Print acceleration VS travel acceleration

Recommended Posts

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.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
