Artillery Sidewinder X1 Auto-Power-Off solution

thingiverse

UPDATE 16th May 2020: Added a PDF with my slicer END-CODE. UPDATE 2nd Feb 2020: The high inrush current of the power supply might kill the momentary power switch. I read in a forum that adding an NTC resistor in series with the switch can reduce the current and save the switch's life. A wide range of Ohm values are usable. Here are two possible types/sources: https://www.reichelt.de/ntc-widerstand-3-1-w-33-ohm-epc-b57237-s330-p240063.html https://de.aliexpress.com/item/32382713600.html I will try a 33Ohm resistor, but anything between 10 Ohm and 200 Ohm should work. UPDATE 25th Feb 2020: Final version schematic added (correction of NC/NO of relay and M42 command). UPDATE V5 -> If you use OCTOPRINT, the plugin "Temperature Failsafe" can be used to shut down the printer in case of over-temperature. I added a chapter to the description explaining how to configure this. WARNING! There is an error in the description (schematic). You must use the NO (normal OPEN) and the COM contact of the relay-board, not the NC (normal closed) contact!!! UPDATE: The G-Code command for switching is M42, not G42 as used in my previous documentation Also, please add these commands to the end-code of your slicer: M109 R50; set nozzle temp to 50°C and wait until it reaches this temperature M104 S0; set nozzle heating off Therefore, I have updated the description to version V4 English: After printing big parts using longer print times, I wanted an Auto-Power-Off because I didn't like wasting energy but also reducing operation hours of the printer. I tried with the classic method using the PS_ON signal and configuration in MARLIN FW. However, it failed. I couldn't make it run 100% after many tries and configurations. With the same HW configuration, just adding a 10kOhm resistor and without any FW configuration and flashing, I developed a new solution. Please find the description attached as a PDF file. The long version is in German but with some links. At the end you will find a short English version. In case of any question, please leave it in the comments. I try to answer quickly. GERMAN: If printed over Octoprint, one can install the Failsafe Temperature plugin and shut down the printer via this plugin in case of emergency. A description is inserted into the documentation. Since I was unable to get the Auto-Power-Off function or Power-Supply-Control working on my Sidewinder using M80/M81 in both "ATX" and "X-BOX" modes (Firmware modification), I developed another method to shut down the printer automatically after printing is finished. No firmware changes are necessary. However, modifications or additions will be made that also affect the 230V wiring. This can only be done by people who know what they're doing and are aware of the possible consequences! The entire guide can be found in the appendix.
