I have been working with a scissor lift and everything was moving along great - - then boom.  I have a hydraulic cylinder that I apply a linear motor to.  I add the payload and qravity and our results were right in line with the hand calcs.  Now the forces are in the tens of millions, has something changed?  I have not made any changes to the system.  I am working in SW13 premium.  Before I dive into it I wanted to see if I missed a memo.  Thanks in advance for any suggestions.
