Review on 🖨️ High-Performance Printer Auto Leveling with TMC2209 Powerful Motherboard by Aaron Collins

I heard about this printer just before it was released and was curious if the plastic base would hold up. However, this printer was absolutely amazing, with a very simple 6 screw assembly process and zero platform alignment. It was mailed to me in a huge box inside an even bigger box and was wrapped in thick white foam. It is divided into two main parts: the Z portal and the base. The base is made entirely of injection molded plastic, but has multiple aluminum profiles at the top for rigidity and bed guidance. It's quite thick and the right shape. I removed the bottom metal plate to check what was under the hood and saw an Eryone 32-bit motherboard with tmc2209 drivers on all stepper motors. The PSU isn't Meanwell, but it has a fan that only turns on when the PSU is under load, and it's nearly silent when I use it. The wiring is clean and after checking all the connections, they are screwed tight. I looked at the hot end before completing the build and it uses an all metal heat break as well as a copper plated nozzle. This means the hotend has to withstand temperatures well in excess of what you would typically see on a budget Teflon-coated thermal separator printer. I personally also love electroplated copper as it gets rid of plastic like PETG which means no nozzle drips. The bed uses a textured glass top on a standard heated aluminum bed. The included clips hold the bed very securely while remaining unobtrusive, which is a lot better than the alternative tie clip I've used in the past. Heated connectors are protected by an orange plastic strain relief clamp. One thing to note is that the bedposts are 100% solid, there are no springs here. In my testing, the bed was a nearly perfectly flat surface with 0.02mm of flatness across the entire board. Eryone really knocked it out of the park with this buildplate. It's a bit small, but the printer's small footprint is good if you're short on space. The gantry attaches to the bottom of the printer with four screws and is much more rigid than I would have expected with a plastic base. There was no wobble and the sculpted tread holes kept it perfectly level, no adjustment. I just did a quick level with the measurement marks on the tabs to make sure both sides of the X gantry were level and then turned on the printer. In every respect, the Eryone Automated Platform Level Sensor is a BLTouch. It works identically and in my testing works exactly like the original. That's great, because with the fast 9-position mesh probe, you can say goodbye to the need to re-level your bed. Solid bedposts ensure the bed frame you save will never change. This is a huge win, especially for new users who would otherwise spend hours trying to get the perfect bed height without any experience. There was a lot of information on the supplied microsd card. Printer firmware hex files, three test STL files for printing, slicer profiles, tutorial videos and PDF files. I printed out one of the test files with the filament included, which ended up being a 20mm calibration cube. It turned out to be better than I could ever hope for for a freshly assembled, unconfigured printer. I had no problem staying bedside with the factory default Z-Offset, so I haven't found it necessary to change it with the included LCD wizard since. The final print had no Z-stripe issues and had excellent surface quality, and measured with calipers the width on all sides was 20.02mm meaning it was a near perfect print. I'm still doing more tests with my ER-20, but it was easy to use. It takes about 30 minutes to set up and start printing after opening the box. This is the MOST killer printer for beginners with the hardware and power to prove it. I would definitely recommend this to people who don't want the hustle and bustle but want a 3D printing experience. generally obtrusive. The entire printer is actually very quiet when idling and printing. With an Ender 3 Pro, this thing easily has 2-3x louder fans. The tmc2209 stepper motor drivers are silent and UART compatible in software, which means you don't have to fiddle with potentiometers on the motherboard to set the stepper motor voltage.
