Prusa mk3s+ with mmu2s and a mini.
Mini pretty much immediately upgraded with the Bondtech IFS extruder - great extruder, but won't buy Bondtech kits again as their documentation is horrible. Mainly had the mini for flex and abrasive initially, as I didn't want to mess with nozzle changes on the less accessible mk3s, and didn't want to mess with flexible with the MMU. Upgraded it earlier this year to Revo hotend - had a bit trouble due to another delay with their hardened nozzles, but figured out you can get Revo nozzles from China with pretty much the same tolerances for 5 EUR each, so was just running through them until I finally got my obxidian nozzles.
Mk3s ran stock with MMU for a while, printed the TZB extruder in PC-CF earlier this year, switched to TZB-firmware, and also moved it to Revo - didn't have much issues with MMU before that, but things are very noticeably faster now, plus even very flexible flex just works.
Not sure if I'll upgrade it to the MK4 - the load cell setup is intriguing, but I don't want to give up the Revo setup, so I'll probably wait and see if mods will come up allowing me to use both.
Gerade bei weitlaeufigen Stationen ist ein Aufzug nicht ausreichend. Schoen dass da endlich was passiert - eigentlich haette das ein vor 20 Jahren abgeschlossenes Projekt sein muessen.
Einige Stationen hatten auch Treppen oder Treppenaufgaenge wo vom Platz/Layout mindestens Platz fuer Rampen/Keile fuer Kinderwagen, teilweise auch ein Umbau fuer odentliche Rollstuhlrampen moeglich waere - das sollte zusaetzlich zum Aufzug auch passieren, wo auch immer moeglich.
