Adam Wienke – :
Hello!
Ich got my Focuser today, and discovered, that it’s not possible to
move with steps of size “1”. With the value of “2” the EAF is moving.
E.g.:
I move 72 times with 2 steps and get the current position 144.
I measure a movement of about 0.5mm.
Then I move to Position 0 and the Focuser moves back to 0mm.
After that I move 144 times with 1 step and get the same positon
readout of 144 as in the first attempt.
At this point, the measured distance, between the start position
and the final pos=144 in single steps, is 0mm(!)..
Setup:
Windows 10 Pro
Ascom 6.4 and 6.4 SP1
EAF Setup 1.0.1.8 (FW 3.1.5)
I tried with ASCOM and with your SDK (EAF_Windows_SDK_0.1.0524.zip)
in Visual Studio 2017 (Console Application) with exactly the same result: With step size 1, the focuser
didn’t move.
I guess, there could be a problem with the Firmware, because I had this issue
in Ascom as well as in Visual Studio 2017.
Sincerely yours
Adam Wienke

Thanks, JohnB.

You can add a hub on the ASIAIR box.
If you are using a cooled camera, you can use the hub in the cooled camera.
