General Mach Discussion / Re: Mach 3 wont start the spindle

« on: January 19, 2012, 07:56:14 PM »

Hi Bob

Not sure what I have done but the spindle now works with the toggle button.  I have run a very short gcode and for the first time the spindle ran up.  Thank you.  The first time i entered M3 s1000 in the MDI screen it worked, since then I have tried a number of times and i just get the error message saying a limit switch has been triggered - no limit switches have been hit.

In answer to your question, I only have three stepper motors and the spindle - no other devices.

Hi Bob

Just had a local electrical rewinds co out to see the control box, they say it all seems to be operating fine.  They found a digital counter on the main spindle control board and assumed that this would need to change from 000 to 001 or something to start the spindle - therefore , they came to the conclusion that it was waiting for a input signal to start the spindle.  They checked the spindle and all ok.

Sorry i am very new to CNC - can i ask "what xml file and were do i find it?

Thanks Ashley

Hi Bob

I have done some investigating last night and the results are as follows:

The spindle is not branded, it is a water cooled (seperate pump so the cooling works) GDZ-80-2.2 dia80*210   220v - 2.2kw 8A     400hz  2400rpm

I checked the pins at the end of the parellel cable and I have a constant 4.9v at pins 1 - 9 - 14 - 16 -17

Settings in Mach3:   Motor outputs are set to:  step pin 16        Dirpin 17
                             Output signals:  enable1:  port 1  pin14   
                                                     enable2: port1   pin1
                                                     output1:  port1   pin16

I have power into the spindle control panel but no power at the output leads to the spindle.
pwm base freq 1
minPWM  0

this was set to 10 and 2 but this trips out the system .

If you need any further info please let me know.

Thanks for the reply Bob.
Had a look throgh the lit that came with the machine and it tells me to configure the spindle in Motor Outpits tab to:  step pin: 16 dir pin 17  step port 1 and dir port 1, this is all done ok.  Now I am getting a new message "PWM Bumped to Minimum Setting"  - if i change the PWM setting i can get rid of this message but still no spindle responce at all.  When I press the spindle toggle button I do hear the relay click buts thats it.
Any help would be much appriciated.

Hi
Firstly, I am completely new to CNC.  I have aquired a CNC router that is controlled by mach 3, I have spent a few weeks reading and setting up the machine and have got to the point were I can home the x, y and z axis.  The only thing I cant get to work is the spindle.  Mach 3 starts ( i can even run code) and all the axis work but the spindle does not come on.  I have looked in the diagnistics screen and if I toggle the spindle I get a flashing light that i understand means the soindle should be working. Has anyone got any ideas of the mistake i have obviously made...

Thank you
Ashley
