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

Yes, it's weird. But I'm just a little tired of figuring out where the problem is.

So I connected the relay:

M950 P1 C"e1heat" ; Power disconnect relay for BLtouch
M42 P1 S1 ; And turn it on right now

And after the start of printing, I inserted the command M42 P1 S0

And that's it. Working. I sleep well

Maybe this will help someone. But of course it's better to use Duet 3 toolboard 1LC for the extruder and connect BLtouch there.

@dc42 What if the solution is to my question?

@dc42 Thank you! We are really looking forward to this feature.

@Phaedrux Thank you! I really want to try it! Very necessary.

@moth4017 No, I need to interrupt the current movement. Without losing position.

Hello everybody,

Is there a GCode command or some way to stop the current movement? I need to stop movement by pressing a physical button.

So to have a smooth stop without losing the current position?

@dc42 Any news on this issue? I decided not to make a new topic so as not to create duplicates.

@dc42 Is there any progress on this issue?

There is another idea - you can write a macro in which the submission of a micro movement command will be looped. In this cycle we can check the state of the pin and exit by pressing a button.

I need this to connect a weight sensor in a photopolymer printer.

@Phaedrux That's exactly right. I think. And there are a lot of wires around.

@droftarts

Duet 3 I used on another machine and there are no problems. Works great!

In this machine, unfortunately, there is a Maestro board. So yes, tomorrow I will solder the relay, thanks for confirming my idea I will break the + 5V supply that goes to the sensor.
