In the meantime and if it's any help, there are others using AutoCAD together with AutoLISP to create the necessary Gcode for Mach3.
The basic details can be found here;    http://www.woodweb.com/knowledge_base/How_to_Generate_CNC_Code_Using_AutoCAD_and.html

Tweakie.

If you want to create g-code from within AutoCAD, try  my VBA macro.

Much easier then messing around with Autolisp.

No, the steps/unit is in the motor tuning.

Right next to the other ones.

I don't use a mill, so I'm not sure which way the machine is supposed to home to.
However.
You have your machine set to home in the positive direction, in order to move towards your switches. This is why you're having trouble with softlimits. Anfter the machine homes, it only moves in the negative direction.
The way you have it setup now, your softlimits would need to be Max = 0, and min = -100.
I think that you may have the machine setup backwards. Either that, or your home switches are at the wrong end.

IF everything isd correct, and your home switches are at the positive end of travel, then set a Home Offset of 100 for the X and Y, then your softlimits should work. (although your max is probably more than 100? Set the Home Offset to the maximum travel distance, and softlimits to match)

Those numbers are very wrong for a machine set up in inches, unless it's a very expensive, very high performance machine. Those are numbers you usually see for a machine set up in mm's. Since it's a chinese machine, that seems about right.
What are your steps/unit set to?

As for the post processor, you should be using a Mach3 post processor.

Your X and Y axis are homing to the positive end of travel. Check the Home Negative boxes in Config>Homing Limits for the X and Y axis.

You need to look at it as the direction the tool is traveling, and not the direction the table is moving.

Here's a post from the guy who designed it explaining why it died, 5 years ago.

You need to make sure your native units are correct, and y our steps/unit are set correctly.
One or the other, or both are wrong.

Go to general config, and check "Stop CV on Angles>", and set it to 89. Then turn Constant Velocity mode back on.
