Yesterday I finally managed to get to work on the new printer ( Creality CR-20 Pro) and to begin with it, drove me mad and I came very close to packig it up and sending it back. Assembly was fine, quick and easy, but tryng to zero the z-axis was a complete 'mare. I spent about 2.5 hours following a YT video by "3D Printing Canada" which was really easy to follow, but I did it time and again following each step and checking before moving on to the next, but the zero setting just would not save.
Eventually I went back to a video by Creality themselves, which has the English subtitles mixed up with the Chinese ones and is not exactly easy to follow, which is why I had looked for another one originally.
However by concentrating and following it one step at a time, I managed to set the zero first time. The Canadian video seems to actually have a couple of steps either missing or badly worded.
Anyway, without changing anything from the defaults on either the printer or Cura, I tried printing a small item from my collection of stl's and 10 minutes later I had a perfect print!
I then tried something a bit larger and two hours later I had a 2nd good print.
Soooo... gritting my teeth and crossing my fingers... middle of the evening, I set it to print the wagon body that I was trying to do when the old printer gave up the ghost.
9&1/2 hours later ( Well, 1st thing this morning), THIS is what was sitting on the printer bed:

I am amazed at the quality of this print straight off the bed and just using the default settings and as you can see it needs minimal cleaning up and the surfaces are brilliantly smooth. One small point which has really impressed me is the tiny hole in each of the strapping ends. I drew it but but never expected it to print ( it wouldn't have done before) being only 0.75mm diameter, but all 4 have a clean hole through.
The only slight negative is a small 'elephants foot' effect, which is something I've never had to contend with before, but I'll sort out in future.
I want to have a bit more familiarisation time and then I'll have a go at the Raspberry Pi/Octoprint.
