SOLVED: MINTEMP triggered, system stopped! Heater_ID: 0 (Printer randomly stopping mid print)
I solved a problem I was having with my A5 stopping mid print randomly and just thought I would share my solution to add to the list of things to try when having a similar problem.
After doing searches and trying several different things to solve the problem with no luck, I decided to start pulling the printer apart and checking out with a multimeter to see if there were any problems perhaps with the mainboard inside. But in the process, I started removing the conduit that shields the wiring that goes into the extruder head unit. (see picture).
Inside the conduit there are a couple of white connectors. On my printer, a wire had managed to work itself loose from the back of one of the connectors somehow. Immediately I said to myself, "now THERE'S your problem." I repaired the connector, put the printer all back together, and 3 prints done now with no problems.
