While thats always a possibility, but its a test reading I did multiple
times for both conditions, and until I added the
setp output-invert true,
which made it backwards, so I setp'd it false and it works as expected.
ATM its the middle of the night and I'm trying to see if I have all 4
stepgens ready to hook up later today, and I find I cannot see the
actual steps with a halscope any place. So I'll have to scope probe the
7i76 stepgen pulse outputs. Is this correct? Or is there a way to see
them on a halscope pin when there is no base thread? I can't find an
output that shows them, Probably too short for halscope running on
srevo-thread to see. I can see the dir changes at the corresponding
gpio.in, so I assume they are working. I'll try to get that all hooked
up today, leaving the home switches and encoder to sort tomorrow. And
that should get that mill 100% usable again. Leaving me plotting how to
make a tool changer for it. And searching for an endoscope camera that
actually works.
On another front, I have the alignment kit working well on the 6040
already. Theoretically, just copying that code to this machine should
handle that. easy-peasy on the 6040 as the workpiece is usually mounted
on a spoil board and therefore insulated, so it could be made to use a
G38.2 to detect the angular error. Aligning the machine to the workpiece
rather than the other way around.
Thanks Peter.
