Kerf Bending with Grasshopper

"I would like to know how to control the digital kerfed panel with grasshopper (I tried to "bend" it with grasshopper, but the kerfs do not keep their shape, nor the panel). Any suggestion would be welcome! "

Single Line Font Curve Generator

A common part of fabrication is labeling the parts to make assembling easier, but typical TrueType fonts generally aren’t ideal for fabrication.  After looking into them a little, we discovered that the problem was because fonts need to be closed profiles and not just paths.  There are some pseudo single line fonts that can help minimize this problem, though there are often artifacts that may come through as missing or extra lines when Rhino drops part of the closed…

Mesh Split with Grasshopper

There are several commands in Rhino which have mesh splitting capability, but we’ve had limited success with them in the past.  This definition works for splitting a mesh with a set of a curves (lines, polylines, compound curves, etc.) by using a series of steps as described in the list below.  The sample file we’ve uploaded is set up to work in the XY plane, but can be quickly edited to work with other planes.

For more info, check out our post here: …

Hi Erick,

The current Firefly website is: http://fireflyexperiments.com/.  Unfortunately, the new service I'm using doesn't support a discussion board (at the moment).  I'm looking at implementing a 3rd party service... but haven't had the time to do it.  I would recommend posting any questions under the Firefly Group page on the Grasshopper site.  There are a decent amount of discussions running on that site and people can go and look for solutions to other problems as well.

As for your question about needing more juice... do you need more power? or more speed?  Steppers actually have more power the slower you run them... so if you're running it at full capacity then you might be trading off some torque power.  In addition, steppers are usually a little less powerful than servos (and other motors)... but you gain the ability to precisely control them for more than 180 (which is one limitation of servos).  Here's a good tutorial explaining some fundamentals of stepper motors: http://bildr.org/?s=stepper and here's a really good explanation of different types of motors and how they work: http://www.youtube.com/watch?v=5thxBgew7N0.  You may have to skip ahead a little bit to get to the motor control stuff.

HTH,

Andy
