I'm currently using 0.9° steppers rated 2.4A with the TMC drivers on my CoreXY (300x200 bed). It's not a perfect combination, but my hotend carrier and the Y-gantry are not too heavy. I would go for 0.9°/1.7A steppers and 24V!
12V is the bare minimum for TMCs.

For a 32bit controller with plugin drivers, the RAPS128 are hard to beat. You can also run them on 8bit controllers, but with limitted microstepping ( 1/64 max. )

Thank you for your reply.
I will stay with 8 bit for now, so i need to use a 1.8º stepper motor...
I found a better fit motor, this one LINK.
I think that this one is better to use with the MKS TMC2100, because it has 1.5A. It gives me (85%*1.5) 1.27A, wich is closer of the 1.2A that the stepper motor shoud have with the MKS TMC2100 (this article (LINK) tells to select a motor with a current rating no more than 20% higher than the recommended maximum stepper driver current. This gives that the stepper motor shoud have about 1.2A.) If i ran the motor with 0.8A, then i will be using about 54% of the motor amp limit, which is in the OK zone...
Any advice is very appreciated.
