Hi! I will be grateful if you help. I'm not sure the right motor switched output to THANOS board. I'm not sure this is correct? I have everything ready mechanics electronics only need to configure correctly
Thanos, you told me that it was possible to rotate 360 ° non stop, what is the problem? I'm not understand his problem
Its not really a problem, than a missing function at the moment. What I have to add is speed control with artificial PID that deals with no limits thus to be able to get beyond the 360 degrees of the sensor. I could do it sensorless but then there is no really way to tell the home position.
My plan it to use normal PID with separate value than the rest of the motors for YAW on start-up / stop motion states, and then switch to the hybrid mode open-loop PID during normal play of motion simulation.
Doing my best to prioritize all these requests to be implemented as soon is possible.
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.
dureiken: Hi there, it's really quiet here someone could help me for my 6 dof project ? thanks a lot

tronicgr: dureiken Hi, Open a thread and I'll try my best to help. A little busy with Kickstarter details at the moment but I'll see what I can do.

fimmy: How's the firmware going?

tronicgr: @fimmy I had to put it on hold to finalize the manufacturing of the new kickstarter controllers. I tested parts of it to ensure compliance with the new features and looks good so far. I'll get back to it soon for integration.

Theuns: Very nice design.I'm also busy with mine and changing it also to Linear Actuators with 220v Servo motors.I'm waiting for my new controllers from Thanos. If I may ask Do you have any Sketchup files of your design and willing to share it I Thanks Theuns

atayeu: Hey everyone! I'm reading up and gathering all of the intel I can find for my first motion platform. this is by far best information for creating one.

tmcnam: I must be crazy but I still can't find the blueprints to the platform by GA-Dawg. Any help would be appreciated. Thanks guys.

Trip Rodriguez: Sorry tmcnam, the shoutbox doesn't get much attention. Did you find the blueprints? They are at the VERY bottom of the extremely long first post. It says "attachments: 6DOF.zip
