FAQ

What is the difference between AstroLink 4 mini and 4 mini S?

Only the enclosure has been changed. It is now 3D printed and is available in three different color versions. All connections and functions remain the same.

AstroLink 4 mini is not detected in the computer Device Manager

It may happen, that Windows does not fetch drivers from the Internet automatically, or this option is disabled. In this case, you need to disconnect AstroLink from the computer, download and install FTDI drivers ( https://www.ftdichip.com/Drivers/VCP.htm ), restart the computer, and connect AstroLink again.

AstroLink panel software does not start

When you play with AstroLink settings and connect the AstroLink device to different computers it may happen and you need to delete the local computer AstroLink settings folder. You need to
1) uninstall AstroLink panel software
2) find c:\Users\\AppData\Local\Microsoft folder
3) remove AstroLink4.exe_different_characters_here folder
4) install AstroLink panel back

What about AstroLink 5?

The roadmap for the next year or two is:
– focuser controller integrated with focusing motor
– AstroLink 4 mini with the integrated USB hub

AstroLink 4 does not work as expected, what should I do?

Check the Troubleshooting Guide in the manual https://astrojolo.com/astrolink4mini/doc/Troubleshooting.html . Check the device with a different computer, different cables, and different power supply. If the problem remains, contact us using the Contact page.

Why AstroLink 4 does not support microstepping?

Microstepping seems to be a tempting solution with regards to precision. However, it carries its own problems like constant power drain, heating, and incremental torque (see more at https://astrojolo.com/astrolink-4-0-mini/focusing-stepper-motor-solutions/ page). Future units (EZ Focuser and AstroLink 5) will natively support microstepping, so you will be able to check this solution by yourself.

What about INDI support?

AstroLink 4 mini and 4 mini S have now dedicated INDI drivers. It can be downloaded at https://github.com/astrojolo/astrolink4 page.

Why don’t you 3D print with PLA?

PLA is an excellent material for many purposes, and also easy to print. However, it gets softer at temperatures 50°C and above. And the temperature at this range is easily reached inside amateur observatories during hot summer days. That’s why currently printed elements are made with PETG and Impact PLA materials, but we also test other ones.
