Dave, right now users of LinuxCNC are mostly insulated from raw HAL editing by stepconf and pncconf. same wizards may be extended to write scripted components. With current declarative HAL and compilable comp it becomes too complicated. For example, ATC components mentioned yesterday are not generic enough to be used as is, and are not included in distribution. LinuxCNC is a free download, and fights against 100-200-500USD+ packages, and fails to get users. If our goal was to enable our own machines, we succeeded, time to go home. If we want to have best controller, we have work to do. EMC was designed with 40-100 Mhz processors in mind, now we have several cores with 2+GHz, please check you suspicions before you spread FUD. Scriptable components/HAL need not be top performance for 40m/min sub-micron machines, they need to be easy for hobbyists to enable their machine. For former one should find the time to optimize things, but we should not require the same from everyone. > Why do you think that adding a scripting language like Lua to the hal layer > would be desirable? Let me ask you back... Why AXIS GUI is written in Tcl/Tk/Python/C/C++ mix, it will be much faster if written with only C/C++, right?
