I have the same problem with serial timeout errors with the Moonlite BUT the focuser on my setup doesn't work at all, i.e. it doesn't move on command - see log file below. It used to work ok and I've not _consciously_ changed anything! I've done a bit of troubleshooting - I'm on a MacBook Pro running Catalina 10.15.2 with Kstars 3.3.8. The log file below is from a debug session when attempting to move the focuser. Everything appears ok in that the messages seem correct but the focuser hasn't actually moved. The slip clutch is correctly tightened and the focuser works fine in a Virtualbox VM running Windoze 10 and the Moonlite non-ASCOM utility, and it moves to the correct positioning when instructed, just not when using indi - this indicates to me that the USB-serial driver is operating correctly. I don't know whether the serial timeout errors are connected with the focuser not moving or a just a red herring. I really don't want to be running a whole VM just to operate the focuser - please help!
