Fix wobbling with code

[makssamedov36 0]

Hi. I have a self-made 3d printer. And because I designed it myself it has some problems with Z-axis. Wobbling is observed during printing. And yes, I know that I should fix my Z-axis (add a guide shaft, as the screws are not as accurate) but I detected that the wave is similar to sinusoid with ~1mm amplitude. So I want to programmatically solve the problem. Does anyone know how I can do it?

I use Cura slicer and it would be nice to find a solution for it.

This sounds familiar.  I think it was on this forum and someone was discussing a software fix.  I recall it involved anticipating sympathetic frequencies and avoiding movement that generated those frequencies in order to keep a printer from dancing to the beat.  A search around here might turn something up.

 

As for myself, all I know about sinusoid problems is to keep a box of tissues handy.
