Heaven help me - I've just bought a delta kit :-)

[curious aardvark]

lol I have an actual official version of s3d. Reinstalled fairly recently
This is the only model that's crashed, also the most complex I've ever tried to slice, thinking maybe I need more memory in the computer.
Should be some on the shelf.

Yeah spends a long time 'initializing preview data' and then drops out. So probably memory related. I'll drop some more in and see if that makes a difference.
The fact that 'initialising' is incorrectly spelt with a 'z' could also be the problem ;-)

Doubled ram to 4gb - doesn't make any difference.

I will try and slice it with cura.

That works, must be my s3d install.
