Testing the lifting mechanism
Article #17 - 25/10/2021 22:58A little wobbly at the moment (I think because of the flexible joints between the stepper motors and the threaded rods), but working quite well.
A limiting switch has now been added to stop the motors going too far down. (If this happens then the captive nut gets wedged against the joiner).
One isn't required at the top as the steppers count how for up the base is. This also means the base can be manually lifted beyond the threaded rods for working on the electrics on the underside.
