Print acceleration VS travel acceleration


Recommended Posts

Posted (edited) · Print acceleration VS travel acceleration

Hello,

To improve Repetier Server configuration, looking for the difference between "Print acceleration" and "Travel acceleration". Firmware information does not indicate that.

And also the value of "move buffer size"

    Print acceleration; What is the acceleration to use while actually printing (eg; extruding material & moving)

    travel acceleration; what is the acceleration to use when moving (Moving head / bed & not extruding)

    Move buffer size has to do with how many moves the firmware should keep in it's memory. More is theoretically better, but most chipsets can't handle large amounts.
