I’m not very experienced with the Taz 6 or 3D printing in general, but I support three of these things and manage them with OctoPrint. After three months of trouble-free printing, one of the Taz 6’s has begun to throw thermal errors, but the error does not indicate the problem’s source. See below for a log snippet.
Besides testing the bed’s and toolhead’s thermistors and checking to make sure all connections are secure, what else can I do to diagnose the problem? These printers are pretty much in constant use, as we offer free printing of models for students, and I’d like at least to attempt some troubleshooting before giving up, requesting an RMA, and then being down one printer for a few weeks.
Thanks for whatever suggestions anyone may have to offer.
