It turned out the torque numbers I'd been given on those servo motors I was buying were peak and not continuous. Good thing I looked up the data on them via the manufacturers website! So now I'm back to choosing motors.
I'm still serious about the ClearPath servo motors if they put out enough power but it's hard to tell. If they won't do for 6DOF I might be back to AC motors. I've been scared off by the need for 220VAC supply but I see nearly all the good 6DOF rigs people here have built used AC motors.
Can anyone give me a good idea how many watts I need per motor for a 6DOF hexapod rig moving a 70KG (150lb) platform with a 77KG (170lb) pilot? I'm going to start shopping again.
-The AC motors are free wheeling when they reach the target and a "stop" command is issued. (they may bounce around the target if there is backlash in the reduction gearbox.), Manual calibration of PID values on the AMC1280USB controller may needed to avoid or minimize this.
-The Servomotors, will "brake" instantly when the reach the target, and HOLD position themselves (secondary position control from the integrated drive and enclosed quadrature encoder inside the motor). There is a Auto-calibration feature that you can run on the motors and they WILL calibrate themselves under load (6DOF platform connected with load on it).
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
