VC3.1 300 Belt Tension Help
Hi all, I am working on retuning my vcore 3.1 after it sat neglected for a while. I did input shaper and noticed my y-axis is pretty bad. I also checked my belt tension, and know they're supposed to line up, but I'm actually not quite sure how to read the graph so I know what to adjust. Any insight would be appreciated.

While searching for info on input shaping and belt tension, I found some info about making sure that none of the hotend wiring was loose, and so I went around and zip-tied what I could and got an updated belt tension graph. I don't know if it's better, but the spike at 125hz is much lower.

Im not familiar with non-idex, and neither a core 3.1. so take my advice with a lot of grains of salt 😅
Higher tension generally increases frequency and amplitude, but it can do one or the other.
Try tensioning your upper belt a bit to see its effect on the graphs?
Fair enough, I'll give that a try. Thank you!
