Welcome back to Aurora Tech Channel. Today, I will review a 3D printer from BIQU, or better known as Big Tree Tech. If you like doing DIY upgrades, you may already have their motherboard or touch screen installed on your printers. I am going to review their flagship 3D printer, the BIQU BX. This printer has been around for 18 months somewhere between the end of 2020 and the beginning of 2021. It has some of the best hardware specifications among the mid-range printers, and some people even call it the 3D printer for Enthusiasts.

Let’s take a look at the hardware. It has a 7” touch screen, so it’s almost like a tablet on the right side of the machine. It supports a USB drive, a standard SD card, and a Micro SD card. There is a Raspberry PI connector at the back of the touch screen, so you connect the Raspberry Pi directly to the printer and use the same 7” touch screen. So, it supports 3 different modes: the classic Marlin mode, the touch screen mode, and the Raspberry Pi interface like the OctoBTT or OctoDash.

It came with the H2 extruder, which is one of the best extruders you can get for under $100, and the short filament path between the extruder gears and the nozzle. It has a dual steel gear with a 7 to 1 gear ratio, and even a pancake stepper motor can generate enough force to push the filament, as it’s compact and the total weight is just 203 grams.

Generally, the processor of most 32-bit 3D printer motherboards is a Cortex M3 that runs at 72Mhz, but this printer came with a Cortex M7 processor that runs at 400Mhz. The stepper motors are 0.9 degrees compared to the 1.8 degree ones used on most 3D printers. There are 5 TMC2226 silent stepper drivers, and the dual Z-axis are controlled by 2 independent stepper drivers that can use the firmware to align the level of the gantry.

It also came with an inductive auto bed leveling sensor, and there are belt tensioners on both the X and Y-axis. The hardware specifications of this printer seem nice to me. I would like to thank BigTreeTech for sending me this machine to review, and with that, let’s get started.
