Hi, after we did some on-line control experiments using a LinuxCNC controlled 3+1axis router and a Kuka robot I wonder if I would be possible to get rid of the Kuka controller (hard- and software, servo amps, etc.) and replace it with a LinuxCNC based solution. The main problem with the existing Kuka hardware is, that (without buying expensive upgrades) I can't gain control on the tool path interpolation, but only stream coordinates ever 100ms or so. Using LinuxCNC, I think, it should be possible to feed real time input either to the main control loop (10-30ms) or directly to the servo control loop (0.1-1ms), right?
The Kuka controller would give me access to the main control loop with a 12.5 ms cycle time, at best. There is a faster servo loop, but this one is handled by a dedicated FPGA based hardware solution. So I guess LinuxCNC could give me more controll at less cost. What do you think? cu Flo PS: In case you're interested, here you can find some of the mentioned experiments: http://vimeo.com/user13525567/videos http://vimeo.com/56125747 http://vimeo.com/56130642 ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
