First time build - Steel Frame CNC Router

[JAZZCNC]

Please if you get the chance could you give the updated schematics a final once over? Only additional thing I changed further to the suggestions was earthing the Spindle to the VFD rather than star point as I guess will make wiring easier.

Ok few small details.

The Green wire you have coming off Stepper B (-) I'm hoping is representing Shield going to earth and your not actually taking B(-) to earth.? If correct still only earth at the Controller end not the Stepper end.

Don't need 24V to outputs 0-3 because your not using any. Your only using the onboard Relay which is output 4 and doesn't need 24V.

Fans can get away with sharing fuse. I use 2 x 12v wired in series because are cheaper and easier to find.

With the 24V for Controller I/O save your self some wire and jumper between the Pins. Don't need to run separate wire to each pin. (See pic)

Don't forget to send Earth to Machine Frame.
