Re: Open (i think) design for a parallel robot (reprap may be interested)
I was only thinking of the 3dof machines for the glue-gun application as opposed to the 6dof stewart platforms. As near as I can tell, the transforms for those don't have singularities, but I could be

From a Machinists view and knowing basically what is required for general machining. The Stewart platform, although clever and innovative would have to be built on a massive scale to even be adequate

No it has to reside in C:&#92;Gear to work, - THEN it will generate the library. Inside W2K it can't make the folder C:&#92;gear, you have to do this and put the exe file into this. On your start

Re: Open (i think) design for a parallel robot (reprap may be interested)
I'm curious about the Stewart platform, and what kind of actuators might be salvaged to create a small one - like meter or less in dia? I suppose just some salvage steppers with threaded rod, but if

I'm suprised it hasn't gone already. All you read are posts about people whinging about "I can't find a mill etc. " and when one pops up they convieniantly ignore it then post later "I wish I had

Re: Open (i think) design for a parallel robot (reprap may be interested)
Dear Dennis, Thank you for the tip. I think we'll start about by making a cartesian robot, i.e. some traditional mill/gantry/router type thing, and then eventually move over to a Stewart
