Hello I propose this self-extinguishing printer module universal. It can be installed on any printer, provided you have a command output declared in the firmware (PS_ON) A printer that remains in standby consume about 30w, install an auto_off can prove advantageous I give the procedure for RAISE3D 3D printers https://youtu.be/RjYfSuyZBmQ
By default on Raise3D motherboards the output control (PS_ON) is declared on the pin 45 By default the commands are: M80 - Power on: pin 45: 0 M81 - Power off: pin 45: 1
This order order did not allow me to make a functional module I reversed the levels according to the commands. It is not possible to invert the Gcode commands, M81 does much more than pass the pin 45 to 1 (the M81 control cuts all heating up) In this way, it is not possible to operate the stop (PS_ON), when the stop occurs the pin 45 returns to 0, the machine restarts.
So to solve this problem it is necessary to invert the levels of the gcode commands Like this : M80 - Power on: pin 45: 1 M81 - Turning off: pin 45: 0
For this you have to go to the source code (MARLIN): MARLIN is the name of the firmware of many 3D printer including RAISE3D Raise3D provides the source code MARLIN Adapted for Raise N1 N2, N2 + https://github.com/Raise3D/Marlin-Raise3D-N-Series
In the configuration.h tab visible here https://github.com/Raise3D/Marlin-Raise3D-N-Series/blob/master/Marlin/Configuration.h, We must replace the line: #define POWER_SUPPLY 1 By #define POWER_SUPPLY 2 It is important to take the U8glib library which is with the source code provided by RAISE3D https://github.com/MarlinFirmware/Marlin/archive/1.1.x.zip I advise you to take the version of arduino 1.0.5 r2 to compile Marlin
It is not necessary to connect to the motherboard to inject the firmware. On arduino used the button "check" to compile, if the compilation ends without error, it is possible to find the file in .hex. How to do it here youtube.com/watch?v=PEhqzvO3egk"
It will be necessary to rename the .hex in .firm To deposit the file on the USB key or SD card. On your Raise Select the firmware file edit and press "OK" to update.
Another solution: We can manufacture a signal inverter The plan here https://4.bp.blogspot.com/-ceo1ufnsqK0/U1XGiT2PQZI/AAAAAAAABsk/wTUfNQONoh0/s1600/porte+non+transistors.png
Then it will be necessary to add in your slicer
Startup script: M80;
End script M109 R50 T0; wait until extruder 0 is at 50 ° C to go to the next line M81; power off pin to 0
NOMENCLATURE I used some recovery component, like the USB connector and LEDs that are easily found, I recycled the IEC 320 connectors recovered on old ATX power supply
