Smoothieboard printer hangs while printing

I'm using Repetier Server with a Smoothieboard printer. It works great with Repetier Host. When using Repetier Server, however, printing once in a while is interrupted by sudden stops, sometimes for a duration of a few minutes. The print finishs but the result is really bad, of course.
My connection settings are:

Ping-Pong: no
Buffer: 255 Byte
max parallel commands: unlimited
comm. timeout: 30

What can I do to improve this?

Thanks in advance



  • Are these the same buffer settings as in host? If 255 is more than smootheboard has, this will lead sooner or later to com errors. 127 is normally a safe bet. Also make sure to select smoothie firmware to ensure some smoothie special behaviours.
