nope cv is on at 0.06, changing that value to 0.5 made no difference either

was the first thing i tried

i may look at a smoothstepper but Im a little nervous after hearing about kens G00 problems with his smoothstepper and his mill crawling and having to edit those codes out. He is on holiday now but I will hear from him when he gets back whether he got that resolved or not. I think the code itself may be very painfull .. my roland which can maintial 900mm/min on xyz is also crawling with the same code output to rml.. i think the lack of arcs to optimize movement is the issue here...

untill now the biggest files I have run have been at about the 12 to 20mb mark. that file was by far the largest.. the 20mb files gave grief if the toolpath display was on even for jsut index stuff, but much smaller files clocking in at only 4 to 7mb will also stall mach if the toolpath display window is on and the toolpath requires a rotation of A.

In answer to the last question, with this toolpath was the first time i got the complete failure where it actually cuts through my models. with other large paths until now its like the machine will stall then start again but in the right postion at least. so i get warning to run  down feedrate by hearing the jerky motion of the mill..

i was running 60 000 hz and 1548.******************x steps per. Vel = 1200mm/min and Acc = 350

no issues..  (other than the harmonic shudder at 800mm/min) 

i finally backed Mach all the way back to 24 000 hz and vel 780 and Acc 200 and cut this at 400mm/min to finish that job. anything more than 400 and it started skipping like mad..

thats like being in the dark ages....

oops extra info
that path will run fine on mach as long as i use really slow feed.. like 200mm/min through 400mm/min, as compared to my usual of running paths at 800 through 1200mm/min..

seems like the bigger the path the slower mach has to run..

the time it started turning A all by itself in code that never actually calls A at all it killed a really nice cutter.. didnt hurt the fixture too much tho...

here is a 43.5mb file.. typical output from the pathing wizard. uses 0.127 20' pyramid cutter and 0.02 stepover.

5 downloads only.. some new limit they using

path is half a ring side as illustration.

ver = 3.042.020

yeah i got 577mb usage from taskmanager

and answer to previous question. nope no arcs in this software.

to add to descrition of the issue.. its like the whole mill suddenly stops.. then starts again, but all the values are at the wrong places.. it carries on cutting but with incorrect Y and X.

I decided to write a path. wiull upload to rapidshare. I hope i can solve this as i really like the software, and its associated fixtures.

I have one gig in now , will push it up to 3gb but im thinking that its good money after bad, may as well just upgrade the pc to something faster...

will upload the nc file tommorow from work.. .. 48 mb wont fly from home at 15kb/s up..

It seems like mach should be able to handle it..

I will try more ram.. The software is DeskProto and its the strategy that's causing the huge file, spiral inwards at 0.02 stepover with 0.127 tip.

I am attempting to rewrite the wizard that generates the code to make it use a different strategy too.. hope it helps.
