Thank Dave Touretzky of Carnegie Mellon for this find....
If you were sent a test print file by support, called PLA_GA_.CUBE3 or ABS_GAP.CUBE3 and neither the Cubify Client nor the Cube 3 would recognize it as a valid file. all you have to do is rename the file to change the upper case "CUBE" to a lower case 'cube'.
I ran into it right away. But, I don't have a PhD like Dr. Touretzky. So, I just shrugged my shoulders and abandoned trying to print it. LOL!
This confirms the wisdom of one of the principles I have followed for years.. "Always hang around with people that are smarter than you!"
Trust me. It pays. Dr. Touretzky just proved it. :)
Thanks, Dr. Touretzky. But, one has to wonder how 3D Systems got it to work.... hmmmm.
Now that I was able to print the gap test object, it confirms to me that the issues we are having with clogs are simply filament based. I printed the test print in black PLA and the results were beautiful This is the very same gap I was using when I clogged 3 different cartridges That, in an odd way, is good news in two ways. First, that my gap is now correctly set and secondly that I can expect the new filament to work just fine to put the clogging issues behind us.
