I recently bought a 4 head Tajima Embroidery machine and finally got around to finding time to have a Tech come by. He is going to check the machine out and give me a few hours of training/instruction. From you the experienced embroiderer, what would you put on your list of questions for the Tech. I know nothing and want to get as much info as I can out of this visit. He said he would show me the basics and let me mess with the machine a few weeks and then make another visit if needed. Which I'm sure will be needed.
