    Exclamation Tiny New "TB6600" Stepper Driver Heatsink

    The (already too small) heatsinks on the cheap "TB6600" stepper drivers have recently shrunk down to almost nothing. Old (left) vs. those received within the past week from several sources.

    They still look OK for a single TB6600 driver. Unless the power chip is overheating, I would not worry about the "new and improved" heatsink.
