I have done several testing myself also and broke my door...They give way too much torque, so you need to have a perfect mechanical set-up without any binding at the beginning and end of stroke....

I sent an email to Peter at altecare about the problem a couple week ago, he was supposed to as Lado what they can do...i did not got a reply back yet....They really need a programmable torque limit, but i think, encoder is the only ''safe'' way....

By the time, i'm planning to go with firgelli only, with thoose units, you can adjust both stroke end the way you want, exactly the same as it was a servo....
