Hi Jasem

I cloned the git repo, rebuilt locally and installed everything.

git clone --depth 1 github.com/indilib/indi.git
mkdir build/indi-core
cd build/indi-core
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ~/Projects/libindi/indi
make -j4
sudo make install
ls -latr /usr/bin/indi_trutech_wheel

Confirms just built version - maybe I messed up by installing everything from master?

Now the filter wheel tab throws an error on startup as attached. I had a good look around for more detailed and accessible log files on my pi (I'm running a Raspberry Pi btw). I'll go back to the manual to see if any locations are listed but if you can point me to where they might be?

Everything else seems to still work. The good news is that the problematic filter size parameter is now gone from the Options tab!
