Tempest Planning - Preliminary information and testing
poppabear:
Hey Art,
I have a cheezy shoptask, ( a semi wobbly machine), I am willing to try it on, let me ask a stupid question, do I just drop this EXE in the mach directory of my current Mach3, and replace the existing mach3.exe? Or do I need some other special thing to set it up.
The shoptask has a "Lathe" on it too, so is this testable with lathe, or just mill?

ART:
Should work on anything..

Just a quick question. Will it be possible to set up Tempest to follow a path exactly, stopping on sharp corners and maintaining velocity on tangent moves? So if using G41/G42 on an outside profile, you'd get CV while maintaining 100% accuracy? Thanks.
ART:
As yet,no. ITs like mach3 in that its either cv or it isnt.. Though that doesnt sound hard to do..

Repost.. Sorry, wrong file was attached to original..
Well, interesting results so far. I havent run many small segment files, but numbers so far look pretty good.
Im using a special version of Mach3 that has dual planner capability. One can select Tempest from the config/planner selection menu
and test various files in the two planners ( tempest and mach3's normal planner ) very easily.
Few notes,
.. config/select planner selects the current planner. If tempest is checked, your using tempest, if not, mach3's traditional planner.
Jerk and CV radius are the only other two entries. Jerk for most will be in the range of 1000 ( very shakey machine ) to 5000, very tight machine to perhaps
1,000,000 ( run close to mach3 levels of jerk allowance ).
CV is simply the maximum allowed radisl curve blend around corners..
Note:
1)DRO's for FRO are not working in this version.
2) do not use feedhold, its not yet written, you may only stop when using tempest.
3) No reverse or other fancy stuff, this is just a run time test of tempests motion
4) Do not transmit this program to anyone, its all just test code, its likely it will never be released into MAch3, but may appear in some other incarnation of controller.
this is simply my research and how its going.
I recommend trying a box a few inches on a side at various speeds, jerks and cv's to compare motion between the two planners.
Please report what you see in terms of motion, but again, dont expect all aspects of MAch3 to work.. ( though an amazing amount do..)
If you try very small segement code, let me know how it does..
Id prefer no open discussion of this planner, only those permitted on this topic, which I will add to as I wish someone to test it.
Thanks
Art
