10:38 AM skunkworks: pcw_mesa: you around?
10:43 AM skunkworks: hm2 read.tmax was 1.1ms
10:44 AM skunkworks: my tuning params are
10:46 AM skunkworks: https://pastebin.com/rm8nXRPV for all axis
10:50 AM skunkworks: and I don't have the velocity dirivitive of the pid hooked up
11:07 AM skunkworks: normal following error is less than .00001
11:07 AM skunkworks: or so
11:22 AM skunkworks: I raised the following error to see if I can catch it (with out it stopping)
11:24 AM skunkworks: (originally min following error was .001
11:24 AM skunkworks: now it is .10
11:25 AM skunkworks: .010 I mean
11:25 AM skunkworks: and of course it hasn't tripped
11:25 AM skunkworks: when you are only looking at one direction of one axis... (positive error of joint 0)
11:35 AM skunkworks: ok - the scope started triggering and I kept hearing thuming. (like it was getting worse) then there was an actual following error and I also got a hm2/hm2_7i92.0: error finishing read! iter=516470
11:36 AM skunkworks: could this be a noise issue?
11:37 AM skunkworks: no servo thread overruns..
11:37 AM skunkworks: or read overruns
11:39 AM skunkworks: or read overruns
11:41 AM skunkworks: I did have the dpll timer set to -500.. I changed now to -1200
12:02 PM skunkworks: following error seems to peak at about .0002" normally...
12:14 PM skunkworks: seems to corispond with the readtime spiking..
12:20 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20191013_120802.jpg
12:21 PM skunkworks: seems to average around .0002ms and peaks at 1.2ms...
01:38 PM skunkworks: *.2ms
02:19 PM skunkworks: Hmm - the read time always peaks at 1694409 clocks which is around 1.1ms
02:19 PM skunkworks: that seems to be when the following error rises
02:25 PM skunkworks: ok - it seems like when the read time is above 1ms-ish for more than 1 period..
02:25 PM skunkworks: is there a hard coded limit of how long the read is allowed?
02:26 PM skunkworks: is there a hard coded limit of how long the read is allowed?
02:26 PM skunkworks: heh - too many keyboards
02:26 PM skunkworks: heh - too many keyboards
02:36 PM skunkworks: yes - I don't see the read time much over 1.1ms and if it is only 1 period the following error is small. If the the read time is a the 1.1ms mark for more than 1 period - the following error climbs
02:40 PM skunkworks: I think I need to run this on a real pc and see if I have the same issue
03:45 PM Tom_itx is now known as Tom_L
