Equipment Needed:
- eMotimo SA2.6 with firmware SA2_RC001_008_SP1 or newer
- Dragonframe 4.1 or newer
- USB to USB-C Cable or Network CAT-5/6 Cable (coming soon)
1 - Update:
Make sure you meet the minimum firmware version: SA2_RC001_007
2 - Cables and SA2.6 Connection:
Option 1 - USB to USB-C Cable
- Power on the SA2.6 and go to the Settings->Port Settings->VCOM Port, and choose the 'Dragonframe 4.1+' Option.
- Exit the Port Settings menu to save your changes. This setting will then be maintained after power cycle so you only need to do this again if you change it or upgrade your firmware.
- Connect the USB-C cable to the SA2.6 and the USB cable to the device running Dragonframe
- Return to the Main Menu or Power Cycle the SA2.6
Option 2 - Network Cable - Not Supported Coming Soon
- Power on the SA2.6 and go to the Settings->Port Settings->Network Port, and choose the 'Dragonframe 4.1+' Option. This setting will be maintained after power cycle so you only need to do this again if you change it or upgrade your firmware.
- Connect the CAT-5/6 Ethernet Cable to the SA2.6 and to the router of the network that is running Dragonframe
- Return to the Main Menu or Power Cycle the SA2.6
3 - Dragonframe Connection:
Option 1 - USB-C Cable to your Dragonframe computer
- Start up Dragonframe and create a new scene.
- In DF, go to Scene-->Connections... Menu
- Click the Add Connection button. Under Device, select "eMotimo spectrum ST4", then select ArcMoco #1. Watch out, don't just select "eMotimo" here as that it the old protocol that doesn't support real-time moves and it just won't work!
- Under location, select the serial port of the cable you just added. This cable will be named differently and may change if you install on a different USB port. If there are multiple connections you may have to try each to understand which one is connected to your SA2.6 Conductor.
(Note, we will ask dragonframe to add another connection type for this controller, but for now selecting eMotimo Spectrum ST4 is just fine) - Once selected, click the CONNECT button. Within 3 seconds it should say connected and turn green. The Status should read: Connected to eMotimo SA2 - V1(1.7.0) these numbers will vary with firmwares.
- Close out of this window by clicking OK.
- Your SA2.6'screen will change to one that looks similar to this <insert image>
- In Dragonframe, from the top menu, select Window --> ARC MOTION CONTROL
- Import your axis Settings – for convenience, we have created an SA2.6 .arcx file with the default axis filed for the RS3 Pan/Tilt/Roll/Focus + Dana Dolly Slide(M1)/Turntable(M2) and the Tilta Nucleus Focus/Iris/Zoom. Click here to download the axis file for the SA2.6+DanaDolly+RS2/3+Tilta or find other options at the bottom of this article. The main reason for this file is to get the steps/deg/inch working correctly and the correct channels assigned.
- Import the Arc Axis Setup by hitting the menu icon
and then selecting Import-->Arc Axis Setup (arcx) - Select and import the recently downloaded ARCX file SA2_030624.arcx. When correctly imported your ARC MOTION CONTROL window will look similar to this.
- Make sure you are connected and then use the Jog buttons (blue arrows) to move the head around and ensure connectivity.
- We recommend removing the axis you aren't using to keep your workspace clean (Brian's note - yes our SA2.6 is actually a nine axis controller - pretty cool, huh?)
- Build a move and play!
Option 2 - Network Cable - Not Supported Coming Soon
- <update when supported>
Notes for using Tilta Motors with Dragonframe:
Tilta motors are different than our other motors. They receive values from 0-9999 which is the relative position between their programmed stops. In other words, Tilta motors have 10,000 positions between stops to move the motor for your particular Focus, Zoom, or Iris's stops.
- Set your limits on Tilta Motors before programming through Dragonframe. If hard stops are good enough, use auto-calibrate for the motors.
- If you want to limit below that, use the hand controller and Tilta Documentation to set your limits
- Once limits are set for the lens, you can program from Dragonframe.
- Watch your motor numbers! Makes a difference on which axis is controller what!
Set your Focus motor to 1, Iris motor to 2, Zoom motor to 3. This is displayed on the Tilta Motor. - If you calibrate your lens differently on subsequent shoots, your recalled positions will be different.
Known Behavior :
- GoMotion not supported
- Backlash compensation setting are sensitive to direction and sign. Results in issues with jogging through keyframes – use of these is not recommended. This is more of a configuration thing than an issue with setup or software.
- The PS4 gaming remote, when connected, slows or stops jogging through DF (controls are battling). We don't recommend having the PS4 Dualshock remote connected.
- RS Focus motor is not fully supported as of SA2_RC001_008
