I have Ekos running a myfocuser2 with the latest .321 firmware on Ubuntu 22.04 and, despite all my efforts, I have the problem with linear 1 pass algorithm moving to the wrong solution.
For the moment I'm stuck using polynomial algorithm, which by the way works ok since my focuser apparently has little backlash. But the V-curves I get with linear1 are superb... so, since for what I understand there are no other options, I'm really looking forward to 3.6.2 hoping it will solve the problem.
