first of all here is my setup:
SimuCUBE based OSW kit Biss-C - with Acrylic case
ServoMotor: MiGE 130ST-M10010 Biss-C - 4,2 mil cpr
PSU: Mean Well 480W (Noiseless) 20-30Nm
Servo drive: Ioni Pro HC (25A)
Servo Cables: Black MiGE Fully shielded cables with CNC machined connector
SimuCUBE Firmware, Configuration Tool and IONI Drive Firmware version all up to date to latest version.
I tried to setup the OSW today and went into an issue. I followed the starting and quick start guide provided by SimRacingBay for the OSW. Everything worked fine, until I tested the wheel the first time. There is a weird feeling with the wheel turning it around.
I try to describe it like it has different areas of resistance, – high resistance - low resistance - high resistance - low resistance – when I move around the wheel. I made a video which hopefully describes the issue: https://www.youtube.com/watch?v=MYoPLdl83wI
I also tried everything from different .cpr settings, older/newer simucube SW, checked proper fixation on shaft, configuring over granity SW, and even on different computer. The issue stayed the same. I also went through every single setting and the diagnostic information in granity (also together with people that have the same setup as me).
We have a guess that it might be the encoder, although the diagnostic data and settings are all fine in Granity.
I hope someone from the Granity can maybe help me and maybe this is a known issue.
Thank you very much in advance!
