I got a "cold extrusion prevented" message every 60 seconds for 7 minutes. Cold extruders are suitable for all scales of operation from household- to small-scale, but extruder-cookers are much more expensive and are likely to only be affordable by larger-scale producers. So starting about a month ago, my printer has started quitting mid print. 2. Warm and cold extrusion processes are commonly used: a. 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. I don't hear any clicking while printing. // It also enables the M302 command to set the minimum extrusion temperature // or to allow moving the extruder regardless of the hotend temperature. , Jo H.

You've not reference your temperatures, so consider to use a test model and print at different temperatures. The A4988 driver has the right voltage at 1. aka "it doesn't work". But I find it a little weird that thermal runaway protection is not triggering, because if the temperature reads -14 then the heater. Also changed the feeder tube and connectors, changed the tip several times. Over time, the nozzle will inevitably get clogged. The long die is used to form the layers of meat-like texture and prevent expansion. Under-Extrusion. This is a good fix for minor skipping issues but may not be sufficient for chronic layer gaps.
