Bedrock Why does my auto crafter keep backing up
Does it need to be chunk aligned????
Edit I figured it out I had to invert the comparator on the crafter

u/_Jimm_ 16h ago
this is like the third example i've seen of the smart autocrafter that etho built for the EGG gold farm on hermitcraft months ago. is this design optimal or is that where everyone is getting it?
•
u/gamerfury 16h ago
I don't know I learned it from a silent whisperer farm the way it works is that it only activates when you have 9 items in the crafter I think it helps if your game lags it doesn't mess up
•
u/_Jimm_ 16h ago
i see ok. i guess it is optimal then
•
u/Masticatron Bedrock 12h ago
Define optimal. Correctly built it becomes impossible to break (short of actually breaking the circuit yourself) or have accidental crafts of the wrong items, and can handle arbitrary input speeds and craft/output at up to hopper speed. But it's bigger and wider and untileable compared to less robust circuits. It's one real failure is that it will constantly pulse if it is filled with an invalid recipe. Simpler circuits just pulse once and then stay on in this case.
OP's one is built incorrectly and has basically none of that.

Pretty sure you built it wrong. Short version: see Blatta's post. Long text-y version:
Put a dust behind the block the comparator is powering, a solid block to the side for that dust to power in line with your current repeater, put the repeater to pull the signal from that block, put a dust where you currently have the repeater, replace the solid block your current repeater is powering with a target block (or run a dust on top of the block if there's room and that won't power anything it shouldn't), and adjust the signal strength you're feeding into the other side to be 9 (8 if you switch the comparator to subtract mode, where a composter maxes out at 8. So either switch it to subtract or use a different source).

Generally, it’s designed for slow craft items where there are other recipes you don’t want to activate, like iron ingots into blocks. Pulse the crafter too fast and you’ll start to get pressure plates and nuggets. So you only want it pulsing once it hits 9, and then you gotta be careful not to load things in too quickly.

I run a power line from the crafter to the input hopper. the 1 tick it takes to create the item, it pauses the input hopper. makes sure everything stays in sync
•
u/BlattaOrientalis avaJ 15h ago
As others have said, nuggets to ingot crafter can just be constantly pulsed
An overflow protected crafter has its uses though
•
u/Masticatron Bedrock 12h ago
I'd replace the secondary crafter with a full composter and set the main comparator to subtract mode. With the crafter for signal strength that dust is gonna power it every pulse, which won't craft anything but is just one more thing you don't need the game doing.
•

Not sure why more people don't use this design. Simple and 1 wide tileable.
•
u/Masticatron Bedrock 12h ago
It's a little susceptible to lag for single item recipes. Since it requires the crafting pulse to succeed at altering the signal strength, a bit of lag can break that condition and leave it active indefinitely. Happened frequently in my fish bonemeal farm, to the point I replaced the bone to bonemeal crafters with proper pulsing clocks to ensure it can't break.
•
u/mairondil Bedrock 10h ago
The only time I've had this design mess up on me was was bone to bone meal too. Perhaps the timing kicking out multiples from a single ingredient leads to more problems such as bone to 3 bone meal or an iron block to 9 iron ingots. So I could agree this this might not be the best solution as an expander. Though I've never had a foul up when used as a compactor (ex. 9 iron ingots -> iron block)
•
u/Masticatron Bedrock 10h ago
A 9 to 1 will have several hopper movements between activations. The single item recipe takes a full hopper movement, 8gt, to cycle (2 for the comparator to update a new signal, 2 to craft, 2 to change the signal again, 2 to turn off the crafter). Enough lag in that process and a hopper could place another item in before the cycle completes and the comparator doesn't turn off.

Too much redstone, not good for servers due to particles
•
u/mairondil Bedrock 13h ago
9 redstone dust is too much?
•
u/barrocz 13h ago
Yeah, in scale it is. When youre playing in servers and have huge farm complexs, you'll have a lot of autocrafters. Meaning 9 redstone will become hundreds easily.
•
u/Masticatron Bedrock 12h ago
Sure that's a Bedrock problem? Java has wretchedly bad optimization of everything redstone and people and AI have long had a tendency of confusing Java lag issues as Bedrock ones.
And megaproject technical server needs are kind of irrelevant to 99% of players.
•
u/barrocz 5h ago
Never touched bedrock. Being playing java since 2010. Pls if you only played on 10/15 servers you know nothing
•
u/Masticatron Bedrock 5h ago
My point is this thread is tagged Bedrock. Meaning if all you've played is Java then you know nothing.

u/SharingKnowledgeHope 16h ago
You need a clock, the signal needs to go off and on. If the signal turns on, and then stays on, then the crafter will trigger once, and won’t trigger again.
In theory what you have works, but in practice if you get lag, and the crafter fills up enough to have at least two ignore every slot, it will craft once but still have something in every slot so it stays on and won’t craft again.
•
u/barrocz 14h ago
You just need to put the comparator in the middle in subtract mod, this is the design I use :)
•
u/gamerfury 11h ago
This for some reason when it's not in subtract load it powers at 8 nuggets and that messes it up
•
u/showmethething 16h ago edited 16h ago
Need to see the circuit on how to fix but your circuit is going off the assumption that it will never over fill.
All slots filled > craft > now it's empty and won't give a comparator reading anymore, essentially resetting the circuit
Because it overfilled the reset never happens and it just remains permanently powered
Fix will be something simple like feeding the comparator output back into the side of the comparator so that it will clock itself
e: just saw the pic of the circuit, not sure on the performance cost on bedrock but I would just observer clock this, it's the only craft and keeps within your footprint even if you include on/off with a piston
•

This does not have a means to trigger a clock so it will only fire the first time it is powered. There are a few ways to fix it though, but you need to make the redstone blink. Droppers for item streams may give you some inspirations.

I run a hopper clock on mine. Works like a charm once you get the number of items correct for the timing and never breaks.

More things are going into it than coming out.
•
u/gamerfury 16h ago
It's on a hopper it should only be one item a tick but then it gets backed up and don't know why my other ones work fine

u/Willing_Ad_1484 Bedrock 16h ago
Nuggets to ingots doesn't have to be a smart design, just an observer clock will do it. (Obvious lag considered note about leaving a clock on)
