My printer does not use the WAIT command. Each time I load an obect, I have to go to the FFF properties, click the communications tab, and uncheck the WAIT command.
Is there a setting that disables this checkbox or set it to "off"?
That probably means your processes are overriding the firmware configuration. Basically, just watch the video below and it explains everything: https://www.youtube.com/watch?v=NYPUAqT4UyI
