I am currently printing Covid-19 face masks for healthcare professionals and both this printer and my Ender 3 are currently dedicated to this, running 7 days a week, 16 hours a day and sometimes longer, for the last two months.

Other than replacing the extruder with a cheap all-metal unit, fitting the Creality silent board and replacing the lead screw brass bearings with cheap delrin bearings (to remove z axis backlash) the printer is running stock.

The only real gripe I have is that after discovering Octoprint introduces artifacts even when hosted on a Raspberry Pi 4, I'm back to printing from SD. The problem here is that unlike the Ender 3, the Ender 5 + stock firmware doesn't have a refresh SD option. If you add a standard SD to micro SD adapter cable, like I did with the E3, then if you change the SD card the printer doesn't pick this up and the lack of a refresh option means you can't update the list of files to print without unplugging and replugging the adapter cable into the controller board - which kind of negates the whole purpose. If Creality could add this feature I'd be overjoyed.

The only other problem I've had is that sometimes I'll get a temperature trip warning during hot-end warmup to 255 degrees. This I think is a firmware issue because if I heat the hotend to 240 then 250 then 255 I don't get the error - and I've never had it fail during printing either.

Print quality is excellent. The slight Y axis ringing on the Ender 3 which is a consequence of the large moving Y bed mass (with a glass plate fitted) is not evident on the Ender 5 and the solidity of the mechanical design is excellent - I think this is clearly the way to build large-format printers. Bed stability and flatness are very good. Using a 25mm square piece of 0.5mm thick thermal silicone sheet in each corner, you do not need any clips to secure the glass plate.

Hello,

This is a great printer with one draw back out of the box. The filament sensor is not working. I had to disable this or it would not print. The printer works great besides this key feature. I am disappointed and I am working on solving this. Bed leveling is so easy, print quality is amazing, touch screen is great.

A very stable platform that when tuned can produce amazing prints.
Pic just pulled off plate directly after print.

This is an incredible machine and print quality. I would have given an easy 5 stars if the silent motherboard was pre-installed. It is a noisy machine but that is the only complaint so far.

I have after a long time finally assebmled the unit and I love the printer.
The semi assembled parts were not correct and had to be adjusted, and that was a bit weird, they could have been correct or not together at all. I even had one screw that were round and couldnt be adjusted (pointed it out on the picture with an arrow). But it still makes the prints great, So I guess I have to live with it. It is also a bit noisy and good to make a box for noise reduction if running in the same room as where you are.
