Yeah, some people experience leaks, some people don't. It really depends on the hot end and the assembly.
As for the short "melt-zone", basically I am referring to the length of the heated portion of the hot end. A short "melt-zone" means a short heated portion, which translates to a smaller volume of molten filament in the hot end, which in turn results in less "ooze" from the nozzle. 'Ooze' is caused by gravity acting on the liquid molten filament pulling it down through the nozzle (you can test this by turning your printer upside down! No more ooze... but it is awkward having your printer upside down). By decreasing the volume of molten filament in the hot end, you are decreasing the pressure that gravity is exerting on the molten filament and therefore less plastic oozes out of the nozzle tip.
Hence, shorter "melt-zone" = less "ooze" ---------- longer "melt-zone" = more "ooze"

Hello Everyone,
The campaign is almost fully funded with over $2500 in contributions! Thanks to the latest contributors.
A few updates for you all. RepRap Core Developer Brad aka "Sublime" is working on a review and Michael "ZennmasterM" Zenner will receive his prototype for testing in the next few days! We will likely be seeing the reviews in the next week. I also managed to get in contact with Richard Horne. He is currently tied up with work but he happily agreed to do a review sometime in the next few weeks!
Recently I have been working on getting my website up and running. It should be up in the next few days so I will keep you guys informed when it goes up.
The components are starting to arrive! Earlier today I received the bulk order for the thermistors and resistor heaters for Prometheus. Most of the components are already on order so I am just waiting for them to arrive. The production run for the machined parts is well under way and going smoothly as planned.
Let's keep this campaign going!
Happy printing :-)
Eric
