[QUOTE="harm lok, post: 1089297, member: 415123"] Again a lot off thanks for the suggestions and help. I have calculated the relation between the degree position and the extension of the actuator. If someone has a schematic off by Moteck V-BOX II then i would modify this to make the pulses accessable for a little microcontroller with a dish degrees display. Maybe i can put it together in one box. The algorithm is not that complex. But you can see it is far from lineair. Also the ( in my case with actuator mounted at left side ) the east side has a higher resolution then the west. Part off the original channelmaster design for good reslolution at east / west regions. I have uploaded the diagram and the calculation. I have made a adjustable table for every individual situation . If someone wanted that file please send me a personal mail .It is not possible to upload the excel file to this forum. After measuring the actuator length at the limits and also at 0 degrees it is a pièce of cake. [ATTACH type="full"]130589[/ATTACH] [ATTACH type="full"]130591[/ATTACH] [/QUOTE]
