this photo clearly shows the 16 bar gauge
at the top right side is a little white knob-- (the pump speed controller)
If you look closley at the bottom right side there is a little black lever-- (Line pressure controller)
I can pre-infuse and ramp up or down any pressure I choose
I can also ramp the pressure down to lengthen the shot without blonding and spend more time in the chock-let caramel phase of the shot at the end, some shots I let trickle at about 2-3 bar for a while at the end.
It is just a cheap machine I picked up for $15 in mint cond. never used.
the back gives easy access for mods.
I am having a bit of fun pressure profiling different beams
I am finding that 9 bar for 30 seconds is no longer relevant
What I do now is find the best grind for each bean,
then adjust the machine to that grind rather then grinding for the machine.
