General Mach Discussion / Re: Z axis craziness at program start

Try removing this line:

G28 G91 Z0.

And these two at the end.

G28 G91 Z0.
G28 X0. Y0.

In Mach3, go to Config > Plugins, then click on Config for the UC100 plugin, and you should get a window where you can download the latest plugin.

Do you have the latest plugin for the UC100? You can update it from the plugin monitor screen in Mach3.

What motion controller are you using?
As Craig says, if the machine is moving, the machine coordinates should be changing. If not, something is seriously wrong with your installation.

Mach4 General Discussion / Re: Mach4 using G02/G03 with R Radius

Why are you using R?
I,J,K is much better.
I don't really have any answers for you as I use I,J,K arcs, and I don't use Mach4.

You really should try to cut a complete circle using the R word, and many controls won't allow you to.

The reason is that a single line full circle using G2/G3 +R can actually be multiple different circles. A circle that starts and stops in the same place, with no defined centerpoint, can be centered in an infinite number of places.

G2/G3 +R moves should best be limited to 180° or less.

Excluding the Mach4Hobby folder in Windows Defender, changed it from 20+ seconds to load, down to about 6-7 seconds.

G-Code, CAD, and CAM discussions / Re: Simple G Code question

It depends on whether you are using Absolute or Incremental IJ mode.
99.9% of CAM programs use Incremental IJ. Mach3 defaults to Absolute IJ mode.


Try this:

%
(1 inch circle)
G91.1
G20 G40 G49 G90
G01 X0 Y0 Z0 F2 (SLOW FEED RATE BECAUSE I AM JUST LEARNING...LOL)
G02 X0 Y0 I-.5 J0
G01 Z1
G00 X2
G01 Z0
G02 X2 Y0 I-.5 J0
G01 Z1
M30

VB and the development of wizards / Re: Macro Tutorial

« on: November 03, 2017, 12:00:36 PM »

However, there have been a number of posts that state that these functions can be implemented in Mach3 using a macro.

Yes, but I've never seen one, and don't know how to do it.
I don't think you can actually jump to another point in the g-code, but I could be wrong. You can test for #100, but what you do after that would probably need to be done in the macro???

It would probably be something like this:

thickness = GetVar(100)
If thickness = 0 then
.....
