Thank you Andy, I completely overlooked the setting... Everything is working now. Thanks again for bearing with me.

Hello Andy,

First of all, thank you for your great work.

I am trying to control 30 servos with Arduino Mega 2560 but it seems the servos only twitch as I slide through 0-180 to mega write, and I tried to connect only one servo to different digital pins in several times, the results are the same.

I tested with Uno and all 9 servos worked under the same set up, so I imagined there might be something wrong with the firmatta, and I came across this post in 2011:  http://fireflylabs.squarespace.com/discussions/post/1540044

the Firefly version I'm using is 1.0.0.70 64 bit, does it cover for the "buffer size" and "baud width" issues that you mentioned on the post? 

I am using Rhino 5.0 and the grasshopper version is april-04 2014 build 0.9.0075. the Arduino IDE version is 1.6.5

Thank you for your time.

Hello ,

Andy I sent you a friends request. I am emanuel From the workshop at

TEXFAB.  I am having a issue with the steppers and was wondering if you could take a look at the Grasshopper build that i have used from the library samples.

Thank You

Manny Ferro

Thanks Andy. That cleared up a lot and reinforces what David explained. Had the same thought about handling the high frequency data on Arduino and sending data much less frequency to Grasshopper. Sounds like a challenge that will take some time to figure out. 

Hey Andy. Have much enjoyed your gcode definitions in the past and have started using firefly, another great tool. I am trying to do something that sounds like it may have a technical roadblock. I want to read pulse output from an arduino that is running the gcode interpreter GRBL. I use grbl with my diy cnc but I am trying to cobble together a simulator for testing and understanding the firmware and gcode programs I use. The arduino pumps out pulses that are only 5-50 microseconds wide. I think I can set them as big as 255 microseconds wide. I can read the output at 1ms intervals using firefly but obviously drop a lot of information. Do you think there is a way to successfully read those pulses in through firefly? 

Hey Andy,

many thanks for your great plug-in.

I am trying to start using Kinect in Grasshopper and I am wondering if you can provide me with some tutorials/hints for beginners?

Many Thanks

Hi Andy,

i've hooked up a dc motor with an h bridge circuit and i have been able to control the rotation and speed so far through Arduino code. Now i wanted to do the same through Firefly, but it keeps working with the Arduino sketch ignoring the current values i am sending through Firefly, shouldn't the Arduino sketch be overwritten? However that was not the case with servos..

Should i reset the Arduino?

Thank you

Andy,

FYI, I just hooked up a different type of stepper motor (http://robotics.reefat.com/wp-content/uploads/2008/08/PF35T-48L4.pdf) and the speed is much better.  This must be a hardware issue I'll have to look at.  Sorry for the trouble.
