There are many other options in the firmware for setting up upgrades, tuning, and other features. Read through the files configuration section to see all the features we’ve put in the firmware for you. Tested with a 164.4 x 164.4 x 245.4 mm vase model When compare the estimated print times on Creality Slicer, it shows 30 hours of the Creative 3D Ender-7 and the printing time of Ender-3 V2 is 44 hours, there is a 14 hours time difference, you did save some print time. I made use of mainsailos for my raspberry pi zero 2W, that already has all dependencies required to build the firmware as well

Finally, be ready to embrace the learning curve. Watch your prints, learn to spot trouble signs and keep experimenting. Discover efficient and speedy 3D printing with the Ender 7 3D printer by Creality 3D. Creality 3D has designed a core-XY structure 3D printer kit that you can easily assemble to produce extremely accurate models and parts. The Ender 7 is compatible with the materials: PLA filament, PETG filament, and ABS filament.

Design & Features

mm/s High-speed printing · High precision linear rail · Core-XY Structure · A customized high volume nozzle · Customized high-power motors · High-speed cooling fans · High-efficiency operational control algorithm · Minimalist aesthetic design In the configuration.h file there are printer models you can uncomment to tell the firmware what machine you are setting it up for. Uncomment means removing the // in front of a setting and you will be left with #define XXXXXX if an option is enabled. When the printer boots you may see the TH3D logo on your LCD, printers with low-end CPUs may not show a TH3D logo but all will show a Marlin screen with TH3D Studio showing on the version information.

Overall, I think the Ender-7 is a spectacular printer. It is a very rigid machine that you can push to some incredible speeds thanks to the linear rails and core-xy design. The advertised 250 millimeters per second is not just marketing talk. Combined with a decent print volume, you’ll be able to prototype large objects in record times with this printer. And if you slow it down just a little, you’ll have high quality prints. The extra features like power-loss recovery and filament runout detection are nice to have, even if they are a little buggy. The touch screen is pleasant to use, much more user friendly than the knob controls you normally find. Personal desktop-level product positioning caters to a small number of users with industrial fast printing needs. The full metal extruder with double drive gear ensures a strong grip, greater and more even extrusion force and a continuous and stable feed. The nozzle has a larger melting zone to help with such high speed printing. Melting is only half the battle though, once the plastic is printed, it also needs to be rapidly cooled down before the next layer is printed. This cooling is provided by dual cooling fans on either side of the hotend. The extruder also needs to be able to push enough filament, which the all metal, dual-geared extruder is easily able to keep up. It even has its own cooling fan to help prevent the extruder from overheating during long prints. The extruder also has a filament runout sensor, which will pause a print if you run out of filament. After you replace the filament, it’ll resume where it left off. First time using our firmware or having issues?

What I like

Aesthetically, I think the Ender-7 is a good looking printer. It looks great sitting on a table top, and since the bed only moves up and down, theres no risk of the bed hitting the wall or a passer by like some of the other Ender models. Sound wise, the motors are quieter than the fans when printing at normal speeds. When printing at higher speeds though, that’s when you’ll start to hear the motors. It is still comfortable enough to stay in the same room with it while it is printing. Partially Assembled but i hope you realize what changing the firmware does, for instance you no longer can use the lcd on the printer, so please really consider doing these steps to reduce your risks Currently, there are generally three sets of printing speed that 3D printers can support. The first set is has been grouped at around 40 to 50mm/s, while the second set prints at about 80-100mm/s. Meanwhile, the fastest set prints at around 150mm/s. Some printers may even print at a speed faster than 150 mm/s.” The review from All3DP.

If the build succeeds it is ready for you to upload to your printer. You will know if it was successfully built because it will show a SUCCESS in green at the bottom of the window in Visual Studio Code. Example of what a successful compile looks like. Your environment name may be different from what is shown above. If you aren’t versed in 3D CAD and building your own files, you’ll want to head on over to Thingiverse or one of the many other places to browse and acquire files for something you want to print. Creality released their new 3D printer Ender-7 in June 2021, it was advertised that this brand new product breaks through their other 3D printer of 50mm/s-100mm/s, can reach up to the speed of 250mm/s, which exceeds the normal printing speed in the market. There is no doubt that with such a fast speed printing, it can be a good way to save your printing time and make your work presentable faster. But does it work as accurately and consistently in the high speed mode as it claims to? Let's take a look. Design & Features Design Base, rear motorized and side static uprights, top frame with print-head, spool mount, print bed (not shown above) Overall, this is a good product with budget price for the 3D printer beginner. You will be happy with its performance, especially since it greatly reduces your wait time for print results.Power off your printer and put the SD card into your printer’s SD slot. Turn the power on. This will cause the printer to flash the firmware from the SD card to your printer CPU. This may take up to 1 minute on some boards. The linear rails reduce vibrations, stabilises and ensures ultra-fast printing. The service life is also approx. 78509 hours. The Ender 7 achieves these speeds thanks to its 42-60 stepper motors that provide ample power and torque to the belts. In addition, to guarantee precise movement even at such high speeds, the Ender 7 features linear rail guides for the X and Y axis, which should provide smooth and stable operation and long-lasting durability. Once you locate the .bin file for your board copy this to your SD card. This SD card MUST be formatted with FAT or FAT32 file system and most boards prefer a 4096 allocation byte size. Smaller cards (16GB or less) are better to use than larger ones for the best compatibility. If you have multiple .bin files listed, choose the one with the latest time & date on it.

I did run into a couple of issues while testing the machine. As I mentioned before, the Dragon failed about 14 hours into the 15 hour print. It left this beautiful piece of spaghetti though. What I believe happened was the cable protector for the hotend came loose during the print. During assembly, the protector is just shoved into a hole in the top of the printer. The protector came loose, allowing the cables to fall into the gantry, and it must have pushed the hotend causing it to continue printing off the side. A spectacular failure to look at. I’ll probably end up printing a retaining clip to help ensure it doesn’t happen again. It has a Core-XY gantry, which means instead of there being one motor for the X axis, and one motor for the Y axis, instead it has an intricate belt loop where two motors work together to move the hotend in the X and Y directions. This allows the motors to be stationary, and use the torque of both motors to control the hotend position. The gantry also uses linear rails for the x and y axis. These design decisions are what allows for the 250 millimeters per second print speeds. That's said there will be not much visible advance when you print small model. The printer speed comes out when you printer the big project, and it will goes smoothly when the printer speed accelerate.

Therefore, the triangle is the most solid shape. Therefore, it is also the most mechanically stable.
