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 😁
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.
When I do an overhang test, I always have this problem at about 35°. Does anyone have a suggestion what could be causing it?
- Slicer: Orca
- Layer height: 0.2mm
- Infill: 0% (this has improved it a lot, I think the infill was causing bulging)
- Outer walls: 2
- Overhang speed: 10 or 20mm/s (both look the same)
Solution: I mistakenly thought overhang speed in Orca was based on overhang angle, it is percentage instead (which makes much more sense for different layer heights). My 10-25% overhang speed wasn't set to slow down and that must translate to about 35° at 0.2mm layer height. I now have it set to 30mm/s and it now looks great 👍 And sorry, I was wrong when I stated the overhang speed 😅
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 🤷♂️
I use rEFInd as my boot manager and sometimes I like to dual boot a new linux distro (just to try out) which I install with a live USB. Unfortunately, after installing, GRUB has always taken the reigns and it becomes a slight inconvenience to get back to rEFInd every time.
Is there some trick that can request grub not to install?
[What prompted me to ask was I tried KaOS yesterday, and during installation it asked what bootloader i wanted and included the option for 'none'.]
