Hey Andypugh and PCW.
PCW
I will attach my Ini files tomorrow when I get back to the shed again. But
I think FF1 was equal to "1" But you guys really need to see my ini file
before we go any
further. But I know it wasn't 0.0005. I am pretty sure it was 1. and the
Min ferror I originally set up in Pncconf as .02 but then changed it to
0.20mm later on after I kept getting all these errors. When using the
setting up the tuning in Pncconf the table was actually back driving
itself. I would move the machine one direction and it would move and then
turning around and try to come most of the way back to its start position.
as you will see from the first video if you watch it.
Apart from that I will check these other values and see what I have and I
will post the Ini file here for you guys to check.
once again thanks for the help guys.
Regards
Andrew
Note: The pid_maxerror setting is in the hal file, not the ini file
removing all pid_maxerror settings from the hal file will
very likely resolve your issue. In addition, as mentioned
all P terms should be set to 1000
(assuming you are using a 1ms = 1000000 ns servo thread rate)
