Stepper driver change for no-noise bot

[Ascend]

@eide

Also the voltage is not higher than 1.1 V - not sure if I can set it all the way up to 1.9 V as with the old driver (and if that would create better torque)

1.9 Volts sounds like a dead driver soon. My drivers are set to 0.8 to 1V, can’t even go much higher, because my motors start to stall when its set too high.
My TMC drivers are in duty since december (1/2 stepping) and I havent had any issues yet with overheating or similar and they are not cooled yet. But my electronics box is not in the direct sunlight what could be a big difference.

@eide

Does anyone know (is there a tradeoff between torque and microstepping?)

There is, as Loveny approved in this post.

Thanks for sharing your experiences and also thanks for sharing your information sources. This might be really helpful if someone wants to change the drivers as we did .
