Help Changing Hot Ends

I would like to replace the buddha schnozzle on my Taz4 with the v2 hexagon with minimal alterations to any other parts. I’m looking for any directions or advice I can get, Thanks.

How about detailed step by step instructions!

I’m hoping to keep the same tool head, just replace the hot end and replace some of the parts where necessary and update the firmware. Is this possible?

It is a different tool head so that might be hard to do really. You could use a number of the extruder parts and print the different parts you need, like the carriage, idler block, and add the needed wires for the extruder cooling fan that the buddasnozzle does not have.

Thanks. Will parts of the tool head be ok printed with ABS?

I believe that is what is used to print the parts.
