I’m looking to upgrade my Ender 3 Max Neo.
It has Marlin 2.0.8.3-HW-V4.2.2-SW-V1.4.7G firmware which I am unable to flash over to other versions of Marlin for some reason, it just crashes.
My board is a 4.2.2. Obviously as indicated by the note above.
I don’t mind changing the board out but I’m having a hard time finding any information on the 3 Max Neo and would rather not buy parts just to end up finding out that it’s not going to work.
Any help would be greatly appreciated.
I swapped to direct drive myself. Went with the Creality Sprite Pro since I already had mounted a CR touch to my print head.I thought it made the most sense for interoperability.
I actually went ahead and got a Sprite Neo and put it on the other day, installed Klipper after digging around for a printer.cfg for the Max Neo and finally finding one.
Now I’m just going through making sure everything is configured, levelled, and working properly as I have time.
If you have a filament runout sensor, the klipper default settings aren’t great. If the sensor activates, the printer shuts down after about an hour, losing your home position. With a part on the bed, you can’t re-home, so it’s a wasted print.
The mesh leveling isn’t automatic either. You might want to add either auto-load your default mesh leveling if you always use the same print surface, or put mesh leveling codes in the starting G-code section of your slicer.
I ran the pressure advance tuning and found that I needed a ton of pressure advance. My prints turned out much better.
I also got improvements by reducing the allowable deviation in the slicer (G-code files get much bigger, though), and I load files as STEP files directly in Prusaslicer. STL doesn’t have curves, it’s a series of planes. STEP files have geometric primitives and can have curves.
