ForrwstHaines, I have had my Ender 5 PLUS for over a month, I'm waiting for Tim to announce a new upgrade path - replace the mainboard and the screen and EZABL. In the meantime here is what I like and my dislikes.
It prints very well, as good if not better than my two Ender 5's.
The Bed size, I can print things that were simply not possible for the Ender 5's. I'm printing a LED light bracket that is 400mm long by 15mm wide by laying it out on a 45 angle.
BL Touch - this is also my dislike, but it is better than nothing.
The glass bed- it will grip any print
it comes with a Creality standard hot end, extruder, bowden tube,and mainboard (noisy)
BL Touch, it works, but I have had to straighten out the pin a number of times. In my opinion the EZABL is so far superior, it never has to make contact with the print surface, no pins to bend or break and it seems much faster.
The glass bed, it holds on to any print, and will not let go until it cools.
The software on the mainboard, it is not terrible, but is very different, and does not provide much feedback when printing. I think you must have Octopie if you want to run this.
Filament out sensor, so far I have never needed one, and the Ender 5 PLUS is terrible, hard to load and it keeps blocking the filament. I have detached mine and left it hooked up on the back of my custom bracket
What I have modded so far:
I have replaced the stock hot end with a MicroSwiss kit. I'm not as much of a fan of Micro Swiss as, I have been it the past. I had trouble with filament jamming between prints, but I have it on both of my Ender 5's so wanted to be consistent.
SeeMeCNC extruder, again I have it on both of my Ender 5's so it makes it easier to keep everything consistent. This has been a marked improvement over the stock unit. It will not fit on the stock bracket. I have posted an adapter on Thingiverse.
I have custom profiles for both Ender 5's in PrusaSlicer 2.1 that fixes my problems with the MicroSwiss and uses the advantages of the SeeMeCNC.
I know t his is a long post, but wanted you to get some idea of what you are getting into. I was fortunate that I had the Ender 5's to get schooled and lots of time to investigate upgrade paths. The Ender 5 Plus is still an unknown machine to most companies and the community.
