Dear SGPro,
I’ve performed the following steps.
- Use “Temperature Compensation Trainer” to perform training and I got -135 steps / deg.
- Checked “Temperature Compensation” and set the value -135 into the “Steps/deg” box.
When temperature changes, the focuser is not moving at all. I also did a search in the SGP log file and found out there were no “Temperature Compensation” keywords.
Did I miss any settings? One of my AP friends also reported that the temperature compensation stopped working recently.
Thanks,
-Min from Dallas
Found this in the log, not sure what it means. Could anybody help? Thanks!

If a min threshold for temperature compensation is not defined by the user, SGP will use a value of 15 % of the AF step increment. In your case, the AF step increment is 800 steps, 15 % of that is 120 steps. So if the calculated correction is less than 120 steps, SGP will skip the correction.
You can set a lower value for the min threshold, see: 353: Temp Comp - Set Min Threshold? .
