I only use my BSR in mode 2 because I prefer to stop and reposition my work and hands when the needle is stopped. There is a learning curve but I am pretty good with it.
I caution you with using rulers without the ruler foot. You need the # 72 so the ruler doesn’t slip under a low foot and the needle hits it. You could void your warranty and damage the machine if you hit a ruler. If you are using the #72 with the ruler foot......never mind.😁
