Mt Whitney CNC V2

Sigh, had to press the BIG RED BUTTON

The first test run of my new Mt Whitney code started ok, but the feed rate is a little too aggressive for this birch plywood

At some point the bit slipped in the collet, increasing the depth of cut, and it was all over

BTW, there's something really cathartic about debugging code that is capable of physically destroying the system it's running on... there are REAL CONSQUENCES! Compiler errors are so mundane by comparison ;-)

The goal with this new code is to speed things up, so I experimented with estimating cutter engagement and reducing depth of cut on the fly to keep forces manageable. Reran the clearing pass over the aborted first try and it worked! Ignore the large gouge from the first try ;-)

Went ahead and ran the finish pass over the aborted cut for completeness and I’m super happy. Will look great without the gouges

Success

Mt Whitney at 1:24000 scale, still in the jig on the cnc

If I’ve done my math right, each 1/16” ply is 125’

Same scale as the 7.5 minute USGS map for the Mount Whitney Quadrangle
