I’m having two issues at the moment with Octoprint/Redeem:

  1. M303 (Autotune) doesn’t seem to ever end (turn off the heater) or print out PID values. Or maybe my own values are so far off that it can’t converge. Either way, this command never completes. I don’t even know how to cancel it other than to turn off the BBB.
  2. My Manga screen doesn’t seem to be reflecting the temp value changes. It does at first, but at some point it loses connection (or something) and the temp values shown become static (and incorrect).

Anyone else experiencing this or have thoughts?

  1. M303 is not ideal, I just closed an issue on that in the redeem respository tracker, but I guess that will have to be re-opened.
  2. Toggle loses the connection with Redeem some times. Not sure why, I think the client SockJS implementation is a bit off, I could not find a good sockJS client for Python, so it’s a hacked together version of something.

Tried M303 just now, worked fine for me.

@Elias_Bakken I think it’s a more general connection problem you’ve seen, because I noticed that sometimes Octoprint also kind of “hiccups” in its update status with redeem.

Nevermind, my “hiccup” issues were due to a bad wifi usb dongle…

Reproduced the M303 issue just now. I have a hotend with a very very high “momentum” (it continues to heat up and overshoot for quite a while after cutting the power to the heater). FWIW, it confuses the hell out of Marlin’s autotune too, i ended up having to reduce its power significantly, and even then, i had to manually tune it because the autotune results weren’t very good.

Manual PID tuning FTW. http://i.imgur.com/GYvQgbZ.png

@Ante_Vukorepa Out of curiosity, what hot end are you using and what were your final PID values?

I’m using a Dglass3D (D3D) auto-lift hotend. Semitec 104GT-2 thermistor. P = 0.05, I = 0.05, D = 10.00. It has a slight initial overshoot, but settles quickly, so i didn’t bother with further tweaking.
