Jim - I did revert the unit to its stock state for now. I'm hoping the R&D they put into the unit is going to help me avoid endless fiddling.

Switching to a stiffer spring also changes the MaraX's stock pre-infusion pattern correct? In other words, there will be no pre-infusion with a stiffer spring, it would depend on using the flow control paddle to do so?another_jim wrote:When they added flow control, Lelit replaced the the stock E61 preinfusion spring with a stiffer one. The very soft spring in the Mara X is going to exacerbate the problem. Have you made the replacement?
FWIW, I think you are going against the Mara's "don't fiddle with the pressure or temperature, just make your d*mn shot" philosophy. But the fairly precise temperature controlled group head makes it an attractive target for adding a pressure mod.
On another note, can anyone who has added flow control with the stiffer spring to MaraX confirm that this makes the paddle-to-pressure response more linear and predictable?

Yes, the Bianca does not use the preinfusion cylinder at all. The flow control acts as a jet. So the initial position of the paddle determines how quickly the pressure will ramp up, regardless of the spring. I have worked with machines that have the regular spring plus paddle. They are a little mushier; the Mara will be a lot mushier.thecatch33 wrote:Switching to a stiffer spring also changes the MaraX's stock pre-infusion pattern correct?
