Hi everyone, Sorry for the late response, but I have been extremely busy this last week (what else is new). And I will unfortunately have to put this project on hold due to various life related circumstances. So, I just wanted to thank you all for all your help and responses. As for what I end...

Sorry for the late reply, been quite busy for most of the week. But here we go... Ah. I see what you mean. Fair enough. Although, couldn't I use those as well to send signals to the relay board that you linked? That's kind of the point I was making though. Because then what happens if I...

And again, this is why human terminology sucks. I always thought the same way, that basically the hot end should be called the extruder, and whatever pushes the filament into the tube should be a "filament driver", since as you said, that would make sense outside of 3d printer contexts. But...

Here's the thing. My Pi is what talks to my 3d printer. It uses OctoPrint to send gcode to essentially tell the printer what to do when printing. That same Pi also controls a beefy relay switch, which is connected to the printer as well. Currently, when I contact my Pi through Wifi, I can click...

I'm a little bit confused by this statement. I agree the circuit is messy, but there is a signal coming from the pi. It would be coming from the GPIO pins. Although, as you point out later, and now I am realizing it myself, there needs to be a relay driver of some kind that receives that signal...

We need to be careful about terminology here. And I might be the one using it incorrectly, but to me, an extruder refers to the "filament driver" (not including the hot end). It's the motor that pushes filament into a tube that eventually goes into the hot-end (the thing that "prints" the...

No, no. Haha. Geez, am I that bad at explaining my thoughts? I am specifically NOT trying to do that. No reverse engineering - I want to leave that stuff alone. That's why instead of doing something like that, I just want to redirect whatever signals (and power) its sending through its 4 pin jst...

Uh, this would defeat the whole purpose. Essentially here's the big picture summary-- My 3d printer is a black box. I have no idea what signals and power it sends to the original extruder/ filament driver/ motor normally. Re-creating that would be a pain and super complex. So, because of that...

Finally had some free time, so I updated the diagram/ schematic. Here is how it looks like now: To clear up a few things, here are a few notes: - I'm still not sure if a relay driver is even needed in this case. So this schematic does not include it. - The 'B', 'A', 'V' (and GRND) pins are...

Oh, that makes so much more sense now that I think about it. Of course! - you're right. In my current relay setup (the non-DPDT), its a heavy duty relay that turns on when the PI sends a voltage, which in this case is a signal (which controls it, telling it to switch states). I completely forgot...

Uh, what? There's no l2C being used here (at least as far as I know). The PI comes with a Wifi module built in. The computer can already talk to the PI. At the moment, that current relay is not connected to the PI (I have yet to buy it), so it is not talking to any relays via a standard...

I'm a bit confused here. How would this help exactly? Maybe I misunderstood your comment about l2c being more commonly available than Wifi on relay boards). But, I specifically want to use Wifi. I want to sit on my lazy bum, from my computer on third floor, press a button on my computer screen...

I appreciate the enthusiasm, but this is not what I am looking for -- and it would ultimately lead me back to the same issue. The issue is not that I need to control something wirelessly; that's what my Raspberry Pi is for (I use the GPIO pins to drive things by contacting the PI's local server...

Hi, Thank you for responding back so quick. Apologies for not responding sooner, I have been very busy the last few days. This is exactly what I was looking for! However, I am trying to understand how it would work and what connections would be made specifically -- looking at the diagram...

Hi, First off, I want to say that I'm basically a noob when it comes to electrical engineering; I have some knowledge and took an intro to robotics course in college, but if I knew the answer to this question, then I wouldn't be here asking haha. So here it is: From what I know, relay...
