Kingroon KLP1 CoreXY Printer Review

Thanks to products like the Kingroon KLP1 CoreXY Printer, 3D printing is becoming more and more affordable and accessible. This 3D printer brings high-speed printing directly to your home and even features an enclosed work area to keep projects safer. I had the pleasure of testing the printer to see how well it really works.

Overview of Features

The Kingroon KLP1 CoreXY Printer features a mainboard, complete with Klipper firmware. And yes, you can tinker with the firmware, though you really don’t need to. Thanks to Klipper, you get much faster printing. In fact, the KLP1 supports 500 mm/s high-speed printing with 10,000 mm/s² acceleration.

With faster printing speed comes increased vibration. However, an ADXL345 module helps compensate for the vibration, giving you smoother printing in less time. There’s also auto bed leveling to prevent time-consuming manual-leveling between prints.

A 5:1 gear ratio is all metal and includes 9500 rings 5015 bearing fan, a CHC hotend and smart microprocessors. This all means the extruder with a 0.4 mm nozzle is better than ever and includes an improved cooling system from previous Kingroon printers.

Linear rail guides on the X and Y axes aid in giving you far more accurate movements. This also reduces wear and tear. Kingroon estimates the printer has a life of around 78,000 hours.

A small holder on the back keeps the filament in place. A sensor ensures that your project stops in time for you to load more filament to continue printing.

A small touchscreen lets you control the printer. Or, connect the printer to your network via a wired or Wi-Fi connection. Then, control it with a Web interface on your computer or mobile device.

The all-metal hot end with ceramic heating core heats up quickly. It supports a max heat of 300 degrees Celsius. The magnetic plate removes easily to clean when needed.

Tinted panels enclose the entire machine, with the exception of the filament spool. This keeps your project safer while printing. Two doors let you check in at any time.

The machine itself is 15.74 in x 16.54 in x 16.54 in. It supports just over an 8″-square printing area. It also has three USB ports and an Ethernet port.

In the Box

The Kingroon KLP1 CoreXY Printer does require some assembly, which can be tedious. However, everything you need to put it together is included. The box includes:

• The printer itself
• Panels
• EMMC card reader
• Power cable
• Diagonal pliers
• 10 m filament
• Screws
• Hex wrenches
• Data cable
• Touch screen pen
• Hard steel nozzle
• USB cable
• Instruction manual
• Assembly guide
• Filament holder

The USB drive has copies of the instruction manual and assembly guide. It also has software, including UltiMaker Cura, and necessary files to connect Cura with the printer. There are detailed instructions on exactly what files to copy into Cura’s program folders. Once you do, it’s super easy to add the printer to the software.

While everything was packaged well, I was disappointed to see the screen on the printer was scratched and one of the side panels had a noticeable chip. After learning about this issue, the Kingroon team is optimizing packaging and communicating with the logistics company to improve transportation.

Assembly and Setup

Assembling the Kingroon KLP1 CoreXY Printer isn’t the most pleasant experience. I really wish the panels were already attached. The screws are tiny, hard to hold on to, and a few of the holes were already stripped out and wouldn’t hold the screw at all. Luckily, enough held so that it wasn’t a problem. While the front door panel didn’t fully line up as it should, Kingroon has assured is that his occurrence is rare and is likely due to installation or logistics.

I received an early model of the printer with everything in the Chinese language, by default. It made it difficult to get through the instructions. English or a local language is the default on more recent models.

Setup isn’t difficult at all. You don’t have to connect to the Internet to use the printer. However, I opted to connect to Wi-Fi so that I could bring up the settings and controls on my laptop. Trust me, it’s much easier to see everything this way. The instruction manual shows screenshots for both the printer’s touchscreen and the Web interface. Just follow along, and you shouldn’t have any problems.

The only hiccup I had was getting the extruder to load the filament. The filament loaded into the tube with no issue. However, the web interface didn’t seem to send the command to the extruder correctly. I had to do this on the touchscreen.

The touchscreen isn’t sensitive. In fact, it rarely recognizes the touch of a finger, even when pressing more firmly. Use the pen. It works well. I just attached it to one of the door handles. (There’s a top and front door.)

Kingroon already has Benchy (a popular file for testing parameters for 3D printers) uploaded in the Web interface for a test print. I used the fast version to ensure I had everything on the printer set up correctly.

I honestly didn’t expect things to go well. A first print usually has some issues. This was pretty much perfect. The cute boat printed in around 20 minutes. It stuck well to the PEI sheet and removed easily after cooling.

Using the Kingroon KLP1 CoreXY Printer

Thanks to the files included with the printer, slicing projects in Cura with the correct parameters is a breeze. I still want to play around with the settings just a bit for some projects so that they don’t have as large of a base. But every project I tried printed perfectly the first try.

The bed and nozzle heated quickly. I’m not a 3D printer expert by any means, but I can say this is the fastest and most accurate printer I’ve worked with.

Every file I tried printed quickly. The longest project was a three-inch tall lucky cat bank that took around an hour. I never had a single project slip off the mat during printing.

Personally, I love having the machine enclosed. I don’t have to worry about dirt and dust getting in and causing problems. It also creates a more temperature-controlled environment.

It’s not a loud machine, either. Yes, you’ll hear some humming and rumbling, but you could easily use this in your home without much disturbance.

Final Thoughts

While the Kingroon KLP1 CoreXY Printer has a few flaws, it’s a great 3D printer for beginners and hobbyists. It’s fast, accurate, and easy to start printing without playing around with settings too much.

It’s great that Kingroon is listening to feedback, that it has taken care of the language issue, and is working on the shipping. It would also be nice if a slightly more sensitive touchscreen were used.

Overall, I thoroughly enjoyed using it. Try the Kingroon KLP1 CoreXY Printer for yourself for just $339 after applying the $40 off code KLP1.
