My M58 at home isn't left very long these days, so the PID doesn't have time to get very hot. But all the machines I've interacted with eventually will get quite hot (and the buttons being metal makes them more conductive than typical plastic PID buttons). I recommend making PID changes before this, but also it helped me get faster and more coordinated with my touches
Hah, right you are Ben! I'll make sure to quicken my pace for PID-related adventures.
Also, LUCCA pro-tip: when the PID firmware revision shows 1.02 (on startup), you only need to hold the up and down arrows for the latter half of the 1.02 display time. It will still enter into the programming, and you only need to hold the buttons for just shy of 2 seconds.
Here's an unrelated question, though: my joysticks (still nicely lubricated with Dow 111) occasionally do not return to center, and hang to the side. It is not far enough out to engage the steam, but what might be causing that?
