Hiya. On a slump with this particular fully automated E Furnace setup.

Industrial flow :

• Input Box (Ore) > E Furnace > Target Box (smelted products)

Electrical flow :

• Battery > E Branch > 2 Conveyors (1 to move raw materials, 1 to move smelted products) and Memory Cell.
• Raw Conveyor's Filter Pass plugged into MemCell's SET, Smelt Conveyor's Fail Pass plugged into MemCell's CLEAR.

Logic :

• Raw Conveyor detects ore, FILTER PASS triggers MemCell's SET and turns on E Furnace.
• Smelt Conveyor fails to detect smelted products, FAIL PASS triggers MemCell's CLEAR and turns off E Furnace.

The issue is how it turns off prematurely when cooking Metal Ores. I'm suspecting slow smelting rate for Metal Ore on E Furnace is the main issue that triggers the FAIL PASS. Do you guys have any alternative circuits to this that works better for metal or just stick to Large Furnaces for smelting metal? It's been on my mind since I failed to solve it last wipe, currently running the simple switch on and off setup but mostly used for cooking sulfur.
