Cura 2.7.0 hickups

[PhilipC 0]

Hello all

I'm new to 3D printing and Cura so some of the errors I'm getting may be USER ID : 10T errors but I'd still appreciate any advice.

1. I use my 3D printer mostly to print off wargaming terrain and I have found that certain files routinely get loaded into Cura ~ 0.03-0.06mm above the Z-axis. This is not a problem if I recognise it as I just lower their position on the Z-axis and the print occurs normally, If I miss it however the model doesn't print a brim, the print curls and falls over later in the print causing a print failure. I initially thought this was due to the model itself, however I have contacted the file producer and he has been unable to replicate my issue. We use the same machine and settings and the only difference is he uses an earlier version of Cura. I have also had this issue with files from multiple different developpers, indicating that it is not a file problem per se but more a problem with it's interaction with the software. Any ideas on how to fix this as it is a little irritating to have a massive print fail if I miss one small element on the bed?

2. This one is smaller and is likely a simple I'm not doing it properly. I have tried saving a "project" with a collection of STL files I will want to reopen at a later date, and after taking almost 5 minutes to save the project I am unable to reload the project or load the models from the project at a later date. any ideas?

Thanks for the help guys

It sounds like your STL files just have too many triangles. Consider reducing them somewhat with meshlab:

I usually keep it under 100k triangles but your mileage may vary.
