• the part cooling fan is as loud as a vacuum cleaner, and the cooling fan of the power supply is almost as bad.
• the large volume plastic housing of the printhead seems to hit resonance frequencies pretty often which causes the printer to emit loud ÖÖÖÖÖK ÖÖÖÖÖK ÖÖÖÖÖK noises which drown out even the fans. It is annoying to run this thing overnight even if I put it in the far corner of my rather large house. It would be impossible to use it in a flat with neighbours even if you live alone and wear earplugs.
• the printer takes FOREVER to actually start a print, even if you skip the painfully slow and time consuming bed leveling procedure. It moves up and down, backwards and forwards, randomly nuzzles the bed in several places even though you told it to skip leveling. It inexplicably heats up and cools down the nozzle and the bed between the various, mysterious steps and you have to wait for it every time. It is driving me bonkers.
• it is seemingly impossible to preheat nozzle and bed so you can start printing immediately after getting the .stl file in the printer. I can do that esily with my 3 Pro and my 3 S1, but not with this one. It is necessary to go through all the previously mentioned steps if you want to watch the first layer so you have to wait and stay with the printer for several minutes.
• it appears to be impossible to adjust the z-offset whlle the printer lays down the first layer. My skirt lines, brims and the first layer all have way too much squish and changing the offset in the display in the expert mode has no effect on the nozzle whatsoever, no matter whether you click on save after changing the value or not.
• the bed leveling doesnt seem to work either, I printed a rectangle half the size of my palm and one side was perfect from the first 0.2mm layer to the sixth (that means it cant have been overextrusion), the other side showed the ploughed-furrows look of excess material. That means that that part of the bed must have been significantly higher than the other, despite having done several bed leveling rounds previously. The printer seems to forget the results whenever you switch it off.
• print quality is noticeably worse than what I get from my 3 S1, even though I am curently running the V3 Plus at less than a quarter if its advertised speed of 600mm/s and with the accel toned way down too.
• sending files to the printer by WLAN (one of the best parts) only works with the Creality Print 5.1 slicer, which sucks balls. It hasnt got the “lay object flat on buildplate” function that Cura has (or rather it is not nearly as good), it has only got the most rudimentary of combing functions, and you have to set the bed temperature in the frigging FILAMENT settings, not among the other settings! That one drove me nuts until I found the solution through extensive googling. It also barely lets you adjust the z-seam andwhen I thought I had it the way I wanted the slicer fucked it up in the weirdest of ways that I have never experienced with Cura.
• I set up a custom printer profile in Cura and tried to create g-code for the Ender with that, but you can only feed it to the printer with a USB stick and I have already had the printer do the most random things and throw up error codes with that method. My computer says there is already a problem with the brand new USB stick that came with the printer so we will most likely never find out what the problem was before I send this POS back.
