<p>I have made a temperature ⨉ fan speed tower which needed 3x9-1 ChangeAtZ post processing scripts and it took me quite much time to configure them all (and check it twice). Is there a way to save this, so that I wouldn't need to make them all again if something went wrong and I needed to start over or if I wanted to do something similar again ?</p>

I am adding this answer to help anyone else who has a similar problem.</p>\n\n<p>I strongly recommend that you buy a multimeter if you have any power supply issues, as this helped me to figure out what was wrong.</p>\n\n<p>There were three issues that needed to be rectified before my printer would turn on. The first was that I had bought a fairly cheap EU to UK plug converter from my local supermarket. This was mistake number one, as the quality was low and there was no ground pin for the power supply (which is dangerous). I plugged the EU plug into my converter, and then the converter into the UK mains socket, and it would not turn on. By using my multimeter I was able to figure out that the converter was a piece of rubbish. With the plug still plugged into the converter, but the converter removed from the mains, I touched my multimeter cable, whilst in continuity mode, on one of the three pins on the UK side of the converter (the bit that goes into the wall), and the other cable onto one of the terminals that I had connected the power cable to the power supply with. I touched each terminal in sequence to see if it was electrically connected to the pin on the converter. I repeated this in sequence and identified that the live pin on the converter was not connected, and so no current could flow when plugged into mains. I immediately defenestrated the converter. Here is the replacement that I bought:</p>\n\n<p><a href="https://www.amazon.co.uk/gp/product/B00QGYY5DC/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&amp;psc=1" rel="nofollow noreferrer">EU to UK converter</a></p>\n\n<p>The next issue was that the power supply cable was wired up incorrectly (or at least unintuitively). In continuity mode again, I touched one multimeter cable to one pin on the EU plug of my power supply, and the other to one of the terminals (which were connected to the wiring of my power cable.) I discovered that the live and neutral wires of the power cable were wired the wrong way round on the plug (in order for it to be used in a UK converter, not sure what the wiring convention is on mainland EU). In the UK, the right hole in the mains socket is live, the left is neutral, and the top one is ground. On the EU plug I had been provided with, the left pin was live and the right pin was neutral. If I were to plug this in to the new converter in the normal orientation (cable coming out the bottom side), the live and neutral would have been connected incorrectly (plug-live -> converter-neutral, plug-neutral -> converter-live). Hence, in order for the pins to be situated correctly in the converter, and subsequently in the mains socket, the EU plug had to be plugged into the converter upside down (plug-live -> converter-live, plug-neutral -> converter-neutral). </p>\n\n<p><strong>Finally, the official instructions for the wiring of the Anet A6 are wrong.</strong> If you follow the youtube video that they provide, you will see that the positive terminal is closest to the bottom of the diagram (on the thermistor/endstop side of the board). <a href="https://youtu.be/mQzOHL_89nc?t=1530" rel="nofollow noreferrer">Mainboard wiring instructions</a>. THIS IS INCORRECT. Check your board, as the polarity will be printed onto the board. If you wire up the mainboard according to the instructions, your V+ wire will go to the negative terminal of the mainboard and, your positive terminal will go to the COM wire of the power supply. This is wrong, as the positive terminal should be connected to the V+ wire, and the negative to COM.</p>\n\n<p>Hopefully this helps save someone some frustration and time!</p>\n'}]
