Tempest Trajectory Planner / Re: Tempest Planning - Preliminary information and testing

I think you could recover some of the lost time Tempest "costs" in the following way.   Mach3 presently does the acceleration setup from a standing start.   I believe you can, for most machines, achieve greater acceleration from a moving start due to higher static than dynamic friction.  Since Tempest will limit jerk, the starting acceleration will be smaller than the peak acceleration.   Allowing for margin in both cases, my guess is that a machine set up to take advantage of this fact could make a substantial improvement in Tempest mode over standard setup in standard mode.

  I have a couple of questions about Tempest.  I have read the thread up to this point and I am not fully clear on the reasons for Tempest.   As a physicist, I do understand jerk and snap.  I also appreciate the fact that what you are doing will make the Mach3 machines run "more smoothly".   But what are the specific ends you are trying to achieve?   Better looking results on the workpiece? Less wear on the machine?  More axes? Less error in the cut path?  I ask because it is helpful to fully understand the objectives when testing.   It will help me select test parts from parts I am making.
 My second question relates to processors.  Is this module designed to take advantage of multiple processors?   My desktop now has 4 cpu's (8 if you count hyperthreads).   More will come in the future.

Brian-
   No luck with replys - any suggestions?

   Thanks.   How can I get Steve or Kenny to respond to this?

General Mach Discussion / Status of Galil Integration w/Mach

« on: February 14, 2009, 04:49:28 PM »

Maybe this is the wrong forum, but I am interested in using Galil servo drives.   What is the official status of the Galil drivers/plugins?   Is anyone using dual encoder inputs (servo) on a Galil/Mach3 setup?  What do you give up, if anything, by going with Galil hardware?  Tnx in advance.
