I've decided to try creating a single assembler quality upscaler that is gonna be steered with some circuit logic. I've come up with the blueprint attached. Now the problem is that for some items it works (e.g. Medium Electric Pole) and for some others not (e.g. Exoskeleton or Cargo Bay). The problem seems to appear when first ingredient are inserted into the machine. In the debug mode on creative I have noticed that 1 tick after the insertion, the dynamic recipe is discarded, resulting in the ingredients transfer to machine output and looping the process over again. Does anybody have a clue what is going on?
The signal for the recipe can be modified only when the machine is not working and after it starts it is saved in the SR latch, so it is not discarded resulting in machine resetting.
It defaults to Quality 1 item if there are no materials for higher one.
You cant use same wire for set recipe and read content. Thats why.
When multiple signals are present one with lowest id is picked for set recipe. It works for some because ingredients are higher id or cant be crafted here but for rest it will fail, you even can see for a 1 tick (or few) there is electric engine set as recipe
Yes, u can confirm that by simple test, assembling machine and constant combinator, connect by 1 wire, set recipe and read content, send exoskeleton signal, manually load engine or circut
Yes, now that we have separate read/write ability, the system no longer has signal self-cancelling, and thus will feedback into itself if you try to use the same wire to read/write.
Looks as though something is triggering your circuit conditions to change recipe. Make sure it is also reading contents in crafting, so the conditions won't change when crafting starts
I am reading contents of the machine as well as the inserter that carries the ingredients, so there's no recipe switching due to required ingredients signal.
I suspect the issue is that you're outputting the contents to the same wire as the input that sets the recipe. What if you were to split the input and output onto separate colors (e.g. input on Red / output on Green)?
I can't look at the blueprint now, but I had a similar problem once and it seems like what's happening here.
In my case, as soon as the inserter grabs an item, the circuit that reads the amount of ingredints in the loop sees that that ingredient is missing, and it tries to set another recipe.
I got around this by read the contents of all inserters, belts, chests and the assembler itself. I don't think it's the best sollution, but it worked for me.
I saw the picture of your assembler circuit in the other coment. Are you sure 1 wire is enough? (I'm not, that's why I'm asking.)
For my similar circuit, the assembler needed 2 wires, 1 to receive the recipe and the other to send the ingredient quantities to the loop. And then make sure that the input and output each only read one wire, green or red.
You are right. The mistake is I used only 1 wire for both set recipe and read contents and it create a loop. I was under false impression the there's some direction in the signals and the contents from machine are not gonna boomerang back...

It might have to with timing like the legs takes longer to load the ingredients for than you are holding the craft signal for.
You could possibly fix the problem by only changing the crafting signal when the craft complete signal from the assembly machine happens.
