I'm having a problem with my Z axis config. I have the max velocity for
that axis set to 13 (mm/sec) which is 780 mm/min (slowed down until I tune
it). If I do a G0, it moves at 780. However, if I jog (z axis only), it
tries to run at 4800mm/min which is the max velocity of the x/y axis.

OK, this is catastrophic! You can't even run servo hardware like this, as

When using a router as a spindle, there are several things to consider.
First, the routers are air cooled. This means if you run the router at
lower speeds, you have to watch for overheating. Secondly, the airflow is
directed from the top of the router down towards the work. This means it

I remember seeing a YouTube video of the guy from BuildYourCNC.com
making a dust collector shoe for their machine. It addressed leaving
room for cooling air for a router, but focusing on collecting the dust
from the cutter.
