At rest (learn mode ON) the gearhead servo is 81 degrees Fahrenheit . Running a sequence which uses base, shoulder and elbow lift (but no elbow rotation) for 2 minutes raises the gearhead servo to 104 degrees Fahrenheit. The shoulder rises only to 97 and the elbow to only 90.Edouard RenardKeymasterSeptember 26, 2018 at 4:49 pmPost count: 239
To avoid confusion: The degrees shown in the Niryo One Studio > hardware status tab are in °Celsius. Did you convert the values to °Fahrenheit or you used the raw values that you read ?
I prefer to be sure we speak about the same thing before continuing the discussion.
Also, can you confirm that the fans on the back of the motors are all working well ?

I am using a thermal camera and measuring the hottest visible point on each stepper motor.
The displayed values are in Fahrenheit.
The fans on the stepper motors all run as soon as Learn_Mode is OFF.
All fans stop when Learn_Mode is ON (though maybe they should continue to run until units are cooled down).Edouard RenardKeymasterSeptember 28, 2018 at 3:52 pmPost count: 239
Thanks for the precision!
104°F corresponds to 40°C. 40°C is a normal value for this motor and it’s far from the limit value. Note that if a motor becomes too hot, it will not work correctly but won’t be damaged, you’ll just have to wait until it cools down.
Also, yes all the motors do not have equal heat, so that’s normal too.
About your last point: indeed it could be interesting to power on the fan with a condition on temperature. This could help the motor cool down faster when learning mode is activated. We’ll look into that to see if we add this functionality with the next software version !
