    Hi, I have been using my Robo3D R1 plus for over a year now and it was working fine until a few days ago.

    I was printing something overnight and it completed perfectly over the night. I switched my robo3D off in the morning and when I tried to turn it on again a few hours later, I heard a loud bang and it's unable to be turned on anymore.

    I checked the fuse beside the power cable and indeed it's blown. I replaced it with a 250V 4A fuse and the unit still doesn't turn on. Expectedly, the fuse blew again (this time no sound though).

    May I know what is the root cause? My PSU looks fine and the cables doesn't look like it's short circuiting anywhere.

    I am thinking of getting this:
    https://www.aliexpress.com/item/360...11.html?spm=2114.13010208.99999999.264.EFkbcX

    The 500W one seems big, will it fit into the R1 plus PSU slot?

    Looks close to same size. Check the dimensions of it versus the ones on amazon
