I’ve been troubleshooting polar alignment drift on my iOptron HAE43B‑EC and may have found the culprit. The altitude axis clamp requires very high torque to hold alignment — I have to use the included wrench to really crank it down, otherwise there’s noticeable and significant play that throws off guiding.

Has anyone else run into this?

- Do you also need to tighten the knob to an extreme degree?

- Any tips for securing the altitude axis without risking thread wear?

- Have aftermarket knobs or other modifications helped?

Im'm a mobile observer and I'm concerned about frequent loosening and extreme tightening and potential wear ramifications. I’d like to learn if this is a common experience among HAE43B‑EC users, or if my unit might have a tolerance issue. Thanks in advance for sharing your observations!
