Thanks Rob
Update:
#1
Attached the MyFP2 focuser to a laptop running the MyFP2 Windows client (version 2.4.3.9)
MyFP2 firmware version: DRVHW203.290
Focus Position = 3207
Max Steps = 10000
clicked the {+100} focuser travel button
focuser moves +100 steps as expected
clicked the {-100} focuser travel button
focuser moves -100 steps as expected
Ran the above focus travel moves 3 times. Focuser moves as commanded
#2
Connect focuser through the indi connection GUI on a Raspberry Pi 4 running kstars/ekos under Stellarmate (StellarmateOS_1.4.3_rpi4.img)
kstars version: 3.3.7
Attempt to move the focus either in or out using the ekos focuser GUI (be ready to abort the focuser travel)
The focuser will continue to move well past the commanded number of steps
Abort the focus movement using the ekos GUI
On inspection, the ekos GUI appears to show that Max Position is set as it should be
In my use case, Max Position = 10000 (see my earlier screen capture)
Regardless, re-enter and set the Max Position value by entering the value for Max Position in the ekos GUI
Now set the focuser to travel in or out using the ekos GUI and observe that the issue no longer occurs; the focuser moves the defined number of steps without issue
Just as an FYI, after applying the manual workaround above, I had the focuser in service last night with ekos under the stars using Alan's indi driver in between the rain clouds
IIRC, I slewed over to Capella to use as a focus target
Ekos auto focus seems to perform as expected, so all's well on that front with the focuser achieving focus under automation.
Just need to get to the bottom of the "Max Position" issue
Will carry out further field tests as the weather improves
Validated the focus achieved via ekos with a subsequent Bhatinov mask test:
