That's going to be some machine looking at the quality of your work so far.

Hi David,

You do need drivers for your stepper motors.

General Mach Discussion / Re: creating small circles
« on: November 21, 2009, 04:52:32 AM »

I have the spindle output hooked up to a pneumatic air gun that dispenses glue.  The glue is going to form the .060" diameter circle.  the problem is the blasted spindle dwell.  When the M3 is called out, the glue comes out for .5 seconds and then does the circle and then comes out another .5 seconds after the circle is done.

You could reduce the delay from your 500mS to 210mS quite simply by setting mist coolant (M7) to the same output# as your spindle (under ports & pins/spindle setup) and setting the delay as zero then with a GCode editor modify your code to block replace the M3 command with M7.
I wonder, would this be a large enough saving in execution time ?.

If you are using LazyCam then it will create the Z axis leadIn's unless you set the 'LeadIn size' to zero or uncheck the 'LeadIn on' box. (under the 'layers' tab click 'layer leadin settings').

You can confirm the address of your second printer port from:- control panel/hardware/device manager/ports/properties/resources.

Suggest you wait until you have your new BOB before going any further. Have patience my friend.

The completed circuit board, well more of a terminal board really as just about everything connects here. The board contains 3 voltage regulators (12V, 9V & 5V) and the logic IC's to drive the indicator LED's.
