Yishin, thank you for the answer. I am using MESA 5i23, 8i20, 7i49 (resolver card). I have 7i43-P (but without USB).
I succeeded installing Precise and compiled your LinuxCNC (wow, that was tough!), but I can't run it successfully. LinuxCNC starts, but throws this error while loading: Starting LinuxCNC... io started halcmd loadusr io started motmod: dlopen: /home/cnc/araisrobo/rtlib/motmod.so: cannot open shared object file: No such file or directory puma560_xyzabc.hal:5: /home/cnc/araisrobo/bin/rtapi_app exited without becoming ready puma560_xyzabc.hal:5: insmod failed, returned -1 Now I have even more questions: Isn't it possible to run some simulation without a hardware? Are these S velocity profiles realised in hardware only? If not - how to use them without this usb to 7i43 solution? Is it possible to use S velocity profile feature in RT linux? If yes - how? Would it be hard to implement other types of outputs from 7i43 to control servo drives, for example, 3pwmgen for direct bridge control for 3 phase permanent magnet synchronous motors (or BLDC)? BTW, there are things to consider / fix in your wiki page: 1. Descibe the base where to start from - a lucid distro, freshly installed from a CD or master branch or precise. If precise - how to make / get one - from generic ubuntu or from linuxcnc + upgrade.. 2. I got error running line "git clone https://github.com/araisrobo/linuxcnc.git";, telling me that directory linuxcnc already exists.. 3. Correct ./autgen.sh to ./autogen.sh 4. Explain how to run linuxcnc every time.. Or it is just dev-newbie - me?
