Input Buffer Size

I have a Ender 3 Pro and a CR10s both with SKR mini e3 v1.2 boards running Repetier Server independent from each other each on a Raspberry Pi 4 (4GB) with 64GB EVO High Speed SD cards.. what is the best Input Buffer Size to use with them ??


  • Best value is size of buffer of printers. That is normally 127 byte which is what 98% of printers have as limit. If you get resend requests or a lot of errors you know you have exceeded the firmware buffer size. Much more then 127 does not improve much any way. Only the second and third parallel command send improves speed.
