Dear Home-Barista Friends,

I was wondering if any LM Strada MP or LM Shot Brewer owner or operator has experienced the same behaviour of the paddle: I have observed that between the paddle setting for pre-infusion (6 o'clock) at approx. 3 bar and full extraction pressure (below 7 o'clock) at 9 bar that there is only a little range to "surf" the pressure curve. That limitation forces the operator, in this case me, to be very sensitive while using the paddle.



Any similar observations? I made an illustration (based on LM's info graphic, hope they are okay with it) to make this behaviour more transparent.

Best regards,
-Malte

The GS/3 paddle is a different design from the Strada's. It does not have progressive preinfusion.

I agree, Dan - it is challenging to reproduce shots, close to impossible I would say. Especially if you try to imitate the brewing/ pressure curve of a lever machine. However, it is perfect machine for every roaster: small, precise, dedicated to espresso.

@Marshall: I am not refering to a GS3 Paddle, I am using the La Marzocco Shot Brewer, which is the small companion of the Strada MP (not EP).

Cheers,
-Malte

This "video" originally posted by Eric Calderwood in the GS3 forum shows, at least in the GS3 MP version, why repeatibility in the preinfuse region is tricky - La Marzocco GS/3 Mechanical Paddle : How it works

A little helix on the shaft might work wonders (thought experiment)
