Technobeam Pan / Tilt Accuracy Issues

I know this is now a Strong product, but I am hoping some HES users or staff may still have some help with this.

We have several Technobeams in a rig exhibiting some positional accuracy issues. Others are fine. Most of the problem units seem to have problems with the Pan accuracy.

Once they are powered up or homed, they do not home to the same spot each time. If you grab them and manually move them to their limits you'll see them step back a "cog" or "notch." Some of them will be fine after that. You just have to run them to their limits before using them.

Other fixtures seem to home a step or two off and even after running them to their limits it seems that they home to different spots about 50% of the time. We have done hub set-ups on them and the motors don't feel steppy. Basically have to keep rehoming them until they hit their mark or you end up editing their position every day.

Wondering if anyone has some suggestions to improve their accuracy. Thanks.

  • While I can't say that I have worked on Technos, I had a Cyber that was losing home due to the brake on the pan motor being too loose. The fixture would run the mirror to the stop, and then apparently drive drops to the motor momentarily, and it would fall back a bit, and then repeat, never actually staying stopped at the homing stop.

    If the Techno has motor brakes on pan, you might want to check and see if the mirror will stay on the homing stop without power . . . there is a chance it could be doing the same thing . . .
