This is plainly not safe. A desk with memory needs to require a continuous button press to keep advancing the desk, so that if the operator or someone gets caught in the desk and can’t push the stop button, it stops as soon as pressure is released.
- pbhjpbhj 6y agoFall-safe buttons would probably be ideal too - recessed/covered to minimise accidental contact. You don't want to collapse against your desk and have it crush your legs (though the motor/gearbox probably isn't that strong).
- ponker 6y agoThe motor could easily be that strong, depending on how many pounds loading the desk is rated for. My standing desk is an expensive model but it's rated for 600 pounds.
- ta576248_743568 6y agoIt would probably be better to just implement continuous current (proportional to torque which is proportional to force up/down) limiting on the motor, that would prevent the desk from pushing up or down at a force that could injure someone. Not sure if this is directly controlling the motor or just communicating with the actual motor controller. If the motor controller is separate it may already do this.
