My plan for the TMC5161-EVAL-KIT by Trinamic is to confirm that the setup can accurately and repeatedly step to the required position. Secondly to look at the setup under stall conditions.
My first step was to get the software installed and do simple test to make the motor turn. The software was easy to install although flashing the development board took quite a few steps, the board needed and extra reboot which was not mentioned in the instructions.
The software automatically detected the board and it is easy to dial in different speed and acceleration profiles. Finding / calculating the correct motor voltage also took a bit of reading and calculation. There seems to be an inconsistency between "nominal coil voltage" and "rated voltage" and no explanation as if to these are the same. The motor produced a fair amount of vibration at higher speeds and it would be interesting to see if one of the other drive modes resolves this.
Although I have created a test rig consisting of an beam, angle brackets, bearing block and drum, I have yet to complete the two tests promised in my plan.
So hence this is a provisional report based on my findings so far and the score details are subject to change.
I will complete the positional accuracy and stall testing when I return from my vacation with the family.
Hope to have an update by 25th August.
