With some colours in PLA the print sticks tight to the raft and removing it can damage the print. Black is my nemesis, which is a shame as my favourite colour but I then had a similar issue with a red from a different brand.
Reading up, some folks say 1) skip the raft, some say 2) lower the bed temp, 3) raise the extruder temperature.
1) Skipping the raft meant it didn’t stick long. Is this a skill worth practicing?
2) Lowering the bed appeared to be better, until adhesion broke on an identical print and ruined it.
3) Raising extruder temp made no difference until the product was too hot.
Any tips from the experts.
As a fellow Adventurer owner, I found that ensuring that you check your levels every couple of prints makes a great difference.
I set it so that the paper between the nozzle and bed just grips, then go one increment up. That seems to give me the best results for both adhesion and removal of the print.
If you get lifting/warping of the print lower the nozzle 1 increment.
I've never noticed a great deal of difference when changing the bed temperature - but if you're printing in PLA keep the door open. If printing in ABS keep the door shut.
The manufacturer of the PLA makes a difference, but can only be found out by trial and error.
I guess that different colours have similar different properties, due heat absorption/radiation being different, but again experiment a little - and keep notes.
Cleaning the print bed with an alcohol wipe also seems to make a huge difference. I have used a wallpaper scraper to clean the bed of all residue, but found that it reduced the 'bumpiness'
of the bed resulting in reduced adhesion. it also caused a few divots, which transferred over to the print, so proceed with caution.
You can save different configurations in the slicing settings (and name them differently) so you don't have to keep changing each setting manually.
Raft settings are easy to change in the slicing menu, but I've had difficulty removing the raft from the print on a lot of occasions with default settings, so rarely use a raft.
