I'll go disconnect the 5 volts I made up to feed it there and double check.
What I wound up doing was unplugging the usb cable, and feeding my 5.15 volts into those connections, and it doesn't seem that the BoB cares where it gets its 5 volts, and my supply can do 1.5 amps till the transformer melts down. But now I have a repeat of the same problem the older box gave me, and which was usually solved by a power down reboot. I go to run "linuxcnc -l" and get an instant bailout, its version of insmod cannot find the first or 2nd module named in the loadrt section of the hal file, the module in this case being hm2_pci. My assumption, since there have been unumerous updates installed, something font related between shutting LCNC down 3 hours ago, and attempting to rerun it just now. I can "locate" hm2_pci.ko, I can ls -l it once I know where it lives, but linuxcnc can't find it. And I just did a powerdown reboot. I just checked the "env" for both "lathe" and "shop"(the toy mill) and nothing in the environment gives a hint of a path to /usr/realtime(-etc/etc/etc) However, cat *.txt in the ~ dir shows: ======================= gene@GO704:~$ cat *.txt 4332 PID TTY STAT TIME COMMAND Stopping realtime threads Unloading hal components RUN_IN_PLACE=no LINUXCNC_DIR= LINUXCNC_BIN_DIR=/usr/bin LINUXCNC_TCL_DIR=/usr/lib/tcltk/linuxcnc LINUXCNC_SCRIPT_DIR= LINUXCNC_RTLIB_DIR=/usr/realtime-3.4-9-rtai-686-pae/modules/linuxcnc LINUXCNC_CONFIG_DIR= LINUXCNC_LANG_DIR=/usr/share/linuxcnc/tcl/msgs INIVAR=inivar HALCMD=halcmd LINUXCNC_EMCSH=/usr/bin/wish8.5 Using previous inifile: /home/gene/linuxcnc/configs/GO704fast/GO704fast.ini INIFILE=/home/gene/linuxcnc/configs/GO704fast/GO704fast.ini PARAMETER_FILE=linuxcnc.var TASK=milltask HALUI=halui DISPLAY=axis Starting LinuxCNC server program: linuxcncsvr Loading Real Time OS, RTAPI, and HAL_LIB modules Starting LinuxCNC IO program: io Starting HAL User Interface program: halui Killing task linuxcncsvr, PID=4332 Removing HAL_LIB, RTAPI, and Real Time OS modules Removing NML shared memory segments ================ But an ls of the path shown in LINUXCNC_RTLIB_DIR above shows all the modules present and accounted for. Where is that path setup for use by linuxcnc to find its realtime modules?
