Note: This printer is pretty much the same as the Creativity Elf (AliExpress), so if you are searching for any details about this printer, searching for the Elf might be useful as well. I think there might be slight differences though. The frame is a different color, and the Coreception comes with LED lighting, which the ELF doesn’t appear to have.
So Amazon has the Sainsmart Coreception for $100 off (I just created a subReddit for it). And since I’ve been looking for a larger CoreXY printer to replace/compliment my Ender 5, I decided to buy it. And while I wait for it to arrive, I wanted to figure out if there was a better way to directly upload my timelapses to YouTube. My old method, stopped working. And since it was a little complicated I figured I would create a better solution that would be more reliable.
After a few months of owing my first 3D printer, I wrote a blog post talking about things that I wish I knew when I first got it. It’s now a year later, and I’ve learned a lot since then, so I figured I would share that.
Set your expectations on quality
So I’m seeing a lot of posts on Reddit and other places about people wanting to compile Marlin and having a tough time with, or more commonly, many people just aren’t doing it because it seems intimidating. I’m hoping to put together a walkthrough that simplifies the process as much as possible for people that aren’t really comfortable compiling something. Many people think you need to be a programmer to do it. You don’t.
So if you are looking for a webcam right now (I am writing this article during the COVID-19 pandemic), then you might discover that you are literally going to spend about 3 times the normal price. The Logitech C920 costs $200 right now, and the popular budget C270 will cost you $100.
You can currently get popular WiFi WyzeCam for around $25. And even the pan/tilt version for $35. However, those cams are WiFi only, and won't work out the box with your computer as a webcam for video conferencing(or for OctoPrint, which is what I plan on using it for). However, Wyze recently released a special firmware that allows that function.
For a few months now, I've been looking for a way to upload videos from OctoPrint (This link is to my previous write-up on OctoPrint and its plugins. Please check it out.) to YouTube automatically. I was optimistic when I learned about the OctoPrint-Dropbox-Timelapse plugin, and Zapier, I was optimistic that they would be able to do what I wanted. However, I was not able to get it working. But the OctoPrint-Dropbox plugin had a recent update, and all of a sudden, it all just started working. So I figured there might be others that wanted this, so i did a write-up on it.
About 8 months ago I purchased a Creality Ender 5. I wrote a mini getting started guide about it. In that guide, I mentioned OctoPrint, and how I would do a separate write-up on that. I installed OctoPrint after a few prints. I wanted to be able to monitor the prints remotely since the printer is down in the basement. This write-up goes through my setup and settings along with the plugins I used.
I was recently messing around with my Infrared Thermometer to make sure the air coming out of the heating vents was the right temperature. While doing that, I of course had to point it at random things throughout the house, when I finally got to the 3D printer, which was currently running. I figured that would be a good way to verify that the reading on the sensors was close to the IR thermometer. And it was close enough. The glass bed was reading a few degrees cooler, but I figured that was to be expected since the printer sensor is not on top of the glass where I was taking my reading.
As I talked about in my last post about the FilaWeigher, I wanted to add MQTT and temperature/humidity(Using the BME280) to that project. Well, I've done that. Refer to the previous post for more details. But now for this one, I'm just going to focus on the updated code and schematics, and the Home Assistant integration via MQTT. I'm going to leave the old post up for the people that don't want MQTT or the BME280 sensor. This version also has JSON output of all the sensors which allows for OctoPrint integration(I actually just finished up that plugin and I'm going to be posting that up soon).
I created this project so I can know exactly how much filament is left on a spool for my 3D printer, an Ender 5 I wrote about previously. However, it can very well be used to weigh anything else. I put a few settings that are specific to the filament, but they don't have to be used.
