A Crash Sensor For Delta 3D Printers

A Crash Sensor For Delta 3D Printers

Unattended 3D printing is even more thrilling if your delta printer’s effector platform attaches to the delta arms through magnetic joints . While magnetic joints have their benefits, a small irregularity in the printing process can cause them to detach. The unknowing printer will then continue to drag a half-attached effector around, until the whole thing, including the still running heater block, comes to rest somewhere. [Lucas’] crash sensor tackles this issue by adding three limit switches. Each switch sits in a 3D printed mount that attaches to one of the delta arm pairs, effectively detecting if the rods are still in place
