Electronics for New Machine + Chinese Spindle + VFD

[JAZZCNC]

For the limit switch circuit Jazz proposes, you should add a diode across the relay coil to suppress the inductive spike, which would otherwise reduce the lifetime of the switches. If you're using them just as limits, not home switches,

Speaking of NASA trained Alians and then one appears. . Lol

I was trying to keep it simple Jon and most Relays come with Diode these days so didn't want to complicate things, esp with Transistors.
Was for Limits only has you know I wouldn't suggest running thru Relay for Homes.

I wouldn't bother fusing the fan - do you really care if it blows up, it's only a fan...

Wonder how many houses and garages have burned down because it's Only a Fan.!!
