Aether Refinery + Automated Assembly Line + Gonti's Aether Heart
Overview
Aether Refinery’s replacement effect doubles any event that would give you one or more 
, so: Automated Assembly Line’s triggered “you get ” will give you 2 when that trigger resolves, Gonti’s Aether Heart’s enter-the-battlefield trigger that gives will give you 4 when it resolves, and Aether Refinery’s own activated ability’s initial “You get ” is doubled to 2 as it resolves; you then may pay one or more as part of that same ability resolution to create an X/X token (see Ruling [2024-06-07] and Ruling [2024-03-08]).

Automated Assembly Line deals combat damage and its triggered ability (“Whenever one or more artifact creatures you control deal combat damage to a player, you get .”) is put on the stack; when that triggered ability resolves you will get as part of its effect and the event of gaining that is subject to Aether Refinery’s replacement effect so you receive 2 instead (Ruling [2024-06-07]).

Gonti’s Aether Heart enters the battlefield and its triggered ability (“Whenever Gonti’s Aether Heart or another artifact you control enters, you get .”) is put on the stack; when that trigger resolves you would get , and Aether Refinery doubles that event so you receive 4 instead (Ruling [2024-06-07]).

To use Aether Refinery’s activated ability you activate it (announce activation and tap it as the activation cost) and put the ability on the stack ; when that ability resolves it does its steps in order: first “You get ” resolves and Aether Refinery’s replacement effect doubles that gain so you get 2 instead, then you may pay one or more as part of the same ability resolution; if you choose to pay N (you cannot pay more than you have) you lose those N counters and create an N/N black Aetherborn token as the final part of the ability resolution (Ruling [2024-03-08]; Ruling [2024-06-07]).

If you activate Automated Assembly Line’s Pay ability to make a 3/3 Robot, you must pay three energy counters (losing them); Aether Refinery’s replacement effect only changes how many you get, not how many you pay, so the cost to activate Assembly Line’s ability remains three that you must have and pay (lose) when activating (Ruling [2024-03-08]).

When any ability or effect tells you “you get ” or “you get ”, Aether Refinery’s replacement effect applies to the event of getting energy and doubles the number of energy counters you will receive. Concretely: Automated Assembly Line’s trigger that gives you will give you 2 when that trigger resolves; Gonti’s Aether Heart’s trigger that gives you will give you 4 when that trigger resolves; activating Aether Refinery’s 
ability will give you 2 (instead of 1) as the first part of that ability resolving, and then you may pay one or more (up to the energy you have) as the second part of that same ability resolution to create an X/X token equal to the amount you paid (Ruling [2024-06-07]; Ruling [2024-03-08]).
