How do you all keep your z home consistent? (self.vorondesign)

Title basically.

Obviously, cold nozzle + filament on it from my last print = the printer thinks the nozzle is lower than it actually is.

Preheating the nozzle helps some, but if I want true consistency I need to mechanically whipe the nozzle/grab the bit of plastic that oozes out with a pair of needle nose pliers.

I know nozzle brush mods are a thing, but aren't the hard on your nozzle? Does anyone have any alternative ideas?

This is basically what I'm doing now, but I would prefer less hands on because I'm constantly getting pulled in some new direction after I start the preheat.

So far I've only printed ASA on my Voron. Why would you use different offsets? To vary the amount of first layer squish or something else?

To keep the squish consistent. I assumed it was because the nozzle is expanding more at higher temps but it could just expansion differences in the material or something else I guess. My start up script is homing at nozzle temp - 75c or something like that, most people with a brush just do the home at temp so there is no change. And yeah I forget about it sometimes too ๐Ÿ˜‚

Sorry I just realized the way I described everything was actually pretty confusing. After every print I run a clean macro that moves the nozzle up front and heats to 230 and sits there. After about 10 minutes I wipe it then have a clean complete macro to cool down and move it back to the center. Then I start a print and the homing etc is all done at a lower temp, I can't remember if it's static or nozzle temp -75c or something
