It has a stepper motor and most of your lower end cutters do.... I think there is a big myth in the industry that you need a big expensive vinyl cutter to get into the business when in reality you don't...
I can't comment about the US Cutter specifically... But Nicks statement that you must purchase a cutter with a servo motor to cut Rhinestone Material is simply not true...
You do not need an expensive cutter to get into the business. Cutters with Stepper motors can cut sign and heat applied vinyl just fine. A cutter with a Stepper motor WILL also cut Rhinestone template material, Twill, sandblast material and other "thick" materials. The big question is how ofter will you be cutting a thicker material like that?
If the answer is once in a great while, then you will probably be alright. If your answer is everyday, for instance, then you will most likely end up wearing out your motor sooner. Also, depending on the type of cutter you are using you may not see as good quality of cuts as you would with a better unit.
Is there someone out there that has a cutter with a Stepper motor that cuts thick material daily and has for years? Sure. I imagine that it could happen. I just advise people against it because there is a good potential to damage your cutter.
