Hydrobot Interrupter Disks
Ah, April, when a young ITPer’s thoughts turn to… oh! crap! so! much! to! do!
Pictures from Hydrobot interrupter disk testing
Last night I tested the Hydrobot interrupter disks attached to stepper motors. The KP4M4 stepper was way to weak, but the ones I got from Jameco should work well. They can go pretty fast, but I will have to start them slow to avoid missing steps. The “spider” shaft couplers (rubber cross between two metal pieces) I got from Jameco are nice but using them means I need some way to trap the interrupter disk shaft axially since the coupler doesn’t provide any axial attachment.
