ok, sorry , completely new to this . I change those setting by the config file right. Any starting suggestions?here is the current on default config:
#Drive current
>CURRENT_VREF_XY 1000 #Default motor current for XY in mA??range (0~1000)
>CURRENT_VREF_Z 1000 #Default motor current for Z in mA??range (0~1000)
>CURRENT_VREF_E 1000 #Default motor current for E in mA??range (0~1000)
