Input field for nozzel height of the extruder

@jnb said in Input field for nozzel height of the extruder:

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

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
