Questions regarding acceleration.

[daftscience]

So the EEPROM of the Repetier firmware has settings for acceleration. Is that a max value or the value for every change in direction? I know that KISSlicer lets you set the acceleration when you're slicing so does this EEPROM value over ride it?

And finally, if I increase the multiplier will it also increase the acceleration (I'm assuming it does) or will it stay below the value in the EEPROM?

Thanks in advance.

I do not know for sure, but my assumption has always been that the firmware setting is an absolute max and the slicer setting is what is written into that specific print's gcode. In other words, I think the slicer setting is what it uses as long as it's under the "speed limit" set in the firmware.

The Kisslicer accelleration setting is only used to estimate the total runtime of the print, it has no effect on the actual GCode generated.
The EEPROM value is is used.
For speed that's different, the speed specified in the slicer is what get's output in the GCode, however the actual speed is dictated by the firmware, by JERK, ACCELERATION and MAX_SPEED setting, and in many cases will be lower than the requested speed. This is especially true if the moves are short or require a significant change of direction at either end.

Answers my questions perfectly. I was really concerned that increasing the print multiplier would also increase the acceleration.

Have you adjusted those eeprom values much? I believe my acceleration is set to 800mm/s^2. At that rate there are some pretty harsh movements when doing a solid infill on narrow spaces.
