Joe, are your clutches tight? The fact that you hear motors whirring is a clue. If you left the clutches loose, the RA and DEC shafts could spin without moving the mount. But if the clutches are tight, you hear motor rotation, and you still see no mount motion, there’s got to be a disconnect somewhere in the drive train. Check belts. With the EXOS2 I can see motor rotation through the little gap in the motor housing; Maybe the IExos-100 allows that, too. If so, you could check that the motors are really turning and not just whining a little.

Subject: [ESPMC-Eight] Newb issues after firmware, ExploreStars Data Base update #iEXOS-100 #Android
It's been a while since I last used my iExos-100. I just flashed the firmware using the latest 1A01C_10B_5.eeprom
While doing the firmware update, I poked around settings in the Configuration Manager. Could I have screwed up a comm setting?
