Firmware Unresponsive during print

[kyphur]

I started a new print tonight but I noticed it acting a little weird so I took a look at the communication in the MCP. I kept getting this in certain parts:

WARNING: Firmware unresponsive. Attempting to force continue...

Sometimes it took a while for it get an O.K. response.

What are normal causes for this? What is the usual fix for this if it continues?

are you printing via usb? i would print through sd card and reboot the rambo. double check that the baud rate is set correctly also.

Yeah, printing over USB. I rebooted it and it seems as if it's moving at normal speed. I'll give it a bit on this second attempt and see how it does.
