So I have a small fleet of 3D printers at my workplace, most of which are Makerbots. They vary in age and in model (Replicator 5th Gen, Replicator+ Replicator Z18). I have tried to update the firmware, but some of them are old enough that they are stuck on a previous version.
I keep getting Error 57: Heater Temperature Sag Triggered (photo attached), and the Makerbot support page isn’t particularly helpful.
I have tried replacing the extruders with new ones, taking apart and cleaning the extruders, using extruders on different machines, using Makerbot Print and Makerbot Desktop, and I have still run into this error on every single printer. Sometimes it happens once in a print, and sometimes its seven or eight times in the span of half an hour of printing. In general, the prints produced until the error appear to be just fine, save for an occasional small blob of filament.
Any advice on how to fix this error or at least minimise it? I would really appreciate some help.
