l equations that describe his attractor in a chaotic behavior when rho > 24.7. All the values of X =sigma(Y-X) *dt never repeat themselves through each moment in time making their distribution totaly random, we can see this at the end of the video with the linear graph. The beautiful thing is that even though the values of X are randomly distribuited over time, the result is a beautiful ordered shape, this in essence is the principal of chaotic systems. Or as James Gleick would say " chaotic systems embed hidden ordering principles"
X =sigma(Y-X)
Y= -X*Z+rho*X-Y
Z = X*Y-betta*Z
X = dx/dt -------> change of X over time
Y = dy/dt -------> change of Y over time
Z= dz/dt -------> change of z over time
rho = 28
betta = 3/8
sigma = 10

that it can send out. Best to have a dedicated control for this. Mach 3 is pretty good for what it is, but there is a reason that nice commercial machines end up with their own controllers that are RISC based. If you are using Mach3 currently, and you are interested in the advantages of having a DSP based control, which includes the ability to have a true closed loop system (yes even on a stepper based system), then you should check out Dynomotion Kflop (www.dynomotion.com). Come to think of it, your idea of having Grasshopper be a "control" of sorts could be easily accomplished with a Kflop board, as you are free to do what you like with it so long as you understand C and/or .net. …

ld be by no means a general benchmark of all arrays and lists, but it would give an idea of where List<T> and where T[] might be more appropriate.
Here is how you could set this up: on my PC, with 1'000'000 arrays/lists constructions and 50 inner loops on each, "arrays vs. list" has about 1:2 speed relationship, and "array vs. unknown length list" 1:9. You can test on your system and change the tests, too. If you do, remember to build in release mode and "Run without debugging".

... and on a PC without anything attached to the serial port. When you open the port, start the read component and its timer, do you then get a stream of <empty> values in the log output? (hmmm... I suppose that's only reasonable - but still, you are also seeing this?)
I suppose that, because of the mutually exclusive behavior of both the spider and grasshopper (i.e. only one at a time can access the COM port), we can deduce that we are listening on the correct port.
Am I listening on the correct pin (if such a notion makes sense at all)? If I look back to the spider software, I see that 9 channels are listed and that it's only the measured value on channel 0 that changes when I press the load cell. Channels 1, 2, and 3 report OVERFLOW; 4, 5, 6, and 7 are pretty much constant at 0.000 to 0.005 V; and channel 8 says FFFF. I do not know how things like that work so I do not know if they reflect reading from the 9 pins on the D-sub 9 connector.
As for your BTW question: no, I don't need to record all of the sensor values. I suppose that the Out value on the Read component will always reflect the most current value and that's all that I need to get on with life. In the end, the idea is that we have 4 load cells in the 4 corners of a plate onto which a vertical pipe is fixed. Loads are then put on the top end of the pipe and we'll have to visualize both direction and magnitude of the bending moment that is calculated from the compression - tension readings from the load cells... We've done this on a scaled model and streamed load cell information into MatLab. Now we'll have to use a different datalogger and I was hoping to be able to do the post processing in Rhino.

all the plugins but when I try to open my folder I always have an error which is the following:
Object: KangarooA (level 1)
{
Exception has been thrown by the target of an invocation.

Does anyone have any idea why I am having this problem.. thank you…
urface,like
surface0 had 41 floors
surface1 had 28 floors
surface2 had 21 floors
I tried to change the data matching of the <move> component but still can't make the result that I want.
beside that, are there any component can let the overlay boxes can separate like this:
i make it manually by bake and move and bake and move..............
please forgive my broken english.
thanks

are not copy with the number that belong to each other, like:
untrimmed surface0 should be 41 pieces
untrimmed surface1 should be 28 pieces
untrimmed surface1 should be 21 pieces
it result like this
exclude the 1st and 2nd pieces,the others all is untrimmed surface 1
and the attachments is the result that i want, I done it one by one.…
pen Brep"; I didn't know it worked on flat surfaces. And I think it's only fair to include in your benchmark the considerable time 'SUnion' takes in this example: 21.9 seconds for 121 rings and likely much more with 400 or 1,000+ rings.
Then I noticed the pattern doesn't match. Checked the circles and they are the same. The distance between them, however, is different: 7 instead of 6. When I change that value to 6, the Python fails badly. All the holes and gaps are gone, which destroys the pattern:
I can't do the "two phase" approach on an 11 X 11 grid, but I can do 6 X 6 and 2 X 2 to get a 12 X 12 grid (40 'SUnion' operations) in 28 seconds total. That beats your benchmark of ~37 seconds for an 11 X 11 grid, if you include the 'SUnion' in your code.
