afterPrintCancelled Script not running on Creator Pro

[HakuG]

For some reason, I'm not able to get the afterPrintCancelled script to run on the Creator Pro. This is a problem, as it can leave the nozzle to clog unless done manually. Any advice?

Hmmm... This indicates that GPX sent the "cancel" to the printer, which is actually a reset. GPX wasn't able to reconnect with the printer after the reset and so sent a Timeout to OctoPrint which fails the print. OctoPrint doesn't send the afterPrintCancelled because it sees a failure, not a cancel. I wonder why your printer takes longer to respond after a reset than mine...
