Interpolation not working?



  • Here is a video with interpolation for XY on

    and here is it switched off

    I'll be honest, I can't tell much difference in terms of noise or motion. Is it not always obvious the affect interpolation has?

    The effect of turning interpolation on/off varies with speed. On my delta it makes a lot of difference during printing, but much less during homing.



  • I can't see the difference… Someone hace a printed object with /without interpolation?

    dc42... In what kind of prints it's more useful interpolation? And when it's no recomendable his use? What drawbacks have?


  • administrators

    The main benefit of interpolation from x16 to x256 microstepping is that it makes the printer much quieter. I don't expect it to affect print quality at all.



  • I can quite happily confirm that whilst for the last 18 months or so (has it been that long?) I've used 1/16th interpolated for all axes, I did have a period recently of using 1/4 for extruder which turns off interpolation for XYZ. It was a lot noisier but printed exactly the same.
