Filament based Z Offset settings  

RE: Filament based Z Offset settings

Why not use the sheet profile in the printer? One for PLA, one for PETG, even if it’s the same physical sheet.

Yes, at the same time you change the filament. But it’s a quick action on the first screen.

You can do it with filament custom gcode... but I wouldn't bother

Is it possible to set a different z offset on PLA than on PETG in Prusaslicer? Im constantly changing "live z offset" when printing different types of plastic, but I know the values. I would like to put this directly in the slicer before printing so i dont forget to do it. Possible?

It is possible, but probably not worth it. Back in 2018, before the multiple sheet firmware option was available, many of us were thinking of ways to do exactly this. One user (name long since forgotten) did it by inserting custom gcode into filament profiles. The trick is to:

1. Home the nozzle to establish the "real" 0 position.
2. Move the nozzle to a known position relative to 0.
3. Reset that new position as the 0 position.

The gcode would look something like:

G28W ; Home nozzle
G0 Z1.02 F300 ; Raise nozzle to 1mm + filament correction (0.02)
G92 Z1 ; Set new 1mm position

(Note that you can't actually move the nozzle to 0mm. The software endstops stop Z at 0.15mm.)

This works, but in practice, I found it more trouble than it was worth. As time has gone on, I find I need to do fewer and fewer Live-Z tweaks for different filaments. I think this is from getting comfortable doing Live-Z on the fly and finding a good all-around level. Still, it's an interesting solution so I thought I'd pass it on.

A better place to do this is probably in OctoPrint as you could have it all in one place for ease-of-maintenance.

Okey then, prusateam!

I really wish for this feature bulit in the slicer *hoping*

You should not have to adjust the Z offset with every print.  

Z offset

No but everytime I change filament type

I THINK, (of course I don't know), that you have misunderstood the sheet profile changing procedure.
Shortly, you can have one sheet profile for PLA on Smooth sheet, named for example "PLA-SM", that filament-sheet combination have one Z-height. Then you can have another for PLA on Textured sheet, "PLA-TX", with a different Z-height, "PETG-TX", "ABS-SM", and so on, up to eight sheet profiles with different name and different Z-height.

This article, https://help.prusa3d.com/en/article/steel-sheet-profiles_1955 , explain it much better than I can 

Z offset

I did understand (I think)

I still need to remember to change sheet profile before I print with different filament, but if you could change this setting in slicer filament profile, then you don't need to think about it. That would be great

But for now I will use the sheet profile option 

Thanks😀
