24vdc amp power supply knock down to 5VDC@24 milliamps?

Jeff,

If you ever decided to do rigid tapping with your machine the r.p.m. feedback would become a critical factor and would need to be tracked precisely to a small fraction of one r.p.m. in order to make any semblance of a thread let alone an accurate one.

Also if your tool changer used keyed toolholders your machine would need to keep track of the key position in order for the tool holder to fit into the mating spindle.

Spindle position in relation to the key would be critical.

There is a reason why I suggested an encoder................................

is mach3 or mach4 able to keep angular position on the spindle? or do you just program a different axis for your spindle?

Use a macro to swap the A axis for the spindle.

I don't know the answer to that question. I am going to make a new motor mount plate, mount my 2.5hp Lee's on 3 phase motor on it. I am going to use my Hitachi wj200 vfd to run it. I will then be able to do rigid tapping.

DO THE HOMEWORK

Irregardless of what three phase motor and VFD you decide to use, the VFD does not precisely keep track of the angular position of the spindle.

An encoder keeps track of the angular position that is why many commercial machines use a servo!

Fitting a encoder to the motor or spindle allows the software to accurately monitor spindle position.

I am tired of shoveling snow.

I power my ESS board with this 5V AC-DC power supply.

I have the supply AC side connector simply connected to the input of my 48W power supply. its small, works well. i 3D printed a cradle to allow me to easily attach it to my enclosure.

its another alternative than trying to find a 24V-5V step down.

Yes I am going to make it work as I am determined. We have had maybe only 4 inches of snow total this year.
