Manually starting spindle with edge finder

[diemaker76]

Hello;
Machine: VMC 15XT
When setting fixture offset how do you start the spindle manually to use a edge finder? I know there is a start/stop spindle red button, after all the steps with setup and such as setting RPM. The spindle turns slowly and stops and then I try to press the above mentioned button and nothing happens.
Am I missing something or is there a problem with my machine?
Thanks,
Bob

Before you start make sure you have a spindle speed set (S800) in MDI mode.
When you want to turn the spindle on hold down the shift key while pressing the red spindle button.

When the spindle turns slow and stops is that because you did a spindle orientation (M19)? Otherwise I don't know what would cause that.

I use S1500 for edgefinder

Thanks!
Will give it a go.

I don't know where or even IF it is written, but for some reason 800 RPM was the number taught when I was in TS.
Anyone know what RPM Starrett suggests you run their edge finder at for certain?

I take that back I just looked at the msc websit Starrett says 1000 rpms or less I've just have alway used 1500 rpms with out a problem maybe I should rethink that one

Thanks again!
The shift/spindle on method works great.
Also using S800.

I'm gonna make some high-performance edgefinders that go to 4000rpm and sell 'em on Ebay!

What do you guys think of my new slogan.....

It isnt the RPM that rotates the jog wheel .0001 at a time and watches the edge finder to see when it pops off :-)

Diemaker--
I usually teach using 1000 to 1200 RPM for the edge finder. To start the spindle manually at any time press and hold either SHIFT button and then press the SPINDLE button and the spindle will start. Pressing the Spindle button alone will stop the spindle (except in Auto mode)

Hmmmmm...... A high speed motor to drive the jog wheel.....I'll have to modify my slogan......and sell 'em as a package through Enco....
