The range of steppers is wide and of course the price you have to pay for these So we decided to get some from ebay(to save money for important think like the communication and I think after the arrival of the ordered one that this wasn't a bad decission But how to controll them First I thought about using a microcontroller and some drivers But why concentrating on this things for a long time if there are more interesting things So we decided to use a combined controller+driver from Trinamic Therefore I ordered the TMC222-SITMC222-SI that arrived yesterday Now I'm curious about trying them
If someone has any experience with this Trinamic chip, I would be very glad if he/she posts them as a comment.
