Good call on the greased bearings….didn’t make a difference. We have sent one of the units to Michigan I believe to get looked at. Only response from that group was “This is a known S5 issue”….I will give an update when I have one, but boy is this a lot of run around for one of expensive robot.
I’m curious if there are any site specific conditions that could be causing the issue? I knew a surveyor who sorta had the same issue running traverse along a road. They too made a couple runs with different crews and equipment and nothing changed. Then there was an accident, all traffic was held up and they re-ran the traverse and ended up with a good loop.
The whole bearing grease thing seems off to be nice about it. No one ever clued us into greased bearing issues on our s5.
Gary…..It was different sites, different crews, and even different instruments and DC’s…..results were consistent. My first thought was the crews made a calibration change or an encoder ring failure. That even does not make sense as it is different guns. That Trimble noted it was something they know about is odd to me. From the years I spent in an electronics lab, I wonder if a flash chip has failed on the instrument, but that also seems unlikely as it is multiple units.

Would the shop run a check on the autolock collimation when it was brought in?.
The autolock collimation is individual to the prism being used. The shop couldn’t run such a collimation , meaningfully, without your prism.
Reading this out of interest/in case this problem ever comes up for us in the future……this made me wonder…most of my work is done with the MT1000 prism. When I do the collimation adjustments I have a standard round prism set up on a tripod. Should I be switching to the MT1000 just for the autolock collimation since that is what I use most, except when setting up a backsight (or doing a long traverse).
Thanks

You can easily collimate the tracker in the field. It’s astonishing that you don’t know of it and think a repair shop has to do it.
Field and shop calibrations have been run multiple times Robert. The prism thought Norman brought up is interesting but as far as I know, they all have been using the same prism for traversing and calibration (not sure what is happening in the shop).
