hi 

 

though i registered a post in github tmc2209, i sumbit my issue in this community as well.

 

i using skr2 + tmc2209 in my 3d printer.

recently, my tmc2209 driver was damaged after printing over 24h, 35°C (stepper is nema 17HS3401, 24V)

then, i found that reason is short between GND and VDD.

to make sure it more accurately, i remove tmc2209 chip from BTT TMC 2209 module.

when i only checked tmc2209 chip, tmc2209 chip was short between GND and VCC_IO (VDD).

it mean tmc2209 chip was only damaged.

but i dont know reason of short.

it doesn't seem to be overtemp or overheat (just my think)

how can i know reason?
