The pad has a 7” 1024×600 resolution display but with all its ports it’s a fair bit larger than that at 222 x 130 x 40 mm (W x H x D). Corona discharges are partial discharges that occur in a gaseous medium. They are produced in highly inhomogeneous electric fields and are formed at lower voltages needed for a complete breakdown. I then ran the ringing test model that Klipper provides sliced at 80 mm/s, changing the acceleration every 5 mm starting at 1500 and finishing at 7500 mm/s². I did change the maximum acceleration in the printer.cfg from 5000 to 7500 mm/s² beforehand. You can see the results – pretty impressive with very little ghosting. Look at Klipper’s excellent documentation if you want to try this yourself.

Q27: Why does a prompt box pop up to prompt saving after printing is completed, after adjusting the Z-axis height during the printing process? Confirm that the camera is working properly after executing [Camera]application. Please follow the next steps if it is not.

Please go to the corresponding instruction based on the current Windows operating system on your computer: The most significant benefit of the sonic camera is that it can be used in daylight and is relatively simple to use in contrast to the DSLR camera, which requires total or partial darkness.

You can also make adjustments on the fly by tapping the Adjust icon. From there, you can change speed %, temperature, change Z height, flow, and fan speed.b. Some cameras are customized cameras, which are not output in YUV and Mjpeg formats. Try to replace the camera and use it again; But even without pushing it, using Creality’s normal PLA profile the printer is still usually around twice the speed it was before, with results that look at least as good as those printed far slower.

Corona discharge is challenging to detect in daylight because of the low level of visible radiation. High-voltage laboratories often use high-performance digital cameras to find corona discharges at night . Limitations of Sensors and Cameras Used to Detect Corona Discharges

Thanks to the high resolution of the screen, you can also connect a webcam to the Sonic Pad. At first glance, this sounds relatively pointless, since the pad is always close to the 3D printer, but you can then monitor the 3D print via the web interface. Muhr, M.; Schwarz, R. Experience with optical partial discharge detection. Mater. Sci. Pol. 2009, 27, 1139–1146. [ Google Scholar] The effectiveness of two cameras, an optical DSLR camera and a novel sonic camera that enables identifying and detecting the origins of corona discharges has been assessed and compared in this study. A large part of the 3D printing community is interested in upgrades or other improvements to their 3D printers. Therefore, it is no wonder that open source is very common. So that specialists can also let off steam creatively with the Sonic Pad, Creality has not put a stop to this and made the complete source code open source. Many Interfaces

Some cameras are customized cameras, which are not output in YUV and Mjpeg formats. Try to replace the camera and use it again;Printing with Klipper has improved this problem and generally increased the surface accuracy somewhat, but ringing has become much stronger. Klipper alone is not a miracle solution here. I was actually surprised by the result with the accelerometer. The ringing is extremely improved and the surface quality is as good as with a very slow print without Klipper. Add the function of "skipping self-test", saving time for those printers that are confirmed without issues and providing more choices.
