Describe your issue:
Hello everyone!
I think I found the reason why my printers turn off.
Missed scheduling of next digital out event This is generally indicative of an intermittent communication failure between micro-controller and host.
I will briefly describe the process. Forgive me if I make mistakes, I am writing from Russian to English in a translator.
Previously, I had communication errors and my printer with the SKR 1.3. mini board and clipper turned off with a red communication error. I tried three microcomputers: the original pi, orange pi and btt 1.2. I eventually solved this problem by lowering the speed from 250,000 to 115,200 baud. Then everything worked fine until I decided to take the electronics of my printers out of the case to heat the chamber to 70 degrees. Then the yellow error Missed scheduling of next digital appeared. I tried many things: I lowered the baud rate to 2400 baud and even bought a USB with double insulation and ferrite rings, but then I noticed that this happens when I turn on the table heating. The table wire was extended with terminals in a plastic case. I threw out the terminals and soldered this place. The problem went away completely. I hope this will be useful to someone! Check your wires))
