How do you all keep your z home consistent? (lemmy.world)

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?

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 😂

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
