I built a Vise with two clamping jaws.
One slides forward hits a tool then moves forward again till it hits a second tool - then it clamps tight.
The return stroke puts everything back to where it starts.
I have limit pins at the jaw base - and have been able to make everything move in the assembly correctly - the assembly is fully defined - BUT the first jaw can ( slide through ) the second jaw.
When I add the extra constraint to make the first jaw push the second jaw till it hits it's stop - it all works, but now the assembly is over defined.
Why would the model be over defined if it does everything & works just like the real life version....?
Will the vise being over defined cause problems down the road when I add more tooling to it...????
