Hi Graham:

  Thx for the test file. The arc interpolation was wrong on a couple fronts. I suspect some helical trouble when joining helix's , but this version fixes the general arc trouble you had.

I am probably testing the wrong sort of code.  Short segment 3D vee carving. About 1200 lines.

Ordinary Mach, it runs in 13 seconds.

Tempest planner, the best I can get is 27 seconds and that is with jerk set to 1,000,000

Down around 20,000 it is snail pace.

S'pose this is not much interest to you.  What sort of code is best to test?

Greg:

 Actually, any type of code will do. Small segement 3d will be the hardest on it in reality. Im just fixing arcs and helix's, probably fix by tommorrow. In the meantime 3d code isnt bad,Id stay away from code with arcs in it till then. Raise the Jerk limit to 5000000 and see if it approaches mach3's speed. IF it runs OK, but a bit slower than Mach Id be happy.. the blending woudl still be effective. But for small segement 3d code, there isnt much way to remove jerk without slowing it down by jerk limitation. I guess its god's way of saying "3D code is jerky..no matter what."

thx

Pushed it up to 5,000,000 and got it down to 24 seconds.

So I also pushed the acceleration up from 1200 to 2000 and now it is down to 20 seconds

Art,

Just tried it with my Emco F1. I put a round bar on the table to "monitor" the jerk. Played with the jerk number from 1 up to 100,000 and was jogging the table from side to side. There was no difference at all that I could tell of. Looked the same with any jerk value, as well as with the normal Mach3 mode.

I guess this information doesn't help you much.

  Select Config/Select planner to turn it on.. Jogging isnt differenet..only GCode...

Hi Art
Attach is a file you could test which I get weird stuff happing try it see if it runs alrihkt on your machine if I do circles or arch the Z axis moves up and down when runing G code    Thank you

Hi:

>>So I also pushed the acceleration up from 1200 to 2000 and now it is down to 20 seconds

   It goes to show that the file , when proper physical limits are enforced on the blends has a 20 second time minimum. Mach3 does push the envelope quite a bit so Id expect longer file times on many file types.

Testing continues, good results so far other than the small bugs showing up.. :)

Art,

I did select it, but I didn't realize that jogging wasn't different. I thought that the acceleration profile was changed ??? If so there should have been difference in the jogging as well...

Hi Guys:

  Sorry about that, it was indeed doing circles on arcs. Fixed in this version.
