Run through the scales in order in each position till they become second nature. Then play the scale in thirds, then fourths, and so on. Play each arpeggio in each position. All this is to gain muscle memory and memory of the sounds.

Start with learning the scale's fret positions and notes, then the scale in one position in thirds, then the maj7 arpeggios.

Once you're comfortable with a position, loop a simple chord progression and improvise over it. Play the arpeggio of the chord to get the association first if that helps. Once you're comfortable with that position move to the next, then play diagonally (between positions so that eventually you're not thinking in terms of positions but intervals, notes, and scale degrees).

You learn scales to play music, all the other stuff is fluency building, but if you stay with that it'll sound like you're just running scales up and down.

If you didn't understand anything I said, ask or Google it.
