Let cams move a shaft in Inventor
(OP)
Hi,
I have made a small basic motor in inventor. I have constrained the drawings in a way that the motor runs correctly, however there is one error. The cams on the camshaft need to push up a shaft that is connected with the valves. Is there a possible way to let the cams push the valve up and down.
Screenshots of the problem:

I hope to hear from you. I have tried many constraints in vain. Any ideas are welcome.
Kindest regards,
mab

Your next problem will be the spring - did you want it to deflect with the cam motion (acceleration), or is it just there to look pretty? I'm not sure how to link the spring length to an assembly parameter, but know it can be done.

i suggest you check S.Dotson website for tutorials.
there is one for relative motion, where you define a plane, say on you shaft centerline, then using a formula relative to a known "clocked" position on the shaft relative to the bottom of you piston. Simply put, one o'clock - up .125, six o'clock - (max rise) up .5, 8 o'clock - down .38, etc.. Your part is constrained by a formula.
There is also a tutorial there on making the spring length adaptive so that it will work as well.
good luck.
