Solved Is there some way to prevent extruder from gobbing bed during autolevel?

I have in my end script

G1 E-15 F300 ; retract 15mm filament speed 300

but its still emitting filament during the autolevel of the next print which is leaving hard to remove gobs of filament all over the bed, i think its because there is still filament left in the nozzle even if its retracted. Is it possible maybe to do autolevel before the hotend heats up?

 

Yes, I auto level before heating because I use Zebra Plate/Skin/buildTak/Fleks build surfaces that will be melted if I auto level with the hotend hot.

What software are you using for slicing?

 

If you use that approach make sure your hot end is very clean first. Even a little hard filament stuck out on the hot end can through off the leveling and I've always seem some leftover after the print is done.

 

im using s3d, it doesnt give any option to run scripts before heating, it goes heat -> autolevel -> print

 

Unfortunately bed plates (im using pei) are the only way to make use of the full build area since they work at room temp. So basically id have to wait for to automatically heat it up, then wait for it to cool down to do the autolevel, then tell it to heat back up again, ugh.

 

So autolevel only has to be done per session, not per print? Because i could run it manually if thats the case.

 

Yea been doing it like this for a year. I have to make sure i use tweezers to keep the nozzle clean as its cooling down. Sometimes i have to heat the nozzle up clean it then kill the heat. Its a bit of an annoyance but not bad. Even if using glass I like to clean the nozzle anyway or it leaves boogers everywhere.
