Letters missing their middles
I'm trying to make a keyring for a friend and its absolutely doing my head in 😀
I'm not getting on with the filament (sunlu red and sunlu white) and it doesn't seem to stick to the bed particularly well (bed is soap and water clean) and it frequently lifts, but when it doesn't the finish is good!
But the biggest problem is that the middle of the letters doesn't print - I can't see anything obvious why it wouldn't - but then I am not particularly experienced!
Would one of you have a look and see if I have missed anything obvious? It shows as it should before slicing...
Thanks very much!!

This forum is awesome... I posted, decided to give it one more go (no changes, just another print off the SD card) and so far it appears to be working 🤣

Good to see it is working for you now.
I just started your print and it prints everything just fine here too.
The small parts of the letters will be the first to give you problems if you have any adhesion problems.
You could try bumping up the temp a little. The filament that I use should print at a lower temp than Prusament, but the Prusament profile works better for me.

For things like that. The LCD cover for the prusa itself is really very difficult in the same way. it has a lot of little dots of filament around the letters. I always slow the the print down to like 50% for that first layer to make sure everything gets laid down . After the first layer or two I manually increase the speed. This works well for me. I just printed the two of the covers in fact.

This sort of print really tests your first layer adhesion. Cleanliness and a well calibrated first layer Z are essential and @ssill2 is right to suggest slowing the first layer:
Print Settings > Speed > First layer speed
Try around 20mm/s
Cheerio,
