Hi Kent,
Halscope shows that there is no signal on the parport pin, but that
zstep (and stepgen) are producing output.
This seems to mean that my hal is wrong.
There have been some syntactical changes between my somewhat dated
original and the newest EMC2, maybe I have translated wrongly.
I have read the manuals and tried to see what is wrong, but cannot :-(
Maybe some kind soul could cast a quick eye over the following and say
"What kind of idiot wrote this then?" - or similar maybe with a pointer
to what is wrong.
Thanks,
Bob
