Can you give some examples 😅

I’ve had the same thing. I think orca’s retraction test is just too ‘easy’. I think the towers are too far apart.

You can’t trust what you can’t see.

This was it! I had my 10-25% (not degrees 😅) overhang speed set not to slow down at all. I now have it set to 30mm/s and I have a perfect result. Thank you 👍😁

Sorry, I didn’t follow that. Top layer of what? Not the actual top, top layer right?

You may actually be right even though I thought I had checked this. Orca’s overhang speeds are based on overhang percentage and not angle, I previously just looked at the number and assumed it was degrees 🤦‍♂️I will match the speeds for all overhang percentage ranges and see if that solves it 🤞

Thanks. I’ll experiment with temperatures first but I’ve got some different filament on the way too as it happens, so hopefully I’ll manage to escape the problem one way or another 😁

Thanks, I’ll give it a go.

It starts just underneath actually, but it still could be related 🤔 Maybe I need a test without numbers.

Thanks guys. I will try both and see what works. My layer adhesion is good / parts are strong though.

I was trying to avoid making it more complicated, but I might actually look into this anyway. It seems it might be a more tidy way to install them all together. Thanks 👍

— Thank you to everyone for replying. I’m pretty satisfied now that there is no trick to prevent grub installing unless an option is given during installation. Maybe in future, more distros will have the option 🤷‍♂️
