I do have a lot of mods so that could be why it's not working. Do you know of anything that would prevent the system from working at all?

Perhaps my finding will help you: If you installed this mod >after< "advanced electronics" researched, the tab of this mod does not show up. :(
I had a problem with it too, so I tried to install at an early save, >before< "advanced electronics" researched - the mod then worked, as it should.
So try it on new game.

That is not the issue, the issue is that the circuits literally don't work. I have access to them, THEY JUST DON'T WORK

can you post a screenshot of your controller + blueprint ?

Unfortunately no because I moved on from that, but I can give you a modlist of what I'm currently using. Including your programmable controllers which still don't work...

I am betting it is a mod conflict or something, but I wouldn't be able to tell right off the bat. Give me a few minutes and I'll get you the modlist.

I don't think this is a conflict, the mod is very precise and should not works only if the controller's entities are replaced by another entity that looks the same, as I know if that the case, the mod responsible for this should be removed because it's bad practice and would break nearly anything.

put a power power supply next to a processor and paste and save that code

0000 YLD# 28
0001 JMP# 8
0002 V:signal-blue 0
0003 NOP# 0
0004 NOP# 0
0005 NOP# 0
0006 NOP# 0
0007 SLP# 3600
0008 YLD# 60
0009 YLD# 1
0010 SLP# 60
0011 INC@ 2
0012 SGE# 60
0013 JMP# 9
0014 MUL# 0
0015 JMP# 3

then press Reset then Start, the green bar should empty then be half filled then filled, if that works then the mod works

The problem is that I don't even see the reset or the start buttons

Edit: In fact, NO gui pops up when I interact with the controllers at all. The normal combinator GUI pops up but nothing else.

On which version are you ?

At the time that this was posted, latest unstable.

It might be easier to contact me through Discord. Famous5000#8968. That way we can potentially resolve whatever's causing this issue.

Yeah, no mod is interacting with the items themselves, and the buildings aren't touched either, it's just the GUI code.

This is an issue that the developer is actively fixing at the moment, it will be fixed in the next release, which may be in a few days.
