Bug: "Fit" algorithm ignores Cut off value

Recommended Posts

The code that determines whether an object will fit for printing seems to ignore the "cut off bottom" value.

I am trying to print an object that is 210mm high on an UM2, which has 205mm as maximum height. I can cut of whatever I want from the bottom, it still shows as non-printable. It's not exceeding maximum directions in either X or Y.

Thats the danger of cnc machines and 3d printers. if you give them instructions they will perform them even if they cant. Thats why you need to be vigilant about it. But if you know you cut off 5 mm then you should be fine.

I cheat the granty height all the time when one piece (the last one being printed) is taller than the normal value.

Anyhow... just printed the piece at full height (210mm) and I had about a cm of Z to spare.

 

Makes perfect sense. The early UM2s had a 10mm longer print head then the newer UM2s. And Cura is setup so both version work safely.

So yes, you have 10mm MORE Z space then advertised.

dirkdirk... Measure it :) That's what I did to make sure the piece would fit! :)

From the bottom of the nozzle onto the buildplate at its lowest. Just make sure to have some spare room as - at the end of the print - the plate will always rise about 1cm and go back down before it homes apparently.

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
