Spindle speed and left/right direction

[caniggia_100]

Hi,

I have Bridgeport Series II Interact II with TNC 151.

My problem is if there is possible to control spindle (except start and stop - this is working) from the program.

It doesn't matter what speed and direction I set in program, spindle always starts with speed/direction as set with manual
buttons. When spindle switch is set to off, nothing happens.

Is this correct for this machine? Or something is damaged?

Please help.
Pawel.

M3 is clockwise rotation and M4 is counter-clockwise in your programming. I have a Series II Interact 4 using TNC155b, so there maybe some differences. Your spindle speed is set in the program right behind the "S" in your program. Hope this helps and answers your question.

Hi,

This I know, but it has no matter what's in program, i have to choose manually left or right direction, also speed.
i found on another thread, that my machine has varispeed head, and with this model, i have to do this manually. It has no tacho for speed metering.

The interact 4 has a electric spindle drive. It supports M03 and M04. The interact 2 does not. It has the same mechanical vari-disc drive as a series 1 standard. Thus the manual spindle start.
