Das der Ender3 ein Verkaufsschlager war und immer noch ist, muss man nicht groß schreiben. Mit dem Nachfolger dem Ender3 V2 hat Creality einen würdigen Nachfolger gefunden, zumal diese für knapp 220 Euro zu bekommen ist. Nur kennt man es, dass die Hersteller selber keine richtige Zeit in die Firmware stecken und man doch noch einiges raus holen kann.

So hat es auch der User „mrisoc“ gemacht, denn ich möchte nicht wissen, wieviele Stunden er in die neue Professionelle Ender3 V2 Firmware gesteckt hat. Es ist eine Menge was er hinzugefügt oder verbessert hat und es macht aus meinen Augen auch Sinn. Der Drucker macht Stock recht gute Arbeit wie man sehen konnte und mit der neuen Custom Firmware und einigen Mods ist es ein gutes Kaufargument. Ich schreibe Euch hier mal alles rein und kann mich im Namen vieler nur bedanken, dass er seine Zeit kostenlos für Euch investiert hat.

This firmware is based on Marlin for the Ender 3 v2. It has the serial port speed settled to 250000 bps for improve communication speed and avoid the errors relative to buffer underruns, please change settings in Octoprint/Prontface/Cura, etc.
