Mr Hood

hello, Thank you for your reply. It comes with MACH3 ready and it is a pc based, We have our own pc as per Mach3 requirments.I purchased a license also.

Now as per guidelines i am trying to conect my pc to to machine with 25 pin chord.

i am able to set the axis  somehow i am able to start the spindle but i am not able to control the spindle. When i give command m3 or m4 it moves only anticlockwise,

My motot is SINGLE PHASE

Please help me to set my PC As per required settings.I would be thankful to you.

If you bought this machine new then ask the supplier for the xml file. You may already have it if you got a CD with Mach on it.
 Without knowing how the spindle works I cant really say how to set it up, if you had documentation of what hardware is used then it could be worked out.
If your motor uses relays to switch on then possibly both relays are set for the same pin and should be set for two different (1 for M3, 1 for M4) but again without knowing the hardware on the machine its impossible to say how it should be set up.

Hi, I'm struggling to make sense of what's happening with my spindle control. MACH4, Microsoft XP, Parallel port and Darwin. I see the pulse rate affects the outcome on my speed? Is that right? My set up is on a 3040 chines mill with the router that comes with the original unit. 300 – 8000 rpm. Putting a taco on it I seem to be getting a range from 5700 to 10830 rpm, and that's trying to control it via Darwin. 0 gives me full speed and 20000 gives me 5700rpm. So from Darwin I get a reasonable range. MACH4 I'm lost.  The on/off works, PWM seems to work but not full range and same effect with the min/max freq setting. In the freq range I used 0 to 20000.  When controlling from the GUI, there is a limited response from the slider 50 % to 150%, which also has the opposite affect i.e. 50% runs faster that 150%? It put values in at the top when running, 150=50%, 300=100% and 450=150%, but I can't work out where its getting the 300 from? The PWM set up does pretty much the same. ???

You would be better posting this on the Mach4 section as this section deals with Mach3 for the most part.
