Re: [Emc-users] BLDC - not smooth rotation with hostmot2 and 3-phase bridge

2013-06-18 Thread propcoder
I would not expect very smooth operation in 'D' or step motor mode (no encoder feedback/PID), especially with IGBTs and their long switching times that neccessitate a large dead zone. Do you have the dead zone time set properly? I think the default is 5 Usec which is (deliberately) huge.

You don't have to run Rockhopper all the time (which is the source of my problem). You can just launch it from the command line and connect to it with a web browser when you want to do a hal graph. If you launch Rockhopper after Linuxcnc is running you will never see the error I have.
