It's another #FreeCADFriday and I share another printable design created with @freecad!

I made magnetic tags to label the printer configuration. This is an easy way to prevent material or nozzle size mixups.
I place them where they are visible through the camera so that they can be seen via #OctoPrint.

Mein Core One hat gestern das Filamentsensor Upgrade vom + bekommen.

Das ist echt durchdacht: man kann mit einem Schalter nun einstellen, dass die kleine interne Klemme keinen Wiederstand hat um flexibles Filament einzuführen.

Es war allerdings eine Fummelarbeit den Sensor wieder zusammen zusetzen. Man musste dazu zwei sich abstoßenden Magneten bändigen. Und alles dann inkl Griff, kopfüber auf die Außenwand schrauben (dafür hätte man gut eine 3. Hand gebraucht) #Prusa #CoreOne #3dprinting

Moved the #CoreOne from a LACK to a BROR table (metal frame) that I also installed leveling feet on. Pretty great. No more eek-eek-eek-eek when it gets moving.

Also comparatively no effort involved. It just costs 10 times more.

Does the #CoreOne need lubricant on the z-axis screws or not?

Finally took the time to publish another oddly specific model for #3Dprinting.

Průša CORE One+ Spoolholder for 250g mini spools (eg. Buddy3D, Amolen)

If you’re occasionally using tiny 200-250g spools, like they come with variety packs, filament tasting sets or generous samples, this model is a reliable solution to spool-wobble.

Locks into place like the original spool holder, but works reliable with tiny spools.

#Prusa #CoreOne users: Do you find that the filament retract feature is actually helpful? I don't change filaments that much. It *does* however produce a stick of filament I keep having to dispose of.

I don't use this on my MK4S as it completely does not work.

There is in fact no calibration procedure for the side filament sensor. You can’t fail QA at the factory if you just don’t Q the A!

It might just be an issue with a magnet not being pushed in far enough, but regardless it’s going to require complete removal of the side panel. Love to get all these basic-ass printer assembly 101 mistakes.

I almost don’t want to bother because the INDX setup obviously doesn’t use this sensor at all, but that would leave me with no way of doing filament runout properly.

I did fix the z-axis binding, I think. I printed the alignment tools but I think it was really just the screws being too tight. Tighten the screws, but not Too Tight!
