This Tutorial is for CURA Version: 15.04.2 (PC / MAC)
For beginner, let’s do Normal settings!
If your Ultimaker 2 had a long run time (2km+ filament ), the “fast print”might not work as well. Probably due to the old heating element.
Print all at once would build the object from bottom up all at the same time
Print one at a time would print one object at a time, then start another object in another area. This requires more space and the object can’t be too tall.
3d print warping. You can increase the heated bed temp by 10c
Ultimaker could print 90 degree overhang without support, but the surface finish isn’t great and the parts aren’t really all that useful. For 90 degree overhand I would check the Print support structure box
Depending on your design, you might not always need the support structure.
Form 1 Plus can print somewhat clear water tight channels.
This will happen when the your base is not sticking to the plate. Glue stick and higher temperature bed will help it stick.
