Bridgeport mill and back gear spindle reversal
« on: December 21, 2009, 06:54:01 PM »
I have a Bridgeport milling machine and how can I tell Mach software to invert the spindle direction in Back gear using switch hooked to the lever

I am not sure if checking reversed in the pulley setup page will do that or not, if not then you will need custom M3 and M4 macros.

Do the Macros run with in the cw cww button or does the macro run from the m3 m4 code from a program

To be honest I am not sure, dont use the button myself as I have external buttons. Will see if I can test it out, just have to think of a way LOl

Looks like the Spindle CW button ignores the M3 macro and does its own thing, nothing stopping you from putting VB buttons on the screen however. Something like
If GetInput (1) Then
Code ("M3")
Else
Code (M4")
End If

Should work for you, the above would be looking at input 1 for your lever switch, if it was seen then it would do a M3 and if it wasnt it would do M4. You would also need another button to do the M5. In fact you could probably integrate it into the same button by looking at the Spindle on LED and doing the M5 if it was on.

I did notice in the spindle pulley set up i can set  pulley 1 for high gear and set up pulley 2 for low gear with reversed box checked but I have to set the pulley number manually

You can do it from code if you look at the thread that Overloaded has just posted.  http://www.machsupport.com/forum/index.php/topic,13484.0.html

btw...according to TFM the above is absolutely correct. The REVERSED checkbox is there for this very purpose.
