Control printheads individually
-
I have 2 print heads, both are displayed in the console. However, if I activate one of them, the second one is automatically activated as well. How can I control the heads individually?

@axiom post your whole config

@axiom As @jay_s_uk said, we really need to see your entire config.g file. From the limited section you posted, it looks like you've created two tool heaters, H0 and H1. The screen shot shows two tools tool 0 and tool 1. But both tools appear to use Heater 1. So my best guess is that you've made a mistake in your tool definitions (M563) and mapped the same heater to both tools.
But that's just a guess with the limited information provided.

@axiom It is as I suspected. You have configured it such that both print heads (tools) use the same heater (H1). So if you change the temperature of one, the other will change also.
-
@deckingman How can I change that in the code?
-
@axiom additionally you have configured the heater1 with sensor0, and heater0 with sensor1!
Not sure if this is correct (depending of your installation and wiring)EDIT: To change the heater for your tool, change one of your tools to heater0 (H0) with the M563 command
e.g.; Tools M563 P0 D0 H0 F0 ; define tool 0 -
@cosmowave It works! Thanks, that was the solution!
