Wheel goes hard/stiff after hitting ends #10

Open ba114 opened 2 years ago

ba114 commented 2 years ago

When i rotate the wheel in either direction after initially turning it on, it moves very easily until i reach rotation lock. As soon as i hit that point the turning goes incredibly hard no matter which way i rotate the wheel.

Setup is odrive 3.5, FN120N, 50W4R braking resistor, Omron E6B2CWZ6C 2000 PPR encoder.

What settings do you have in hardware tab?

OK all seems to be fixed. Setting a soft stop range to 10% had an effect initially, but trying different wiring combinations on the motor seems to have fixed it in the end.

With this setup, when you reach an end stop, it starts spinning uncontrollably: A - Green B - Blue C - Yellow

With the below setup the end stop works properly and all seems to be working well: A - Blue B - Green C - Yellow.

Is it with the last version of firmware? Issue with the wiring order was fixed at some moment and in the last version should be ok. If not, I will look into it.
