The same issue as in the printer counter script. You HAVE to have all the devices set in code. If you don't have some of the devices (i.e electronics printer or tool manufactory) you have to comment them and their sorters out of the code.
Script will try to keep a minimum of 50g of the corresponding ingots - steel, silicon. gold, iron, copper in the printers.
If vending machine runs out of some ingots, it will be stuck in a loop trying to supply them.
You can check code- ingots will be requested in order last-first. People get stuck at steel because steel goes before silicon, gold, copper and iron. If you have no steel in the vending machine, nothing will be deliverd at all.
You can connect hash console to the housing to display what ingot code is trying to supply right now.

which one? @NeoGP

I suggest going to his YT channel and finding the build there, starts around the 4-minute mark.. you can fast forward through the coding, some of the restock, eating drinking etc..
Thanks for a great code!

doesn't seem to resupply of anything but Steel even when I press the button

No matter what i try, it shows error on line 50- device not found.

@wizard1001 thank you for the information i will go look it up

@Garason, Mick has a video on YT of the full build if you can't wait for the world to be uploaded.

most likely after he finnished the serie, he might be uploading it

cool just been looking for a code like this is there any chance of haveing the world uploaded so we can see a working version i seem to always make some sort of mistake only seem to find when compareing
