Mounting
Mounting the Budaschnozzle is SUPER easy. Once your carriage is mounted and ready to go, place the Budaschnozzle into the carriage hotend hole. Line up the holes in the Budaschnozzle mount plate with the extruder mounting holes in the carriage. Put your extruder on top of the Budaschnozzle mount plate lining up the extruder mount holes with the holes in the mount plate and carriage. Push in the the screws that are compatible with your carriage (generally M4 screws). Screw on the nuts and tighten the screws. Bam, done.
Tip: Put a scrap piece of plastic filament through the extruder and into the hot-end before you tighten down the extruder. You do not need to heat the Budaschnozzle, just lightly push the filament down until it reaches the nozzle. This will align the filament travel space to give a nice smooth movement of the filament through the extruder and hot-end.

Special Notes
A thermal table has been created for the Honeywell 135-104LAG-J01 thermistor for use with the Buddhaschnozzle. The thermal table is included in the Sprinter firmware and is used by selecting thermistor 7 in the Configuration.h file in Sprinter. Change the line "#define THERMISTORHEATER 1" to "#define THERMISTORHEATER 7"
