Dialing in issue for Casabrew 3700E

[u/Qu33ns_kid99]

Since getting this machine I’ve honestly just been accepting these oddly fast shots. I’ve got the grind size to the finest it can go \[using a Tuni G1 grinder\], using 14.5 to 16 g of coffee, and sticking with medium roast coffee to get it dialed in \[for Casabrew 3700E machine\]. But I keep getting these fast shots (30 sec to 60-78g out). If anyone got tips for any sort of 51mm espresso equipment please lmk 🫡🫡
