The Big Tree Tech / Biqu terminator hotend was not made for bed slingers. But that doesn't mean it can't be used on one!
This is designed to mount on a linear rail sitting on TOP of the X gantry. If your rails are top mounted, this should be fairly simple. I have a few versions of this terminator mount. This is one of the coolest hotends ever made. Only 200 were produced, so its quite rare in the wild!
