My new Lulzbot Taz 6 3D printers are not working properly.
When I insert the SD card that came with the printers, it is correctly reading/finding the pre-downloaded Lulzbot files that came with the machine.
When I save my own .stl files on the same SD card, the sd card reader is not finding my personal files. It only finds the pre-loaded Lulzbot files.
This is happening on all of my lulzbot taz 6 printers.
I tried using new SD cards with no luck.
Any help is appreciated as I am relying on using SD cards for my students to do their printing.
Thank you kindly.
