What error are you referring to? If you mean the red colour that is shown in this screenshot, that is normal. If you choose the "Line type" colour scheme in layer view, the shell will be shown in red.

supports do not come off properly

[gr5 2,235]

In 3d printing, if your support material is the same as your printing material then, that's pretty normal - supports do not come off easily and they will leave a scar behind.  Which you can sand or file off if you want but it's a lot of work.

 

However if you have a water soluble support material (or "breakaway" support) then support should come off easily.

And this is why people choose to get dual extruder printers.  Using PETG for support on a PLA model works because they don't stick together.  Using the same material for support as the model is always a head scratcher when it comes to supporting fine features like your headers over the doors and windscreen.  It's very easy to hurt the model when removing the supports.

Exacto knives, micro-files, and a set of picks or some used dental tools are necessary to clean up prints.
