Geordio,
Have you tried assigning limits to the joints that you don't want to move? It's not the "correct" method but it works. If you go into the joint axis properties you can assign limits to the pin joints in degrees. Just make the limit a very, very small number on the joints that you...
Thanks for the information gentlemen.
Should I be calling it a coldfingeras opposed to a heatsink?
Anyways.....Is there any advantage to maximizing the mass of the heatsink so it will store/maintain a cool temperature to help increase cooling rates when energy is applied?

Hello,
Can anyone offer advice on the design of a finned heatsink that will be submerged in liquid nitrogen to cool an analytical instrument? I am a mechanical engineer with minimal thermal experience and I am designing a coldfinger or heatsink that is attached to a heat source. The...
Mike,
Here is a cough drop for your throat... [thumbsup]
So does that mean "power" never gets cut-off to any of the three axis? The servo motor receives a sinusoidal pulse width modulated signal from the driver which controls it's velocity. If this x-y-z pick and place system established...
I have met with a rep from Maxon Motors to get more information on servo motors and their capabilities. Maxon informed us that the resolution of their encoders can control shaft postion to +/- .18 degrees. With this resoultion the tolerancing challenge lies in the lead screw - a fine lead...
Hello,
I am designing a "pick and place" mechanism for a new project I have been assigned to. I am a mechanical engineer with very little servo or stepper motor experience. This motion system will be three dimensional (x-y-z) with motor (brushless servo or micro stepper) driven lead screws. I...
