Hi all, total newb here. Just hooked up an ODS1 to a Flipsky 7070 v2 110kv. This motor has 7 pole pairs and I seem to have gotten the wiring correct and the motor passes calibration without errors. Running it off of a 24v 600W Meanwell power supply.
But, it runs pretty rough, at low speeds there’s significant cogging and at higher speeds there’s a pretty loud rumble that I guess is also cogging? It’s a bit strange in that the cogging feels like a “heart beat” i.e. as it’s rotating there’s a duh-duh … duh-duh … almost like just two of the poles are binding or something. I’m running this with basically no load at this time, it’s spinning a little fan to have something to look at.
Per the docs, I messed around with the vel_gain and vel_integrator_gain and it’s not clear there were any better settings than the defaults, although there are definitely worse settings 
I noticed that there is an “experimental” anti-cogging routine but it’s not clear if I can run that from the web gui, is that possible or do I need to go for the local python app? It was listed as experimental at least several years ago, has this been improved at all or even is it already included in the calibration? Have people had good luck with this and a similar type of high current motor?
Is this just an unsuitable motor and I get a pancake one instead? I was hoping that this thing would be virtually silent, but that’s definitely not the case. I’m building an audio device that will run inside of the house during quiet times, so really want to do whatever necessary to get smooth velocity control with reasonable torque and RPMs around 2000.
Thanks for any insight or pointers.
