Describe your issue:
Hello Guys,
i had a recent Error while Printing my last Job. After somewhat 3 Hours into Printing the Print stopped and I got the error
“MCU ‘EBBCan’ shotdown: Scheduled digital out event will exceed max_duration”
From reading the docs (and what i understand) this means that there are too many scheduled jobs waiting to be fullfiled by a given pin.
My EBBCan 36 is configured to work over USB Connection instead of Canbus because i couldn’t for the love of good make it to work over can (tripple checked the wiring, measured everything with a multimeter, had the correct Ohms throughout my Canbus Network, tripple checked Jumpers and so on …but that is another story. For me it works over USB just perfect, so no need to change that).
Any Ideas what specifically caused this, how to avoid it or reconfigure something so the max_duration (if not determined by let’s say the EBB Can36’s CPU Clock(?)) doesn’t overflow?
Any help is appreciated. Thanks in advance
