slipshine - these are good suggestions. I'll see what I can do to get them implemented. I know we've tried different methods for making sure the print won't pause while doing other things, but we had some issues finding a good solution that worked on all operating systems. So yes, you can still do other tasks while a print is running, but if it is a task that takes 4 or 5 seconds (like browsing for a file or maybe slicing a very complex part), it might temporarily pause the print until it completes. A few suggestions until we get a better method in place: 1) If you want to import a file, you can always just drag and drop it onto the virtual build table. 2) As you noted, printing from the SD card also fixes this issue and is generally recommended.
Dale - We've done this before without issues. We usually just disconnect and the machine keeps running. With the M2 you can tell if it restarts just by listening to the case fans. Try connecting (you'll hear the fans spin up), then click Disconnect (the fans should stay spinning). I tried this on a few of our computers and they all work fine. Does anyone else notice the same symptoms?
