Indeed, the second is what I want. The video is most instuctive, thanks.

[how do I make a solid volume within a larger volume?]

I want to make a 'solid' box, several cms in each dimension and within that box I need to place some solid volumes to screws to be inserted.

How do I go about this please.

I'm using an O+ with Cura 3.4

[UMO+ Where to Begin?]

I've just completed building my printer following the excellent instructions.

Now though I feel high and dry. The manual provides a link to the website for configuration and calibration.

It's not obviuos which version of Cura I should use. I installed Cura 3.

On first use it suggests I make some checks. the first page allows me to test the nozzle and bed temperatures and informs me that the limit switches have not been tested.

Then I move to levelling the plate and start the test. The plate is positioned several mms below the nozzle such that I can make any adjustements.

I've tried searching the forum and website  for a dummies guide but I've failed.

Has anybody a set of instructions on how to get started. It's a shame such a set are not included with the printer.
