Yo! Good to compare data, I tried logging my MakerX through Floaty but it won’t connect — what do you use to get data into Float View?

Good to hear your TC isn’t kicking in much. In my case the issue gets exaggerated when doing tight figure-8s on smooth concrete while going full throttle and shifting my weight back. On normal rough asphalt with equal pressure it’s barely noticeable. I only feel it sometimes when carving harder, where it can throw me slightly off balance. My stock SBX doesn’t do this at all. I’ve seen similar behaviour on another setup with FB-5X spring trucks. I think the issue was always there but is now worse due to the added flex and the center wheels lifting from the Otherboard trucks.

Because TC shows as “disabled” in VESC Tool on the stock SBX, I’m pretty sure there’s some custom ERPM-equalising logic running in their firmware :thinking: Also interesting: the SBX patent shows a scheme. If they’re using VESC-based firmware, I wonder how they implemented that.

Hey guys. I’m new here and kind of stupid when it comes to all this stuff. I have an sbx 2 and while it will connect to my remote, it wont respond to my inputs on the remote. When I connect it to the summerboard app and optimize motors, one motor buzzes loudly, then starts spinning up. Then the next motor shakes and buzzes much louder and sharper, then doesn’t spin at all. Again, no response from my Roomate even though it says it’s connected. What should I try to do? How can I take this thing apart to clean up the connections incase of debris? Why is there no info anywhere on the sbx 2, and why the heck does support stink?!
