Intermittent freezing mid-print. Firmware unresponsive.
I’ve been having an issue where the firmware on the Mega2560 board no longer responds to g-code commands and the machine freezes in place mid-print. Obviously this ruins the part I am printing and eventually led to the printer nozzle itself becoming blocked.
Once the machine is frozen, the only way to recover it is turn off it’s power, then unplug the usb lead, wait a moment then reconnect the usb lead, power on the printer and hit the “connect” button in the software.
Is there a watchdog or status on the Mega 2560 that can give me some kind of insight as to what is going wrong?
I am comfortable with changing the arduino code if anyone has a way of indicating status.
Any info would be welcome.
Is this a good question?
