Before trying my own STL files I thought I'd get it to do a demo. It stopped and gave me a 0040 (cannot read\write SD card) error. XYZprinting said they'll reply to my support request within 3 days. 3 days!
Anyone know about this error?


And anyone know how I should reset the machine... It is flashing and beeping in the middle of a stopped print. How do I switch it off safely?

The site tells me to check the SD card, but no documents tell me how to get to the SD card.
