Ok, thank You! I will take a look > I'm sure Peter or Andy will chime in and give you specifics Andy, could You, please, explain, how to integrate BLDC component in HAL file? I found these 2 pages: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BLDC http://www.linuxcnc.org/docview/devel/html/man/man9/bldc.9.html That second page lists all the possible input and output pins, but I do not really understand, how to load it? How do I specify in "loadrt" line that 3 bldc instances are needed? Or is the number of instances specified, when they are addf-ed to servo thread? Like this: addf bldc.0 servo-thread addf bldc.1 servo-thread What does that "personality" mean? I mean this line: loadrt bldc personality=P BTW, in 7i39 manual I noticed that in 50-pin connector it is supposed that Hall sensor feedback also is provided back to 7i43, but in the PIN file of firmware for 7i39 those particular pins on 50-pin connector are unused. Does it mean that the pins with Hall sensor feedback are treated as GPIO pins in 7i43 card and I have to wire them to bldc accordingly? How exactly should my config string look like? Motors have Hall sensor and incremental quadrature encoder. The thing is that I do not really understand the "rotor homing" part - should I include "i" in the string or no?
