Hi dave,

Thank you for your prompt reply
I modified the script with your tip and at first worked just fine, here the group was exalted with the digital servo working as we wanted, but that was just the first movement we sent through the servo script.
Then the servo "lost" instruction, and did not maintain position and did not accepted any new instruction. And that was what happened from that time. Strange is that it worked fine the first time and then its like the registers are not working anymore or the output pins are reset or something, will use an oscilloscope to see the signals from the robostix.
By the way, what do you mean by speacial code for the digital servo?
thanks in advance
