    K3 touch mod

    I have an older model K3 touch with the timer control underneath the grinder which is a less than ideal place to put it so was wondering is it possible to get it moved to the outside of the machine similar to the later models? is there anyone that does mods to grinders? I have found consistent dosing has been an issue for me with this grinder, can anyone recommend a way to get consistency with it.

    With regards to the dosing: do you keep a level of beans in the hopper at all times? My experience with this grinder (the later model with the timer knob at the front and a proper scale of numbers on the collar) is that it works best with some static weight of beans (hopper 1/3 to 1/2 full). At least It does make a difference in consistency of the extraction flow rate. Truth be told,
    I rarely use the timer function and weigh the grounds instead, but most probably it helps your dosing as well If you keep the hopper halfway filled.

    I tired several times to dial in the timer feature on mine before giving it away as a bad joke, if I wanted a little bit more you had to operate the switch on the side again or I'd accidentally bump the switch again and end up with coffee that I didn't want.

    I changed the grind switch do another mains rated micro switch and rewired it, and now have it as a simple push to grind or bump grind, I can easily add the smallest of extra coffee if needed. I liked the idea of the timer until I had to use it, then decided on the current approach, which I much prefer. Mines the early style grinder also, timer underneath.

    I'll probably have to stick to manual push and grind then weigh the porter filter.
