Hello everyone, I recently bought a Braccio++ for a demo that I have to do at work.
I broke The Servo Horns (in truth they broke by themselves, but I do not want to make unnecessary controversy), I contacted support some time ago, but it seems a mission impossible to get help with this.
leaving out this unpleasant introduction (I'm an Arduino fan anyway) I am sure that this will be resolved soon.
When the Servo Horns (SR418D connected to the base of arm) was moving from 90° to 120°. It's broke about at the middle. I changed the servo horns and then My Servo 0 point is it not at 90°, but at 100-110. it seems that its starting point is no longer the correct one, but the one it was in when it broke. I run 2 tools: Test_Motor_Angular_Control and Factory_Set_Initial_Servo_Position without success.
What steps can I try to solve my problem?
Define what broke indicates. Is it an electrical or mechanical failure? If electrical what are the symptoms. Also if electrical can you post a schematic, not a frizzy picture.
the breaking of Servo Horns is certainly mechanical.
there were spare parts in the box, so I guess it's normal for them to break.
What I don't understand is what should I do once one is broken. how does the servant recognize his "0" point? do I have to do anything special once I have replaced the broken part? When the kit arrived, the orange parts were already mounted on the servos.
Well you need to fee the servo with a pulse length that indicates mid-range. IIRC this would be 1.5ms, but it might be different for your servos. That would make them move to their mid-point. Then you fit the horns so that the linkages they connect to are at the corresponding position, but I don't know anything about that particular machine. It should be easy enough to work out though.
