Did anyone else have issues with their servo?? Our elevation servo seemed to have broken during the shipment process. We are currently trying to order a new one or possibly find a spare one.

Specifically, the servo is making a high pitch winding sound and does not have the strength to move around the ground station dish.

Usually the whining noise is the servo is under a load or not enough voltage. Those servos are pretty sturdy and would take a lot to damage it during shipping. I would make sure the voltage at the servo power it at least 5v and there is no binding or something out of alignment first.

After some analysis the maestro is still providing 6.3 volts to the servo. However it is still making that high pitch sound when nothing is on it.

Our servo made a high pitched whine for a couple hours of use, then seems to have burned out. One of our team members is pretty knowledgeable about RC servos in general, and he believes this particular servo may be overloaded by the weight of the dish. We're exploring the idea of replacing it with a stronger servo, but haven't settled on a model yet. We'll update if/when we move forward with that.

I tested the servo and it acts as it should be manually and when I try to run it via the tracker it has a problem tracking. Any ideas on what this might be? I am thinking it might be something in the code

Hey Dakota,
Would you like to elaborate what you mean it has a problem tracking, does it not move enough, does it try to point a complete different or opposite direction. If you elaborate We might be able to help you on this. Dave and I have messed with the servos a bit and have noticed a few particular things. If your problem is something that we have ran across we could possibly have a solution already. Also this gives us possible senarios to watch for when testing out different methods on the servos.

Recently our altitude servo (BM-5485HB-180 Servo Gearbox) might have died on us; would like to see if anyone else has had a similar issue: We are able to send commands and move the azimuth servo using all the Maestro pinouts. The altitude servo does not move or make any noises when a command is sent. The activated pins on the Maestro get ~0.37V, and ~0.4V when a command is sent to the servo. This is with a direct wall connection and no extension chord. Both servos have ~20MOhm resistance, so I don't think the servo burned a circuit or anything. One possible scenario is our servo rotating more than 360 degrees when it was unpowered. I'd like to see if anyone has any troubleshooting recommendations or has come across this problem before we purchase a new servo and confirm it dead. Thanks! |

USC,
I'm not sure I'm fully understanding what troubleshooting you've done. When you say it works using the Maestro pinouts are you referring to the use of the Maestro Control Center or did you build a secondary system that uses the actual physical pinouts on the Maestro board? If it moves using the Maestro Control Center but not with the GUI can I have you double check the serial settings tab in the control center to make sure that USB Dual Port is selected?
Thanks,
Trevor

Thanks, Trevor Double checked; USB Dual Port is selected in Maestro Control Center. By pinouts, I mean I'm checking the voltage on the actual output pins on the Maestro chip for the servos (to which my original comment was in error, I double checked and am getting 6.25V to the activated (from Control Center) pins on the chip. |

Can you move the servo through the control center?

I can only move the azimuth server through the control center but can't move the altitude servo. To clarify, when I "send commands" to the servo, I'm attempting the move them through the control center.

Just to verify, both servos are connected to the Maestro board with the ground line on top?

If you swap the channels the two servos are connected to on the maestro are you still able to move the azimuth servo but not the elevation servo?
