tronicgr, can you do next revision of AMC1280 board with 7 axis 6dof, the extra axis for unlimited yaw position

tronicgr, can you do next revision of AMC1280 board with 7 axis 6dof, the extra axis for unlimited yaw position I could, but I'm not sure the software would support it. Why would you need extra yaw anyway? Right now the yaw is using washout right from the motion cues. Thanks Thanos |

Hi all, I did some tests for online offline switching of the feedback for Yaw so it in 4DOF it can be used to position the platform back to home position. For this to work, a 360 degrees sensor is needed without endstops. A few days ago I got some small motors with double output shafts on their 40RPM gearbox and very small current consumption. I literally can power these motors directly from USB!! So I'll be making a 4DOF model with them as it easier to work on the model and validate the firmware changes. I plan to combine the 3DOF axis in the controller instead of having to do it in software. Its not so hard and will be easier for users just to feed pitch/bank/heave/yaw information directly in the controller, less headache in the software side. I already hooked up one of the motors to axis 4 (Yaw) and did the changes for switching from positioning (offline mode) to continuous 360 degrees rotation (speed and direction control). I also implemented smooth transition algorithms for the online-offline switching that will be global (in all axis). See the video of the YAW fix I did so far. Firmware update will be released as soon I short out the algorithms and finish some more tests. www.youtube.com/watch?v=ke5-mSqJ8HQThanks Thanos I finished the first revision of the 4DOF function in the firmware. It has individual PID setting for the 4th motor (YAW) and the rest axis are still in same PID range. To activate it you need to set: 1. Plarform type: 4DOF 2. Sensor direction: 4DOF P1-3-Y, N2 3. PID setting for YAW: 15 or more Remaining code to add, combined math axis for the motors 1,2,3 to be able to feed to it directly axis effects as Pitch/Bank/Heave. I'll include a small drawing for the numbering position of the motors. Firmware revision 'a' with independent axis is this one: www.dropbox.com/s/ixg9f0ladhl1mo9/enc_6dof_AMC1280USB_v21a.hex?dl=0Thanks Thanos valmar |

Thanks Thanos extra spin for realistic accidents... yeah i think not possible for the software to produce two different yaw duration  |

Hi, How it´s going with the 4dof project?
Was new tronicgr firmware tested?
Do you use BFF software?

Hello tronicgr,
I didn´t received any reply to my questions. Do you have information about the project?
Thank you

Still working on the combined 4dof mode. Too many things to take care at the same time, but it will be done.
I checked your tracking, and seems the post office scanned different label than the one they put on it, no easy way to find the actual tracking number. It should arrive to you soon.
Thanks
Thanos

Today I received the boards. Thanks a lot!!!!
The firmware included allows 4DOF. I can set different PID for YAW, 4st DOF without position sensor, or ?
Thank you

Thank you Yes with included firmware you can set different PID for 4rth axis (yaw), and use it without potentiometer for unlimited 360 rotation when it receives motion data. However it still requires a potentiometer for home position of yaw when its in offline mode... And the other axis are not combined in the firmware on the board you received yet. This means you will have to combine the axis in the motion software. Hope that helps. Thanks Thanos |

Hi troncgr, I get the board setting for the 4dof as you teach me, ok: I select: "sensor direction 4DOF, P1-3-Y, N2"  ![]() ![]() Which is your software advice for my application (fast 4dof, combining dofs movements)? |

Bom dia Paiva
Seu simulador 4dof 360° yaw já está funcionando?
vc pode fazer o favor de informar seu email ou enviar um email para mim(ikesimuladores@hotmail.com)
