The problem with TMC222 is they are independant and run on I2C. This makes em useless for cooperating when you want to move multiple axis at the same time in a controlled manner.
There is only a limited ammount of speed steps available in the tmc222 so only certain angles of motion will be possible when controlling multiple motors.
Using step/dir based controllers is really highly recommended for a cnc so that each motor can be fully controlled and all the drivers synched.
I'm interested in your project. Could you give me more informations about tmc222 controlers? schamatics etc... I made cnc router and now I'm thinking about controllers. I have tmc222 chips and I dont know how to use if programs using dir/step outputs. thx for help
