Abother day, another 3D printed bottle opener. Today was to see if printing directly from the SD card eliminated the freezes in the prints I have been experiencing the last two days when running the code from my laptop. First, the SD card reader on my MacBook Pro seemed to only read the card as read-only. Google to the rescue. The fix was to set the slide tab on the side of the card directly in the middle and give the card a little jiggle once inserted. Worked like a charm once I got it exactly centered. After that I was able to read/write but now I was having problems with the printer seeing the new file I added. A search on the Monoprice Facebook user group resulted in a reformatted of the card to FAT. Loaded the program again, the printer worked fine. So running the same program as yesterday but running solely on the SD card (computer not connected at all) resulted in a great print with no freezes.
