Longer LK5 Pro 4.3-inch Touch Screen FDM 3D Printer

This LK5 Pro meets the following characteristics: FDM compatible with ABS, PLA and derivatives with a diameter of 1.75 mm. Maximum print volume of 300 x 300 x 40 mm with precision between 100 and 400 microns. The single 0.4 mm nozzle heats up to 250°C and deposits the filament on a heating plate. The printer is controlled by a computer via USB cable or by the large 4.3 inch color touch screen with new interface and an SD card.

On a technical level, the L54 Pro from Longer uses an open source Marlin firmware, a Bowden extruder and a silent TMC2208 driver. The Pro also adds automatic leveling.

The power failure recovery and the end of filament sensor are standard on the printer, whose maximum printing speed caps at 180 mm/s. However, the manufacturer recommends varying between 60 and 80 mm/s on the LK5 Pro. The power supply has been placed under the print bed of the LK5 Pro.

The Longer LK5 Pro is good. It can definitely do something. Not really above average better than others in its price segment, but definitely not worse either. I can imagine that due to its stable construction and the overall good workmanship with a little optimization, it can easily put the Ender 3, maybe even the i3 Mega in your pocket. Unfortunately, he just doesn’t manage to do that directly “out of the box”.

Which then really spoils the first impression. The fact of these completely superfluous little faux pas, which the manufacturer makes here, does not allow the LK5 Pro to rise to a top position with a clear conscience and therefore not recommend it unreservedly. A beginner should very quickly reach his limits here and lose the fun of his new hobby immediately if he gets a copy like the one I have.

Other manufacturers can definitely do that better and do that too. I certainly had one or the other inadequacy even with devices from several hundred euros to just under the 1000 mark. But not so many and not in such a way.

An experienced user will have to spend less time and energy here to get the printer going when it arrives like my copy. Therefore, I cannot completely remove the printer from a list of recommended printers. I would only advise beginners to look at the potential sources of error here and then decide whether they are confident enough and, if necessary, are willing to put money on top of it for necessary spare parts.

Once eliminated, I trust the Longer LK5 Pro, like the Alfawise U30 Pro, to have a high potential for high-quality prints.

Specifically, this means that the base plates have to be removed upon delivery, the positioning of the Z end stop has to be described differently in the instructions, although it should be updated anyway, the axes should be assembled a little more carefully ex works and as a safety aspect the Power supply cover can be extended at the back so that the gap is removed.

After that, this is a top entry-level printer that is sure to deliver a high quality with the first prints that please and makes you want more.
