Title: g2 stops program when running
Post by: Luslugger on November 28, 2010, 04:25:11 PM

The n211 G2 line stops the feed.  What is happening?  How do I change?
The n36 g2 is a spiral. same questions?

Probably needs a J. Is there an error message?

I added a J0.0 to the line.  The code stopped at the same line.

THe  code runs here.  It does not do anything constructive but it runs.

What do you mean "does nothing"?  My Mits m86 controllers have been running this code for years.  I ran this code yesterday.  I am trying to back plot the code I write by hand.  Since I already own the Mach3 series, I prefer to use Mach3.

What is the P3 and P1 for in the G02/3 lines on your old control, I don't think Mach3 will like them for a start.

What I meant was it does not appear to acutally be part of a program that actually cuts something.

Here is a shot of the toolpath as drawn in Mach3

That is what I would like my Mach to look like.  The circles don't look on the same centerline but they are.  It is one interpolated circle with another interpolated spiral in the center.  Did you get that jpg with software or a camera?

That Jpg is a screen print saved in PAINT then trimmed and saved as a JPG.

As Graham mentioned as well Mach will not process the P values you used in the arc

In the inside circle you can see the spiral that was generated by the P = NO. of turns.  As a backplotter I have been seeing the P for spirals for several years.  Maybe the control will not output the P to the steppers.

I don't think MACH supports the P parameter.
