Topic: Incredibly bad rings from my Da Vinci 1.0

Hi Guys, new to 3d printing and getting really bad prints from my Da Vinci 1.0
Below is a pyramid 20mm x 20mm x 20mm but it prints out only 18mm high and about 2mm too wide all round.
I'm using the latest xyz firmware and host, ABS at 0.3 layer height. My bed level is 225,225,225 with a layer of blue printers
tape on it. Oh and I printed it at standard speed.

Any ideas what I'm doing wrong?

Straight away from the state of the top of the print is your layers are not cooling before it places another layer on top. You either need to cool the print down via a fan or stop it from printing before it cools.

Yeh, i solved the top by printing 2 of them one in each corner of the bed and having a fan blowing on it, but the bottom few layers are a mess, using a feeler gauge I have a 0.1 mm gap between the head and bed, I've printed 6 now and all suffer from the bottom few layers being squashed together.
