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!
