Simucube 1 - possible failure

Hi
I use my simucube with iRacing, i have been away and not used my rig for 3 weeks, i turned it on and it was not seeing my wheel in iRacing, i’ve reseated cables, down loaded the configuration tool, updated firmware and tried everything i can thing of …
My wheel has a very “lumpy” feel when not running software, the configuration tool software reports
Operating Mode: waiting for drive to get ready and thinks the E-stop is pressed (it is not), if i move the wheel it then shows as disconnected fr a short period.
any ideas what i should try next ??
thanks
Richard

What error codes does Granity present?

yeah, click “enable IONI Configuration” and then connect with Granity to see servo drive status. It might be broken e-stop button or wiring. If Granity shows STO active, then thats what it is.
