Hello! It’s been a crazy week, but I do feel the need to express it here since I made a promise I couldn’t keep about my project.
My 3D printer arrived on wednesday, the day I was going to update the mecanium rover’s part list and start some new tasks. I thought the build process wouldn’t take that long so I started assembling the printer from nothing to something that moves and prints physical objects.
On wednesday I spent 12 hours without any break assembling it. I did stop once to eat but that didn’t take much time. Then the day after I spent an other 3 hours finishing up the wiring and fixing clogging issues in the nozzle. So a total of 15 hours of work to make it all be as sturdy as it could and have all wires managed as good I could.
Then I managed to do a real first print, a small simple cube meant to detect any small print issues. The cube turned out great considering there’s no cooling yet and it was only a 15min print, so nothing too hard on the printer. Then I decided to print an object that would take about an hour to be printed, which is considered a small simple object in 3D printing.
At around 75% of the print completed, I heard a single loud click from the printer. I ran to it to see what had happened and everything had turned off, nothing was moving, not a single light was lit up. The power supply was busted. It was burning hot and I believe there was a faint smell of unknown chemicals surrounding it. I came to the conclusion that it must had been one or multiple capacitors that popped.
So now this is where I am at, I need to fix my new printer and the manufacturer doesn’t seem very helpful. So I’m planning to make a conversion circuit to take an ATX computer power supply to power the printer. However I really do not like the idea of cutting wires on an expensive piece of hardware to turn it into a single-purpose device. So I decided I would make a little board into which I can plug standard 24pin, cpu 8pin and PCIe 6pin connectors and turn them into useable power plugs for the printer. This solution will cost a bit more than my initial budget but at least I’ll be able to replace the power supply at anytime very easily.
Hopefully this explains why I’m late on my project updates. I will try to update them some more today or tomorrow but fixing the printer is my main priority right now, because I spent too much time on it to give up on making it perfectly work.
