gardner:
Do you have a mechanical design in mind? How will the motor actuate the slide? Are you thinking of using a cable system, a threaded rod or maybe having the motor directly drive the slider trolley on rubber wheels?
What sort of range of motion are you thinking of? Do you want to build a 3m slide or a 50cm one?
What sort of rail or track system are you thinking of?
This is the design, obviously it,s not mine, but its very very similar. Identical really:
The Igus 120cm rail, the stands, wire and all of that is already built and working just fine. The thing that I'm stuck on is how to interactively control the speed and direction of the motor in the best fashion possible.
Do you have any ideas on how to do that?
Thanks for replying. I appreciate it.
