Hey man!
I noticed between this thread and the other, that you wanted to go fast and were using 5.xx firmware.
Are you aware of the “Duty Cycle Current Limit Start” setting?
With 5.xx firmware from my understanding it defaults the “Duty Cycle Current Limit Start” to 100%.
Reason why this is an issue is because when you hit the boards top speed (100% duty cycle), it will instantly stop accelerating, which will throw you off.
If anyone could correct me if I am wrong, but it seems like the general consensus is that setting the “Duty Cycle Current Limit Start” to 85% allows for a safe buffer.
Just please make sure you change “Duty Cycle Current Limit Start”, as there are other settings with similar names, but changing these will not solve the issue.
