Hi Bill,

sorry to say the Orac is a lathe, I don't think your code V-Carving is any use to them.

Is all the single phase electrics coming from the transformer or from the wall socket?

Take a single phase from the converter and use it to drive the other electronics.

The wood frame did not allow the phases to cross, metal will.  That could be your problem.

Not just a pretty face, or is that not a pretty face.

In your program enter F120.  this will double the feed to 120/units per minute

Add the red bits and it works, I don't know what has changed in Mach .037 but I will have a word with Brian about it.

General Mach Discussion / Re: G76 pitch

« on: March 04, 2008, 12:20:37 PM »

Is the thread out of pitch all the way down its length or is it just at the start for a few turns?

If the pitch error is at the start only :-

What can happen is the cutting load of the tool can stall the spindle for a split second and throw out the pitch.

Also you have to allow for acceleration of the tool, in most cases 6mm (1/4") depending on the spindle speed and reaction time of your machine, the heavier the saddle the more time allowed.

If its all the way down :-

Your machine calibration is out.
