Tangent Corner / Re: Making of a spindle

It would be much easier to get an old spindle out of bridgeport or similar machine and drive it with a belt and pulley system on an external motor.

Making one involves a lot of messing about, turning, milling, heat treatment, grinding, and then if you want good running it must be dynamically balanced.

High speed angular contact bearings cost a fortune.

Not for the faint hearted.

Hi Brett,

I have just traced a wire back and the part number is Efector IEB-3001-ANOG

The symbols on it show BN=+ BK=- BU=-/- (looks like a switch)

Its not the power supply side thats a problem its the input to mach break out board that i am not clear on.  do I connect it direct to an input or do i need to add some other electronics so the 5 volt input is not blown.

General Mach Discussion / NPN Proxy switch help

« on: November 19, 2006, 08:25:41 AM »

Hi All,

This Boxford I am converting has NPN proxy switches for homing, they work at 24VDC black and brown are power and blue is signal.

My question is this can I connect them direct to an input or do I need to convert the signal in some way?

Thanks
Graham.
