Nan - voltage

Attached is my config.

I don't see it.

Another one to try:

installed.


first open.


okay, so i dont seem to be able to upload the screenshot/photo of the latest nan.

rest.assured. it looks identical to the others

Try with lowpass set to 0 in your connections.hal file

Phill, your a genius!(where can i send the beer), changed low pass to 0, 20/20 close/reopen no nan.
i mean can increase the group to 100 sample? but 20/20 is pretty good!

now, whats broken where?

That is a good question, since my last post I set my sim lowpass to 25 and have been running combinations of numbers but cannot get it to -nan
I guess I need to do some more testing. I might try it on my table and see if that makes a difference.

Does halcompile make a backup of the original plasmac.so? it should be in /usr/lib/linuxcnc/modules.

If not I will post an original comp so you can try it that way to make sure we are on the right track.

it does not, there are no obvious backups.

OK, here is an original.

Interesting.

the difference i see is "new"plasmac.comp == -0 for volts.


old plascmas.comp == 0 for volts


20/20 with old plasmac (just installed) no nan.

ill poke the low pass again to 25 n see if it Nan's on me


edit: second opening with lowpass 25 == Nan

Some time back a few guys said they didn't like the -0 so I made anything between 0 and -0.5 read as 0. It has to do with how floating numbers are displayed.
It is possible to fine tune the Offset so it doesn't go below 0.
