In case the Hostmot2 driver will only be limited by the stepgen limits.

I use a custom component, but I wrote that before I wrote Lincurve. Setting the values from G-code just seems horribly clunky. Setting the values of a lincurve from Python sounds like an afternoon of fiddling to end up with a better solution. Even with a custom component, I would skip the G-code idea. I assume you plan on sending angle and amplitude data on analogue outputs and clocking it through with a digital? It seems much easier to write a script that can parse spreadsheet data. (CSV, for example) even if you do use a custom component. You will need some sort of script anyway to create your crazy G-code. A custom component would cope better with wrap, possibly. Also it might be better with variable curve resolution. The only way to change the size of a lincurve would be to unloadrt it, then loadrt it at a differenct size. And then re-make the connections. Even for a custom comp would suggest starting with lincurve.comp. It's already nearly there. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
