I've been using a Mythos for a little over a year and it has been mostly great... until recently. In the morning I'll turn the grinder on, fill the hopper with beans, and wait for it to heat up a bit before dialing in. Lets say that my dial in is: 17g-37g-34s, and I'm pulling shots at those specs wonderfully and consistently until... the first rush of the day, I'm grinding shot after shot and the machine gets hot so the cooling fans kick on, and now I'm screwed! Doses are no longer consistent and are off by a gram or more and the shots are pulling for 4 or 5 seconds longer to hit the target yield...WTF? I adjust my grind setting coarser to compensate and to try to get things back on spec, but there's no consistency. Some shots are only off by a couple seconds but some are off by a lot more.
Once the chaos subsides and the grinder gets a chance to cool down, the fans shut off. After adjusting my grind setting and dose-time back to where they were originally, things become consistent again and it's all back to normal... until the next busy rush.
Anyone else experiencing problems like this, or have some advice for me?
