aluminium heater

[david-ganon 2]

hi, i installed all metal head on my um2

the heater made of aluminium (e3d) and i see that the temp go up and down all the time

i think that the brass hater is better because it stay hot, and the aluminium is cooled down quickly.

and that way it happens !

what do you think? how can i solve it? (i have 40w heater)

thanks

You need to set different pid values in your firmware. Just Google "auto pid ultimaker"

I may be easier to use the temperature tune from the @tinkergnome firmware. Have not tried this myself but it seem to be in again since version 16.01, will probably upgrade this weekend when I find the time..
