Please Note:

TMC2100 driver working temperature is more higher when working without the fan. current at around 0.5A working temperature is about 70 degrees, 1A working temperature over 150 degrees, is likely to lose step. advice to do a good job of cooling.suggest working current 0.5A.

TMC2100 Motor direction is contrary to A4988 and Drv8825 , if you want to replace them,please set the ajust firmware or adjust stepper motor wire connection.

Please do not connect to the motor while measuring voltage otherwise it may be easily burnt.

Please switch on the power supply instead of USB connected only while measuring voltage.

Please pay attention to the direction of the driver.

Please remove the 3 jumper caps first before you use on Ramps1.4 or MKS Gen.
