Sure, you’d need a fan for the generated heat, but the CM4 has built in WiFi now. I’m currently doing research into retraining one of Google’s models to do onboard failure detection of prints with a belt 3D printer, being able to detect a failure and then advancing the Z axis to try again from scratch would be a game changing capability. Not only does this allow the CM4 to be used in place of a lower-spec CM3+ module, it also comes with a Coral Edge TPU that can accelerate TensorFlow Lite models. I understand that to an extent, but I would still buy a printer motherboard with it now for one simple reason: Gumstix came out with a CM4 UpRev AI board. Posted in 3d Printer hacks, Raspberry Pi Tagged 3d printing, Creality, Octoprint Post navigation That’s a very different approach to using the Pi with a printer, but it does have some advantages. If you really want to have fun with a Raspberry Pi and a 3D printer, consider Klipper. We also like that there are many plugins for it, something that is not likely to happen with a closed-source box like the Creality. We like Octoprint (and the similar Repetier Server). We do wish had opened the thing up for us. But it remains to be seen if either of those things will happen, much less both of them. On the other hand, if Creality fixes the problems and expands the 3D model library, we’d buy one. You still need an SD card and a power supply, so those extras are a wash. But it is hard to see how this would be a better value than Octoprint unless you were very short on cash and had no Raspberry Pi surplus laying around. We have to admit, an attractive network interface for $20 would be of interest. Worse, the slicer didn’t really produce stellar results. The 3D model library wasn’t very comprehensive, although that could change if the thing got very popular. The box was pretty picky about connecting to printers and there were many other problems. In addition, the box integrates with a Thingiverse-like library and does cloud slicing, which is attractive when you have a very small computer connected to your printer. A Raspberry Pi with a similar case would be at least twice that price. You can buy the Creality box for about $20. You might wonder why you’d want this system when Octoprint exists? Mainly, the value proposition is the price. noticed that Creality now has an inexpensive WiFi interface that promises to replace Octoprint and decided to give it a quick review. Remember to change TH-intro.mov to match the name of your video.A very common hack to a 3D printer is to connect a Raspberry Pi to your printer and then load Octoprint or a similar program and send your files to the printer via the network. The added & is an instruction to run the command in the background. The first is a comment, to explain what we are doing, the second uses the command line video player omxplayer to play the video in the home directory. Scroll to the line before exit 0 and enter two lines of code. Open a Terminal and open the rc.local file for editing. Insert the USB flash drive into your Raspberry Pi and copy your video to the home directory /home/pi/Ĥ. Copy the file to a USB flash drive, we called the file TH-intro.mov.ģ. Your video should be 1920 x 1080 and be output as an mov file using the H264 codec.Ģ. #Raspberry pi zero w repetier server freeWe chose to use DaVinci Resolve because it is free and exceptionally powerful but any editor is fine. For best results why not have a boot splash image and a video, by doing this we keep all of the console logs hidden from prying eyes, and it keeps our boot process on brand.ġ. The process to add a video is also just two lines of code, and a video file. A picture is worth a thousand words and it can really sell your project, so a video must be an order of magnitude more effective.
