Review on 🖨️ Enhance Your Printer with the Innovative BIGTREETECH Display Controller by Tony Wilson

***UPDATE JULY 22, 2020***: After speaking to the company about the faulty board, they walked me through a few basic steps to ensure the MOSFET was blown , and then promptly sent it a replacement board. I'm updating my rating to 4.5 stars based on the level of customer service. The newer version of this board seems to fix the MOSFET overheating issue, but if you're still interested in the 1.2 board I'd recommend just putting an extra heatsink on top of the MOSFET chip (it's marked in the test photos) and making sure If you have fans on the circuit board is completely free of obstructions. ***Original Review***: Overall, I really like how the community is supporting this hardware. Firmware is easy to find and download, and community support is available for most issues. The board is fully interfaced with the Ender 3 and is usually updated to the latest Marlin FW. Touchscreen: This is (almost) a replacement for the E3. (There's a reset button on the circuit board that doesn't have a corresponding hole on the mounting plate.) You can toggle between the dial and the color touchscreen setting. I mostly use the touchscreen, although that's fine. The menus are a bit disorganized and it's difficult to access normal functions like disabling steppers, manually moving and saving settings, or resetting the EEPROM, requiring deep dive into the root menus. There is no clear step-by-step method for leveling the bed, particularly for finding the correct Z offset, as you cannot go below the zero mark on the "Set Z-Offset" screen. Motherboard: Great setup as a clone. for standard E3 board. There is some confusion as to where to connect BLtouch, if applicable, but the answers are easy to find in the community resources. It's nice to be able to directly download hex files for firmware updates as my stock board didn't have that capability (although it was advertised as having it). My biggest problem with the motherboard is that the bed heater MOSFET burned out after 2 months of use. I use a Noctua board digital buck fan and have never had overheating issues. It's worth noting that the standard E3 board has the largest heatsink of any board mounted on the same MOSFET. Also, the newer V2 board is twice the size of the MOSFET, which leads me to believe this is a common problem. if you can program to change the display menu. Also don't forget to put a heatsink on top of the MOSFET for the bed. I've included an image showing the location.
