(Line may have to be unwrapped.) Jon, it depends on where you are looking at. In an RC system for model plane, if you look to the RF modulator input, you are right (first row of schema you posted). But if you look to each servo control wire (the original topic of this thread), then the information position is coded with the pulse width. Really that depends from the original Phil Kraft design and implementation (dated middle '60 if I remember well). The _recent_ RC servos are quite forgiving of the frequency of this pulse: the more advanced ones have a microcontroller inside in order to drive the electrical engine to a quite high PWM frequency and get lesser losses. That was not necessarily true in the past though, because the old RC servo circuits heavily depend on the pulses period of 20-30 ms in order to correctly drive the small engine inside. *am* - Andrea Montefusco iw0hdvhttp://www.montefusco.com tel: +393356992791 fax: +390623318709 - -- RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] and now for something completely different---visualizing EMC2 configurations
Hi Kent, all, another example of a software similar to what you are developing is GNU Radio Companion. http://www.joshknows.com/grc Albeit it is from a totally unrelated field (digital radio and DSP), this software too deals with blocks, wires and so on. Moreover it generates python code that implements the interconnections that the user draws, producing a fully functional Python program. It is written in Python with pygtk. http://gnuradio.org/redmine/projects/gnuradio/repository/revisions/96a20bb09dc6b07b3d2651645e579dff6c3f3a45/entry/grc/ Just my 0.02 EU. *am* - Andrea Montefusco iw0hdvhttp://www.montefusco.com tel: +393356992791 fax: +390623318709 - -- The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.

The question is - what would be the best way to do that? The client with a welding robot also expressed such an idea, but I talked them out of it.

I wondering if i am doing a useless job since someone else already did this or there's some other editor i am missing. Do you know of something as simple as xfig being able to write gcode? Do you think such an xfig patcg would be a useful contribution? For future versions i am e.g. thinking about using the line width of xfig to select tools and the layers of xfig for different z-values. Do you think this makes sense? If there something the color or line style could be mapped to? Great idea ! xfig allow to associate comment to single object or group of object (COMPUND). Its possible associate CNC info here.
