THANKS MANY THANKS I WILL TRY IT.!!!!!!!!!!!!

Hello guys,

a friend of mine has bought a complete mill-pc-software-bundle for doing his rc-car-things. Now i tried to help him getting started with all that, but there is Artcam included (i'm a SheetCAMer)

We tried to make an engraving-operation for a door-sign (that looks really cool with that sharped corners btw), but when we started milling, the whole machine does very short, linear, jerking moves and was trembling all the time somehow. It DOES cut what it is supposed to be, but you can see that jitter of the machine on the edges of the path and i don't think it is good for the cutter, mill and spindle, too.

I first thought there is a problem with the Mach3-CV-Settings, but when i try a piece of GCode from (my) Sheetcam, everything is moving nice and smooth, also short moves.

When looking into the GCode i saw only very short linear moves, not even one single Arc or Circle.
Now i read here about Postprocessors that does Arcs and Circles instead of short lines, when possible. So we tried some included PPs like the Axyz-Arc-mm-PP and the G-Code-Arcs-PP, but there is absolutely NO Arc or circle in the resulting Code?

Can anyone send him the Mach3-Arc-PP and tell me via PM?
His Email is ordering111 at arcor.de

Maybe this PP can do Arcs, resulting in a smoother movement?

Thank you very much!

Greetz,

Marc

Hello Spartan,

Its been awhile ive played Artcam, but what I can tip you of is:

You can try using a Fanuc Post Processor because Fanuc and Mach3 happens to use the same G-Code language. Try searching for Fanuc Post Processor in the ArtCAM post processor folder. If you have found a fanuc pp, use Notepad to open the processor file, and look whether it has commands for G02 and G03. These 2 G-Code Actions are Arc Movement Actions for Mach3.

PS: I've no more access to ArtCam so this is the best I can help you with.


Good luck!

Also been a while since I've really dug into ArtCAM, and am a little rusty. However, this does not sound like a post issue. Sounds more like the toolpath is set so that ArtCAM is trying to raster the feature. Possibly you used an image in ArtCAM to create the toolpath instead of a vector? An engraving toolpath should smoothly follow the vectors of the feature. Depending on the feature you may still get many line segments instead of arcs, but the motion will be smooth, not constantly reversing direction. If you could post the ArtCAM file I might be able to help you out, I still have an old copy on my computer.

Hey guys.

No, it was a very smooth vector-contour, consisting of many arcs and created with my DXF-Tool.
I don't have the file here, i will write him to send me a copy asap

Thank you and regards,

Marc

It seems that this post processor has a code that it will go to the home position before running the program.
When i set the fixture offset, i will start from the position it is, and not from the homing position.. Is there a way for that?
I will save some time

Did you use a program to edit the PP ?

Maby it goes to "Home position" because i set the "Home position" for changing tool...
Maby i can set the "tool change", there the machine IS ?
