I’m a teacher in a new school and I rooted out an old MakerBot Replicator with original lazer cut wooden frame.
I installed software from Makerbot but when I try to print from Makerbot Desktop it gets to 54% then says that the prit failed
I installed MakerBot Print, also, and when I stop desktop running in the backgroup MakerBot Print still cannot from the printer as a printer in the options.
Did you install the newest version of Makerbot Desktop? I have a Rep 2 that performs just fine with the software it came with, but notsomuch with the newest version. Have you tried different models to print?
P.S. I have about 4400hrs on my machine and 90% of that time is printing via USB, not the SD card.
Try printing from the SD card and make sure to update the firmware on the printer. I have three of the original Makerbots and they have been the most reliable workhorses I own. But when I started out on my first one I learned quickly that many things going on with the computer can mess up a print via USB. Now I have nearly 6000 hours on my first printer and almost all of that minus a few hours was via the SD card with no issue.
