The BIQU H2 should be a E3D Hemera killer. Smaller and lighter for less money. The only problem is, some of them are lemons. In this guide and test I try out five to get a better picture as to their reliability.
The XChange system from printermods.com has just started shipping. THe H2 was a great match with two custom tool plate holes. There are also mounts available below to fit the H2 to a stock machine.
The H2 this video started with was originally supplied free of charge by BTT. They also supplied a free replacement. In addition to this, I purchased another with my own money for comparison. All opinions expressed are my own. If you get a working one they are pretty damn good. I you don’t, make sure Bigtreetech supply a replacement.
