controlling two heaters in one extruder
-
Hi all,
I was trying to control two heaters mounted on one extruder.
I need their temperature to be different from each other (e.g. the first heater 120 degrees and the second heater 220 degrees).
I have also mounted a fan to cool the first heater in case its temperature was raised above the set value.
What is the best way to configure this setup using the firmware configuration tool?? -
To configure the temperatures for two or more heaters on a single tool, use the G10 command to set the temperatures. For example:
M563 P0 H1:2 D0 ; tool 0 uses heaters 1 and 2
...
G10 P0 S120:220 ; set heater 1 to 120C and heater 2 to 220C -
@dc42 many thanks for your reply, I will try it.
and regard using the cooling fan to cool the heater if it overheated
I tried to use this command
M106 P0 S1 I0 F500 H2 T120However, I have noticed that once I give the printer a job to print it stops executing this command. should I add any commands in the slic3r?
Thanks

When you configure a fan to be thermostatically controlled like that, you can't control the fan manually unless you first disable thermostatic control.

@dc42 can you please advise me what command is used to trigger the fan based on the temperature of the heater?

The command you gave before:
M106 P0 S1 I0 F500 H2 T120
will turn fan 0 on when heater 2 temperature is 120C or more.
Note, Fan 0 output is normally used for the print cooling fan. I suggest you use fan 1 or 2 fr the hot end cooling fan.
