Dialing in the Espresso

My espresso machine has been working well, but I think I was getting lazy in spending time to properly dial in my beans – but after spending a little time this weekend doing just that – I realized what a difference it really makes!

I was motivated after taking apart the grouphead trying to resolve some excessive water dripping from it – I was going to take the parts into a local shop and basically rebuild and re-gasket the entire grouphead. Once I had all the parts out, and cleaned everything up, I realized it would be a couple days before I could get to the shop – and I didn’t want to be without my morning espresso’s, leaky machine or not!

So back together it went – and shockingly, the leaking went away, and I also found that the shot lever actually moved with little resistance – much like it did when I first got the machine over a decade ago!

Dialing in my shots didn’t take long at all I found – don’t know why I thought it was such a chore. I have the machine dispensing about 2 oz. of espresso in 29 seconds, with the portafilter dosed with 19-20 grams of beans.

The Gecko goes on…

My printer has been idle for a number of months and this past weekend I finally spent a little time fixing up some wiring and actually printed a coffee grinder funnel prototype I started working on. The initial print was great – but after making some changes and starting another print job, I almost immediately ran into issues with blockages in the hotend.

I upgraded the machine with a genuine E3D Titan extruder and V6 hotend, but I’m still not impressed with their performance. Need something better – but what?

Update 🙂 I think I have a plan…

Mosquito hotend by Slice Engineering

Came across a company called Slice Engineering in the U.S.A., that has developed a hotend they are calling the Mosquito. The design is very intriguing, and it looks like it might be 1/2 of the answer I’m searching for.








Bondtech BMG-M Extruder

The other half of the answer is the extruder, and a Swedish company called BondTech has an extruder designed for the Mosquito – the BMG-M. I like the dual gear mechanism they’re using, and from what I’ve read, is a good step up from the Titan.
