Great advice!
I too have just started using a laser with pantographs and have just kept practising.
I wondered if the stylus (Pattern Perfect)would be easier and whether the product is still sold as the Qbot is nearly AU$7,000 here and way out of my league.
I also practised a bit on free motion and tended to find that a little easier on the frame.
Not perfect yet and no expert but noticed that I am getting better at it.
Keep practising (I felt it was a lost cause and disheartened but didnt give up) and am getting better with each practise run.
