Hi
I have a reprap rostock with a smoothieboard. It runs off of my computer not an lcd. My computer is a 4GB macbook pro.
I am having issues with it slowing down on longer prints. Sometimes it slows down at 3 hrs or it might take until 8 hrs in to slow down. When it slows down it continues to slow until it comes almost to a stop and starts glitching.
Sometimes i can pause the print for a minute and after resuming it will speed up for a few layers but then continue slowing down.
What do you think could be causing this?
Thanks
Tanner

Sounds like a USB buffering issue or something related to a power save mode in the computer.
Some people have the computer OS chops to know (or claim to) how to prevent every possible computer induced problem from occuring, but there's still that USB cable and the connectors at both ends, and that keyboard just waiting for a kid, spouse, or pet to touch the wrong key at the wrong time. You can become an expert in the OS and host software of your choice and try to fix all the potential problems, or do what some of us do and eliminate the computer completely by printing from SD cards plugged into the printer. I don't regret any of the time that I haven't spent debugging computer/host software problems in the last couple years.
Don't worry, even if you eliminate the computer/host software problems, you'll still have slicing, print bed adhesion, extruder, and filament problems to deal with.

Don't forget to get the adapter board for the smoothieboard with it.

It's quite possible to run a smoothieboard without an LCD, or having the computer there all the time:
Just copy the Gcode file onto the SD card, then using a terminal program (I'd use putty on a pc, don't know about macs) get talking to the smoothieboard and issue the play command.
This will make the smoothieboard print from your file, straight off the sd card and you can disconnect the computer while it is running.
