HelloPeter, thank you for the proposal. There comes the next problem: In the *.hal file I defined for my machine (/home/..), I can only find values in these lines:
setp stepgen.0.steplen 1 step stepgen.0.stepspace 0 and likewise for the other two axes. Values 1 and 0 seem weird, if nanosec. are the unit. Changing them makes no difference in machine behaviour. Why can't I use halrun like described in the manual? Halrun accepts only files from /usr/realtime.../modules/emc where the machine I defined doesn't show up. Do I have to compile anything which the manual seems to suggest (p. 16 of the HAL Tutorial), and how can I 'invoke the emc-environment script to prepare your shell'? Halrun works, because I can follow the commands mentioned in the manual, but only with siggen and not my real machine.
