Anet A8 - Auto Shutdown

thingiverse

Here is my project to auto-shutdown the printer at the end of printing. the project is divided into 2 parts, the first being the switch box, the switch is a standard built-in switch that you can also find on amazon, as a cable I used a 2X0.75mm sheathed wire, recovered from an old power cord of a radio. this first piece must be fixed together with the screw of the hole cover of the steel bar of the Z-axis. the second part must be mounted on the extruder carriage with 2 M4 screws, I have used those already present on the X-axis bearings. after printing and assembling the parts, you have to modify the fine G-Code from your slicer, the one I use I leave it below so you can copy it. IMPORTANT In order for everything to work perfectly before gluing the G-Code, check the height between point 0, i.e. your hot-bed, and the switch, for my printer I have set 238mm, if necessary go to modify the line '' G1 Z238 F3600; move 238mm to the top ''. For example, if the measured height is 220mm your string will be: '' G1 Z220 F3600; move 220mm to the top '' Enjoy! END G-Code M104 S0; extruder heater off M140 S0; heated bed heater off (if you have it) G91; relative positioning G1 E-1 F300; retract the filament a bit before lifting the nozzle, to release some of the pressure G1 Z + 0.5 E-5 X-20 Y-20 F9000; move Z up a bit and retract filament even more G28 X0 Y0; move X / Y to min endstops, so the head is out of the way G90; absolute positioning G1 Y190 F9000; use this line if you want the bed to move to the front. delete if not. G1 Z238 F3600; move 238mm to the top G1 X210 F3600; move 210mm to the right G1 X-10 F3600; move to the left M84; steppers off
