My feeble knowledge of electrical has me stuck.
What I have: Gecko540, 48vPS, Mach3, 110v 1ph motor w/ 110v/32v mag. contact relay and 32v transformer.
Mill momentary on/off switch, which has 3 wires. Blue to the ON term. of NO contact. Red to the OFF term of NC contact.
And Black wire that goes to a jumpered common terms. in the middle of sw.
The 3 wires go back into the mill column connecting to a strip.

What Im doing:
Installing Side 1 estop NC button to 540 term. #10(charge pump) and gnd.
Side 2 estop NC to common wire from the (blk) wire to common term. on the mill"s momentary on/off sw.

What I need done:
Have Mach3 spindle control turn motor on/off thru Output #1, term #5 (pin17)
and also have the ability to manually turn on/off mill w/out Mach3 (not in control)

Was thinking of putting a SSR relay in between the common(blk) and the term. on side(bl) of mill sw.
Have Mach3 output 1 provide power to the relay coil.

Make sense ?
Have pics, etc if needed.

Took awhile to figure what this meant. Is SW1 a momentary switch ?
If it is, the existing ON button (normally open) could be used in place.
Im guessing, in place of the existing OFF button(normally closed), the estop NC would be used instead ?

About relays, I have a SSR 110VAC/24VDC. Will this work w/ 5V ?

NO.
This is what you want

SSR 25DA Solid State Relay 25A 250V 3 32VDC4 380VAC for Temperature Controler | eBay

SW1 would be a SPST switch. This is your manual on/off switch

If you want send me a PM with your mailing address and I will send you the transistor and resistors.

Thanks for the offer. But I dont understand this method.
Do I need to find what wire from the original ON/Off momentary switch goes to Line in the back of the mill ?
I havnt traced the wires yet, but they somehow go to a magnetic? relay.
Upper left- Rd, Bl, Blk on strip connector come from ON/OFF sw.

I wouldn't even use the existing contactor/starter.
But if you really want to use it. All you need to do is interface the C10
to switch the control voltage to the contactor.
How to wire this depends if the coil on the contactor latches on, or not.

Why is the contactor/starter not needed ? and what is a C10 ?

[Mzones]

I guess I got a little confused here .
Let me rephrase that.

As for not using the existing contactor. see my original schematic.
The SSR I suggested replaces the existing contactor.

Since then I did some changes to allow Estop to turn off spindle motor
( either Estop switch. or Reset button in Mach3) When using the manual switching.
and not turning back on, by just resetting Estops.
This newer design fixes a safety issue.

Personally I would use the contactor for E-stop/safety purposes, you could always wire the SSR after the contactor for Mach M3.
If you did need the contactor to latch, you could use the centre unused phase contact for a retaining contact if there is no auxiliary contacts on the contactor.
Software and SSR control only of a spindle is not considered safe, if something happens in software etc, the spindle could start inadvertently.
It depends if you want to conform to code etc.

12114relay.bmp looks the same. Where did you update ?

I got the transistor and resistors, push button today.

Here's the progress so far.
This is still a work in progress.

Nevermind- ok

[Mzones]

Already caught that.

Haven't figured out the resistors values yet.

I will work on a explanation of how this works.
Also will test on a BB.

Always use the contactor. They are so much better at protecting you than software and you already have it. An open set of terminals on it could trigger your estop within Mach but in reality all power to everything downstream should have been stopped when the contactors latching was broken.
