After updating to beta 4.1, everything works fine. Thank you jay_s_uk!

@fcwilt Yes, compensation is on. I checked the M122 command, and also it is visible since the bed moves up / down when printing.

@dc42 said in Which tool is enabled after startup?:

A variable would only solve that if it was persistent between power cycles.

On my tool changer I avoid the need for additional wires and inputs on the main board by using a tool board for each tool, and connecting the dock sense switches to those.

If you have a spare analog input, you could use that for the effector docking sensor, and use different value resistors on each tool.

This is a fun way! How can you read the value of a resistor?

@Phaedrux The brake is permanent. That is, if there is no power on the solenoid, then the brake is on.

When power is applied, the brake is released. The power supply is 24 volts, the same as on the motherboard.

All I need to do is turn on the power before the Z motors turn on. Is there such a possibility?

If not then I use the M42 command inside homez.g

But if there is such a function, then I would like to use it.

@Phaedrux Thank you, I unfortunately did not find the answer to my question in the search.

I am planning to use a NEMA23 motor (with gear), this one

Here is a permanent brake that is released when power is applied to the solenoid.

The printer has 4 Z motors connected to the Duet 3 board, each to its own driver.

I want to connect the brake power to the bed heater on the Duet3 board.

The question is, is it possible to somehow turn on the power to the solenoid when the Z motors are activated?

@Phaedrux I searched the forum and found nothing. Can you provide a link?

I understand that I can insert brake release commands into the homing files. But maybe there are standard functions for the brake?

How can a permanent brake be connected?

I need to supply power to the solenoid before the steppers starts moving (Z motors).

Is it possible?

@luckyflyer can you tell how you turned off temperature controllers in S3D?

I think a space appeared when copying or the translator inserted it

Because value on gpin is "0" not null.

As I understand it, there are no restrictions and should work. Thanks, I'll check the wires and commands.

I would like to just understand these limitations in the firmware, or am I just doing something wrong?

It's just that the wires are already routed into the printer. It's not difficult for me to redo it, but maybe it should work?

Maybe someone knows?

Because I define

M950 J4 C "!^31.io1.in"; Input 4 for trigger

Then I look at the state of the input with the command

M409 K "sensors.gpIn [4]"

And I always get

"result": {
        "value": 0
    }

But if I define an input on the motherboard:

M950 J4 C"!^io6.in"

then when I close input to the ground I can see a change in state.

@Phaedrux Got it.
I also don't have any power outages. But I want to try to configure

Thanks a lot for your answers!
