Hi so I've just finished wiring everything and my raspberry pi is giving a low voltage warning in octoprint. I've tried with an external USB plug (even using the same cable!) and it works fine, so I'm guessing it's something off with the included USB adaptor thingy.
I've got a 3B+ Pi, if that makes any difference.
I've not plugged in the camera or anything yet so that's not drawing any power from the pi (not sure if that'd even affect the voltage)
I tried checking the connections in the terminal block and they're all fine, taking them out and putting them back in made no difference.
Order this: https://www.amazon.com/MCIGICM-step-down-Converter-3-0-40V-1-5-35V/dp/B06XZ1DKF2 You just connect it to the 24v side, get your multimeter, and test the output while you turn the adjustment on the pot. You're looking for 5v. Then run the outputs from the converter to the GPIO 5v positive and ground pins.
same issue here, I can print via octoprint, but it is complaining about undervoltage on the Pi board.
edit: oh, rpi3b+ makes no difference, I installed the upgrade kit delivered Pi1, and it has the same issue.
I'm also having this problem
Edit: After plugging in the usb power cable directly into an outlet, I no longer have problems. I feel like this problem should've been addressed from a design perspective however.
Having the same issue as you! and i cannot print via wireless only via SD card
