 years ago
The thermal runaway can be any of several things. Did you recently update your version of Marlin? If it looks like your temp is dropping to zero BEFORE the thermal runaway, then it could be your sensor coming loose or an intermittent wiring issue. If you are running one of the latest versions of Marlin, it can be pretty common for the temp range to be set to narrow, which will trigger a falsby Bert3D - Prusa i3 and variants

I have read 60 - 70 posts in this thread and now I am more confused than ever. Is there a step-by-step wiki or post I can follow to get auto leveling up and running with what I stated above?

Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 9 years ago
If the endstop is on the left, it is at the min position. That's what makes it better, because, it marks x=0. Just put it in the min plug slot. You may have to set it in the firmware too. I can't remember the default in TheRippa's code.by Bert3D - Prusa i3 and variants

QuoteCyril QuoteBert3D The extruder fan should be always on, or you will get nozzle clogs from heat rising too high up the heat break tube towards the extruder. It cools the extruder and heat break.

Oozing around nozzle? Did you hot-tighten your nozzle and the heat break tube/barrel into the heater block? Don't assume the hot end comes assembled correctly. Mine wasn't, and I had similar problems. Before using the printer, you should heat up the hot end to around 240 and tighten the nozzle into the block, then tighten the heat break tube down firmly against it.
