[Emc-developers] how does that 5axiskins bridgemill switch kins in master work?

It's amazing. linuxcnc masters/magicians often do really nice things that are far beyond my realm of understanding. I just built a rip from master and had a look at the vismach 5axiskins bridgemill sim. In axis on the right side pops up a panel to switch Kins types, that I'm really interested

Thanks for the hint, Rod. If I get that right, [TRAJ] COORDINATES is the only thing that does the job of assigning axis to joints. No other axis-name/joint-number relation the W-joint needs to be declared in .ini file, but because there is no "Motor" behind, it doesn't need configuration

At the moment I'm on Reinhard's page thinking that TP has to be done i a separate module rather than going to happen in motion. But maybe I doesn't see the full picture. What are the key factors why TP actually happens in motion? Sure, there are some occasions where trajectory needs to be

If you're looking to hook up a bus system to your computer, you probably should go toward CAN. Sure, there are a lot of old VFD's around, still using Modbus. I've nothing against modbus, but it is an old hat on it's downhill path, On the other hand, integrating CAN in linux is not to hard.
