The log says echo: cold extrusion prevented when trying to move the stepper motor. As we all know, it is not advisable to extrude filament if our Hotend is not turned on. So, you are trying to extrude when the thermistor on the hotend is reading too cold (not sure what firmware you are running, this is a value in the firmware and it has not always been the same). There's a temp fall error catch that will disable the extruder power in the event of a drop off (like if the thermistor fell out) Once it gets below the safe extrusion temp it won't allow it to extrude anymore. Clean the Nozzle. So far, I’ve gotten pretty much everything to work, and I’m on the home stretch except I can’t get it to extrude without having to heat up the nozzle (just dangling off too the side to prevent other errors the machine gets when it’s not connected).
