Hi all,
Is there a way to output the temperature to a log file? I want to play with the PID gains, since it seems like the control is not very good when changing temperatures during the print. Also, it would be nice to have the temperature profile for when the prints are very good in sections, or very bad in sections.
Have a great day,
Jim
Re: Temperature output log
Hey Jim,
There's no way to output the temperature data to a file, but if you're using the Marlin firmware you might have good luck with the M303 command. It runs a PID autotune and will tell you the best P, I, and D values for your setup. It's usually best to do this from a cold nozzle. While it might not be perfect, it definitely helps get you close!

Clayton,
I would like to file a formal request for this capability - or informal, or whatever it takes. Not just from the standpoint of PID work, but also to sort out why some levels of a print are just nicer than others. I think it is related to temperatures, but I can't prove it.
I have tried the M303 command, but it doesn't converge for me. I thought it was because I was starting from a cold nozzle so I tried various starting points with no luck. I have also tried another calibration that somebody on the makergear forum had done, but I was still getting significant overshoots. I guess I will either have to get used to the control I have, or find another way to get what I want.
Thanks anyway,
Jim
