2 extruders and I need to lift my second

[Danny Defelici]

I'm using 2 extruders and I need to lift my second extruder when it's not printing. So I'm trying to use.
M571
How do I address the second extruder using this command

[Phaedrux]

Well you wouldn't really address the extruder, you would address whatever mechanism is going to move the extruder in and out of the way.

Can you give some more detail about what you have in place?

I'm looking to engage a air solenoid when extruder T0 finishes and extruder T1 starts to print. I have to push down T1 well it's printing, and springs bring it back up.

Here is what I'm trying but nothing seems to happen. The solenoid actually works though during startup, when I power up the machine.

M106 P0 I-1
M571 P"FAN0" S1

I suggest you configure a GPOut pin to control the solenoid (M950 with P parameter), then you can use M42 commands to energise and release the solenoid. You can use these M42 commands in the tool change files.

could you give me an example. We can use the expansion header above E6.

I need a trigger signal every time extruder T1 becomes engaged.
Just to be clear I have 2 extruders, T0 and T1.

I have to push down T1 with a solenoid every time it needs to be used.thanks
