Tuning my Hybrid belts is becoming quite the ordeal. Stock coreXY mzv Y acceleration is about 3700, adding y belts only takes it up to 4200, but the response is terrible. If I do tune the y belts to make an acceptable graph, the acceleration will still sit at around 4000, but the belts are just tightened with finger strength, nothing more. I tried tuning with the pinned macro isolating the y belts, but I can't tighten or loosen the belts to get the response to be anywhere close to matching.
first 3 added pics are during core xy. Last few pics are during hybrid calibration
