Any way to let Mach3 know that it has to take into account the tool diameter when machining a concave or convex shape? See drawing attached.
G41 and G42 work left and right, I need to brake the tool advance or accelerate it depending if it is climbing or going down.

No, you'll need some 3D CAM software for that.

[cocodet]

does anyone knows such a software?

[ger21]

How much do you want to spend? Are you surfacing the whole part, or just cutting a slot with that shape?

[cocodet]

I want to spend zero or close to it. It is only for a hobby.

Freemill at www.cncportal.com What about the second question I asked?

[cocodet]

It is a wide surface. I will write a VB software for my application. Thanks for your help

[ger21]

If you have an .stl model, Freemill will write the code for you.

Is this 2D or 3D and is the cutter a end mill with a ball nose?

Take an stl file - through the demo version of STLWORK2 - You can account for the tool diameter (endmil/ball etc - you specify) and even cut in waterline -- or slab if you like.

No VB programming required - you gotta like that

But if you want the purchased version I recall its about 125 bucks- so not free - but affordable. It will do a demo cut run for you too - let you QC the code.
Not associated - Just like it. [IMSERV - they advertise on the 'zone]
