Printer stops on first or 2nd layers with this error. Anyone know the cause and fix? Only seems to happen when printing from SD card

Hi Lee,

The error is because of a miscommunication between the touch screen and the firmware on the printer.

Re-uploading the touch screen firmware should solve this:

Also, make sure that you're using a class 10 SD card, one should have been included with the kit, if not please email us at info@makertech3d.com

Hope this helps!

Think I’ve sorted it by re-formatting the SD card. I also made sure that Cura sliced and copied it direct to the SD card so to take out any randomness/corruption from the laptop in copying a file from one location to another
