Upgraded the factory firmware on my Ender-3 to Marlin 22.214.171.124
now, it has started randomly pausing during printing for 1/2 to 2 seconds then continuing on. does it even on simple prints (20mm calibration cube) No error messages in the serial.log, no other errors I am seeing.
Found a post where someone resolved it by upping the baud rate in the marling configs. recompiled Marlin for 250000 baud. no change
Replaced USB cable with a short brand new cable, High quality, EMI suppressed etc. No change. Took the octopi from my Anet printer and hooked it to the ender, and it does the same thing. Pi's are Both Pi4B's this wasn't doing it before Marlin.
Printing the same gcode from the SD card and it isn't doing the random pauses.
I am seeing a lot of the following :
