I'm having problems running high speed tool paths on older machines with not many look-ahead options. I get some slow downs and retract feed rate is not optimal it ignores what mastercam says. pfr # Feedrate W/O Negative Feedrates if fr$ > 0, fr$

hi, Thanks for the reply. My post look a little different # Axis Motion Definition section # -------------------------------------------------------------------------- pccdia2 # Cutter Compensation2 # tloffno$ = t$ if ccomp$ <> 4, tloffno$ pccdia # Cutter Compensation if ccomp$ <> 0, pccdia2 prapid$ # Linear line movement - at rapid feedrate n$, sgplane, sccomp, sgcode, x$, y$, z$, !fr$,e$ pzrapid$ # Linear movement in Z axis only - at rapid feedrate n$, sccomp, sgcode, z$,e$ plin$ # Linear line movement - at feedrate n$, sccomp, pccdia, sgcode, x$, y$, z$, pfr, pcan,e$ pz$ # Linear movement in Z axis only - at feedrate n$, sgcode, z$, pfr,e$ pcir$ # Circular interpolation if plane$ = 2, n$, sgplane, sccomp, *sgcode2, x$, y$, z$, pijk, pfr, pcan,e$ else, n$, sgplane, sccomp, *sgcode, x$, y$, z$, pijk, pfr, pcan,e$

Hi Is there a way to edit the post processor and post the feed rate on every line? Similar to what "Highfeed" does. I'm using mastercam X6 and a post processor provided by hurco. Thanks

It acutally runs a little faster with the filtering on.

I think i have the latest version of Ultimax. Yes the machine can be upgraded to Winmax but thats out of the question, too expensive and i have more than one.

Hi I'm using mastercam X5 and programming a lot of high speed toolpaths. Most of these are dynamic area and dynamic core. Running these in the VMX42 based on winmax it runs smooth and fast using SFQ of 50 (1-100) any higher and the machine deaccelerates on arcs and when backing off from the cut to make another cut. But Im happy at 50 SFQ. The problem is running the same nc file on another VMX42 this one based on Ultimax everything just slows down. The actual feedrate is there but it slows down so much on arcs, back retract feed rate and rapiding. The machines ignores the performance parameters, they have no effect unlike the Winmax machine. There is really nothing I can do at the machine. Is there something i'm missing in mastercam settings? I'm using Arc filter / Tolerance 2:1. I'm feeding at 250ipm, 10000rpms, back retract at 500imp. What about a G-code? I have been reading alot about G5 or G05.X which i dont use, is the really what i need? and how do i set that in mastercam?
