HB2 Stepper Heat Sinks in the Rough

HB2 Stepper heat-sinks CNC rough milled

These are the four spacer/heat-sinks I am milling for the HB2 router. All four heat-sinks are rough milled on both sides. I flipped two so both sides could be seen.

Total run time so far is about 1.5 hours each. So with setup and clean up and taking pictures, this is about a full days milling work.

I also spent as few extra hours in the morning with RhinoCad making some last minute adjustments for the final runs. Mostly to make sure I don’t get any of the early versions mixed in with the final edits. I was also to reduce some of the run time through better tuning.

The fin cutting is going to take about 4 hours per side, so there is at least four full days of work left to do.
