No power to 3d printer please help

[Rob23]

Hi, I'm new to this forum and 3d printing. I recently bought a replica pursa i3 and assembled it correctly (I thought), when I first switched it on it immediately blew the fuse in the power switch. I then used a new power supply and wired everything correctly with a new 8amp 20mm glass fuse, now the lcd will light up but only when the usb is connected, I can heat the bed up with the options on the usb but I can't get any power at all using the plug socket, when I do plug it in and switch it on I get a green light on the power supply and audrino board but nothing powers up. Any help would be greatly appreciated

if you power it up and connect it to your computer via usb can you connect to the printer and print?

There could be some errors in the setting and calibration of the 3D printer. All you need to do is consult the user manual of your 3D printer and match the settings to know the exact fault.
And if possible, try getting help from the place you got your 3D printer.
