Release Notes

We regularly release updated firmware versions to improve functionality. Review the firmware release notes to learn more about the improvements that come with each version's release.
Latest firmware version: 2.01

- Added in Dynamic Minimum Durations. This feature calculates minimum durations based on the distance traveled, rather than a fixed value. This allows shorter moves to run at a proportionally shorter duration. This feature also applies to Move to Start and Edit Keyframe moves, which will drastically speed up those moves when the distance traveled is less than the full slider length. *Please note that this feature can introduce some pausing at keyframes if the move includes changes in direction on an axis at too low of a duration. In those cases, the duration will need to be adjusted upward. 
- Added a feature called Fixed Linear Velocity (FLV). This is an ON/OFF setting within a Video Mode move that will ensure a consistent slide speed between all keyframes. *Please note that multiple keyframes are designed to have an even linear spacing between keyframes. This feature corrects any small discrepancies during setup, it is not designed to work for moves with large differences in linear spacing. For more details see this article 
- Fixed a few minor bugs
- Introduced the ability to set up to 5 keyframes 
- The Fast Focus feature has been removed and replaced with the ability to set multiple keyframes
- Auto shutdown has been defaulted to 4 hours (this means no user input and no move in progress) and no longer has a menu option
- Several menu options have had their layouts adjusted
- System level ramping updated from 1 second to 1.5 seconds
- Move to Start and Edit Keyframes now follows the travel path of the move.
- If a movement is canceled and then restarted (different than pause/resume), it will continue its move to the most recent target keyframe before returning to Start
- If you back out of editing a keyframe without setting a new point, all axis will return to the previously set keyframe
- Cleaned up some menu bugs within Advanced Timelapse mode that could allow an invalid duration and/or interval to be set. 
- The app has been updated to support setting up to 5 keyframes within a Video Mode move. - Fixed a number of bugs within the app related to setting up and running a move
- Please note that Time Lapse moves are not supported within the app
- Overhauled Menu navigation in preparation for 5 keyframes
- Added in sub-menus and changed layout of settings
- Added an Information menu that contains details on Firmware Version and certain codes to diagnose any issues or crashes
-Removed Auto-shutdown menu, now powers off after 4 hours of no user input
- Battery indicator now accurately displays charge level at all times (please note the unit will need to be charged for 10 hours to calibrate battery indicator)
- Increased maximum duration to 5 minutes for Video Mode
- Fixed a number of bugs around motor detection and movement
- Added in a error message in the event that a motor axis failure occurs
- When switching from app to hardware controls, the unit will reset. This fixes some communication bugs that could occur. (Note: This will cancel any move currently running)
- Resolved a number of system level bugs and overhauled several sections of code in preparation for 5 keyframes

All settings will be reset to Factory Defaults upon updating to 1.09. Please review before operation
- Battery level now correctly reports charge level of the batteries
- Fixed a bug upon updating firmware where the unit would report low battery, requiring a charge cycle to reset reporting
- Battery indicator (both when powered on and off) will now stop blinking when the unit reaches full charge
- Implemented Sleep Mode. Screen will not time out after one minute of no user input. This improves battery life. To wake the screen the Top Joystick needs to be moved in either direction (power button or clicking joystick will not wake screen. When charging, the screen will turn off after one minute. To check charge level, press Power Button once to wake the screen. Hold power button for 3 seconds to power on as usual.
- Modularized code base to standardize certain processes.
- Better handling of error messages and initialization which results in fewer system failures
- Redesigned the layers, modularized and standardized motor movement. This allows us to implement new features including additional keyframes
- Optimized move duration which results in more accurate duration
- Made some adjustments to motor current, which improves jittery footage
- When powered off, batteries will charge to full in 10 hours. The battery indicator may not reflect this (will be resolved in a future update), but will be fully charged. To reach a full charge, Arc II does need to be powered off. Leaving Arc II on the charger for over 12 hours will damage the batteries.
- Fixed a bug where simple time lapse did not allow long duration moves
- This firmware update for Arc II adds a lot of stability to the overall system.  
- Fixed an issue where the unit would not register its starting position during “Moving to Start” and would stall and prevent you from running the move. Note: Each axis now moves to start at a fixed speed. This is normal behavior.
- We expanded the Fast Focus feature to be user adjustable based on percentage of move. 100% means focus will change over the entire move. 20% means focus will change over the first 20% of the move. Note: If you have a large focus pull and set it to a low value (ie. whip focus), there is a potential to overdrive the focus motor (motor will stall but not be damaged). We’re planning on limiting its max speed in future firmware upgrades to avoid this edge case. 
- Fixed an issue where a move would reach its end but the duration would continue counting upward. This would cause some moves to not loop as they never registered they reached the end of the move 
- We added an internal feature that checks for system lockups and reboots the unit in the event of a lockup. This should address units that aren’t able to power on. 
- Reusing a move will reload the move settings if it is the same mode you enter back into (Video or Time-Lapse)
- We made a number of system wide changes in the firmware that adds stability when booting up and shutting down the system.  
- Due to some of the system changes above, the duration of some moves differ from the selected duration. These are typically edge cases when you create a move with extremely limited travel on all axis. If this is affecting your move, please feel free to downgrade to 1.04.00. We are working on addressing these edge cases in upcoming releases. 

Please note that the iOS app is being updated in the next few days to all for the new Fast Focus functionality. 
- Fixed an issue where the Tilt position was not being saved between keyframes 1 and 2. This happened when Tilt travel was less than 4 degrees.
- Fixed an issue where a previous moves settings would carry over into the setup of a move. This could make joystick control in a new move sluggish and unresponsive.
- Fixed an issue where Camera Size and Motor Location settings upon initial startup were being saved as opposite of what was selected. 
- Adjusted the feel of the front joystick to feel more responsive. Mostly affects Video and Time Lapse move creation. 
- Fixed an issue in Fluid View where you could not calibrate the Tilt axis when Heavy Camera was selected. 
- Fixed an issue in Advanced Time Lapse where longer duration shutter speeds would sometimes stall at the beginning of the time lapse. 
- Adjusted the order of operations so that you are always prompted to calibrate after changing motor types. Previously you were not prompted to calibrate if you had a programmed move created. This caused issues within the created move after switching motor types
