Updated software to 3.8.46. Have a few things I need to work out. Most troubling for me is that the Z Axis jogs up an inch when I click OK after starting the Spindle. A lot of my work is 3" tall, requires a 3" End Mill, and 1" of travel clearance. That 1" can make it hit the top and crash so I need to find how to turn it off.

Any ideas?
