It's a shame about the work you've done if the desired goes so far but the positioning accuracy is not givenUnfortunately , the accuracy by stopping is bad , overshooting the position ...
The inaccuracy is with the gearbox modification as I understand it.
At 270° you still get 11 LNB's. I have taken the division 132-108-72-36-0-24-48-72-96-120-136 as an example, which can of course be adapted to individual needs.
Die Ungenauigkeit ist mit der Getriebemodifizierung, wie ich das verstanden habe.
Bei 270° kommt man aber immerhin schon auf 11 LNB's. Ich habe hier als Beispiel die Teilung 132-108-72-36-0-24-48-72-96-120-136 angenommen, die man natürlich individuellen Bedürfnissen anpassen kann.
No that wheel is original .is the metal gear wheel original?
did TRUST make it?
Ah, slightly different to how I remembered it.A bit late in, but from memory the Dark Motor devices I have here (based on the serial numbers they are from 2011), have no mechanical limit adjustments, the switches are locked into the casing at approximately 85 - 90 degrees from zero. The main cogs and gearbox components are all metal (with substantial bearings top and bottom) . The main wheel is toothed to approximately 270 degrees meaning removal of the limiting microswitches should provide a reasonable range for multi LNB work in the Trust endpoint design.
Though I've got other plans for my boom arm(s).
I will strip one down later to verify the above is correct.
I installed a pulse divider board in my SG-2500A. It contains a CMOS divider IC 4040 and has a divider ratio of 4:1, i.e. the pulses counted by the Hall sensor are divided by four and only then transferred to the motor circuit board for evaluation. This means that you can give a Diseqc motor more travel without a lot of effort, provided the gear wheel has enough teeth. For testing, I approached and saved three positions with the JPC-Posi, all saved positions are approached cleanly, repeatedly and precisely, just great
Ps: The limit switch positions still have to be redone in order not to drive into the gear gap
