Hotend temp question
-
In my temp chart the hotend is displayed by a wavy line which I presume the Duet2 is turning the hotend on/off continuely
I have tuned the temp for the hotend and used the results it gave me.I thought I saw a post the other day about this, but cannot find it.
My other printer is a continuous flat line for temp on the hotend.
Thanks.

@paulhew have you tuned the hotend PID loop using M303?
See: https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control
-
Yes I did use the M303 command, I will however try again.
-
If you don't have a silicone sock around the heater block on your hotend I would suggest doing your heater tuning with the part cooling fan turned on and the nozzle fairly close to the bed.
-
Can you show a picture of the graph? What kind of wavy is it?
-
After calibration... You have saved results? Think M500...
What post calibration message in console?
-
After re doing the PID tuning, it came back with different parameters than I had the first time.
I manually change the values in my config.g as opposed to using the shortcut.
I now get a consistent temp.@Phaedrux I cannot show you now, now that I have fixed it.
