Hello I have an ANYCUBIC I3 Mega, When I start a print the bed and nozzle heat up fine. The print starts last 1 to 3 seconds and stops. i have tried 5 prints, 3 which have printed before and 2 SD cards. Can you please assist in the trouble shooting?
I know it sounds silly, but have you checked the source voltage?
WOW!!! I have the same problem!
I did the following without good results:
I am doing prints without heating the bed, using painters tape... it works, but not happy about it
can you print via usb? - could try that to elliminate the SD reader?
May be a thermal protection problem.
