Talk:BM Hot End v1
just to say :
the v6 use a peek support block and two bolts : http://www.mendel-parts.com/index.php/catalog/extruder/hotend-v6/hot-end-v6-complete-for-3mm-filament-with-0-50mm-nozzle.html
while the v9 (the one we can see in your picture) use the top brass to hold it with a nut : http://www.mendel-parts.com/index.php/catalog/extruder/hotend-v9/hot-end-v9-for-3mm-filament-0-50mm-nozzle.html
that's why I took the initiative to replace the "v6" by a "v9", sorry if that bothered you ^^'
