I’m a new-ish barista working in a chain shop. We use a Mythos 1 and recently we brought down a new grinder, the company sent someone to have a look at it and make sure it was running as it should.
I’ll dial in the machines every morning, using 18g dose, 36g yield, 25-30seconds run time, however since we had someone look at the machine the doses have been so irregular dialing in is getting so difficult. I’ll weigh it once, 18.8g, the next dose will go down to 18.4g by moving the dose time down, I’ll remove another 15 seconds or so and the dose will somehow go up to 19.2g and so on. The grinder has the front panel taken off and the burrs brushed out every other night but that doesnt seem to be helping at all?
