Automatic power off for Ender3

thingiverse

Holder for microswitch with roller, for automatic power off of Ender3I decided to design this thing to automatically turn off the printer after printing is finished.While the hot table is in the X-200, the table roller holds the microswitch in the off position.To install it, you will need:-2 screws M4 12mm-2 nuts with hammer head M4-electric cable 20 cm-MSW-13, Microswitch with ROLLER 17mm ON-(ON) (5A 125/250VAC) SPDT 3Phttps://www.chipdip.ru/product/msw-13Installation:-Solder the cable to pins 1 and 3 of the microswitch network cable-Pass the cable through the hole in the holder to the other side.--Push the microswitch into the holder all the way into the housing.--Remove the X direction tension roller-Install a pair of TNut in the right groove of the aluminum profile--Return the roller to its place.--Insert this wire into the printer's power gap, and securely isolate the connection point.Check the final code:{if max_layer_z < max_print_height}G1 Z{z_offset+min(max_layer_z+2, max_print_height)} F600 ; Move print head up{endif}G1 X5 Y{print_bed_max[1]0.85} F{travel_speed60} ; present print{if max_layer_z < max_print_height-10}G1 Z{z_offset+min(max_layer_z+70, max_print_height-10)} F600 ; Move print head further up{endif}{if max_layer_z < max_print_height0.6}G1 Z{max_print_height0.6} F600 ; Move print head further up{endif}M140 S0 ; turn off heatbedM104 S0 ; turn off temperatureM107 ; turn off fanM84 X Y E ; disable motorsI didn't write this code myself, but I was already in PrusaSlicer
