Input field for nozzel height of the extruder

JNB

Hey,
I'm often printing with changing nozzle diameters and therefore different nozzle with different heights (measured from the end of the screw to the tip, aka the height of the external part of the nozzle).

So it would be very helpful to have a input field in the settings to set the actual nozzle height for the extruders without touching the config each time.

Would be cool if someone could implement this.

Greetings

What setting in config.g are you changing when you change the nozzle?

Oh, sorry that was imprecise by me...

I'm using a BLTouch, so I have to readjust the offset of the sensor so the nozzel touches the bed when at Z0

An for the second extruder the Tool-offset

So you mean the Z probe Z Trigger Height - the Z parameter of G31?

@fcwilt correct, and (as I just edited ) the tool-offset of the second extruder

Which tool offsets are you setting?

Do you have a multi-tool printer?

I'm using a Tenlog Hands 2 which I modified with a Duet3 MB 6HC and a EB 3HC.

So it's a IDEX with two tools on one X-rail.

So you need to modify the Z offset setting of the tool using G10?

@jnb

Are the values you need to use always the same for a given type of new nozzle?

@fcwilt Well, I would say for normal quality nozzles the tolerances are trivial, so it could be seen as the same for the particular manufacturer and nozzle type

Well a fairly simple way would be to create a set of Macros with each macro containing the commands needed for a specific type/size of nozzle.

@fcwilt @JNB you could use BTN CMD for it i think
