I'm a first time user of MatterControl and I'm using v1.6 on Mac OSX on a Core i7 iMac with 8GB RAM. When I first got started, the app took several minutes to start up the first time I ran it, but now it starts up immediately (I didn't do anything to cause this change in behavior).

Now, during printing, about every 1-2 minutes the printer pauses for about 1,500ms and then continues. This ends up leaving small blobs of filament sprinkled throughout out the print. I was formerly using Cura and did not encounter this issue, so I don't think it's a printer problem per se.

I'm running a PrintrBot Simple Metal over USB (/dev/tty.usbmodemFA14311) at 250,000 BAUD (auto-detected).

Is there anything I can do to remedy the pausing behavior?

Many thanks!
