Learning the Ellimatic and realizing that I'm having trouble yet figuring out where the water dance stops on a flush. Where on this video do you see the dance stopping? This 350 ml (yes, I measured what was in the drip tray) flush was done after a 45 minute warm up.

Yours never seems to settle down into one stream like mine does. Mine makes one stream of water more often than not. Some times faster than others. Maybe you need to clean or replace the screen.... Mine stops spitting out steam in about 2-3 oz and settles down in 4-6 oz range. I measure that from the number of shot glasses I toss. My shot glass holds 2 oz.
Or maybe the pstat is set really high. I have turned my pstat down.
I can also tell if it is over heated by how hot the shot glass is to handle. I cook a lot so hot things don't bother me unless they are really hot. The first two shot glasses are hard for me to hold to dump in the sink. The 3rd one is normal feeling. I know that doesn't help you much, but really you get the feel for it pretty fast.
Buying advice: GRINDER GRINDER GRINDER. Don't cheap out on the grinder.

Pulled the shower screen and dispersion plate for cleaning (they weren't all that dirty), and it looked like the dispersion plate was in upside down. Flipped it, and the end of the dance becomes more obvious. I'll probably pick up a spare dispersion plate and shower screen from espresso parts or directly from NS while there are still some available (although it seems the shower screen is the same as Oscar and other 57.5mm NS screens). Always a good idea to have key parts for vintage gear.
I still want to check the pstat setting, but I'm getting pretty good shots. Next up, working on microfoam.

Either you are way too hot and it is never settling down or it is too cold and it never is flashing to steam.
I suspect the latter though I suspect you are not far from proper temp as you say you are getting good shots.
The "dance" is the water flashing to steam and I never really see water flashing to steam which leads me to think you are a little cold.
You should HEAR the steam stop hissing like about the 10 second mark on the first video linked above, If you do not hear any hissing, you are not hot enough. You don't have a gauge on that machine so that makes it a little harder to know what is happening, I would be happy to have you bring it over and we could work on it together, adjusting the Pstat if need.
Another member here just starting with a HX machine was also having a hard time and his new Gioto was not quite hot enough either. He brought it over and I showed him the dance on my machine and after he warmed up the Pstat a little, his started working fine too.
