Hi all, a very simple print is showing an odd error. It’s simply a rectangular plate, 3mm thick, with two holes near one shorter edge. It’s not a complex mesh, according to netfabb and makeprintable and any other checker I can throw at it, it’s got no errors. When printed, on the final top layer, the printer appears to simply “forget” to finish a couple of sections (see image - I haven’t used a photo 'cos it’s virtually impossible to see). This is a screenshot of the final layer in Simplify, which shows that the layer should be complete and even.

However, when printed, it misses the bits I’ve crudely highlighted in red. It’s just as though the printer has forgotten to go back and fill these missing parts in. It’s only on the last layer, all previously layers - including the previous solid layer beneath, were fully completed.

Any ideas?

I have not seen this before. Can you post the STL so I can play with it?

Sure, thanks guys. Posted. I have to admit there’s a substantial possibility I may have screwed up somewhere; I’ve just run it through netfabb again and this time it changed the file size. Anyway, if it’s not any trouble, I’d appreciate any help offered.

BTW, there’s no need to print at full size - I saw the same problem when printing at 60% of full so you could save some filament…

I’ll try this afternoon when I get home. What printer and material did you use?

Hi @wirlybird this was PLA on my FF Pro. Please don’t go to any trouble, I’d like to try this new version myself but can’t until I finish a longish customer print…

Not yet, been busy with customer prints. Probably won’t try it again until my PEI sheet arrives…
