Another motor meltdown

Heat sinks went in on

May 20 & worked well for a few months. Then came another case of a screw coming loose, the encoder going out of alignment, & the motor stalling. It quickly overheated & melted the PLA, feeding back into the stall. The heat sink was initially only slightly warm. The good news is the heat sink quickly got hot. It definitely took out some heat. The motor cooled down more quickly than it did without it.

The lion kingdom stopped using PETG because it's heavier than PLA & it requires enormous heat to print. The melted PLA has never permanently killed it. What's really needed is a screwdriver which can tighten the screws in the field. Those screwdrivers are gigantic.
