Returning to my CNC

I haven't worked on my CNC mill for a while.
This weekend I'm planning to:

• Attach cables to the (already mounted) X+Y+Z+A homing switches (Update: DONE)
• Test homing (Update: small issue to fix with Z first)
• Test my experimented M6 tool change macro for my Usovo ATC spindle. (manual tests worked out) (Depends on homing)

Later I need to:

• Add an M6 exception for the 3d touch probe to be stored in a different location (because it's too large for the pneumatic tool-magazine)
• Find a way to get 10V, so the PWM-output of my PLCM B1 breakout board can control the Usovo spindle via 0-10V PWM because it doesn't have RS485 like my old China-spindle+VFD.
