i recently purchase a anycubic kossel delta everything was pluged in properly and when i plug it in it doesn’t power on please help me
You can check some basics but unless you are versed in electronics and electricity I can’t advocate tearing things apart to much.
First off look for a fuse in the power supply. These tend to be near or part of the power switch or is part of the power supply.
Also you can unplug everything from the power supply and see if you get any output from it. This will take a meter to measure.
If you can measure output then reattach your components to the power supply one thing at a time and see if it goes dead. The idea is you are looking for something that is shorting it out.
So, if you plug the power supply into the main board and you still get power then start plugging in the components one at a time and see what happens. sometimes it can be as simple as something plugged in backwards.
