Hello, I'm new to the forum, but I saw this post and wanted to offer this...

I've used Trinamic TMC2130's for several years now on my DIY 3D printer, so I can say with certainty that they will drive a 2-amp motor.  For your reference, here is the datasheet for the TMC2130 from Trinamic's website, in which they specify a 2-amp load is nominal with a 2.5-amp peak load.
