i have leadshine stepper motor driver dm542e "2-phase stepper motor drive to control stepper motor . but i have problem in Dip selection switch. choosing different compination of the Dip leads to hot motor and noise with difficult motion. so i think there is a special configuration. i use power supply 10 A
my stepper motor specs is mentioned in the first post , its model
I use the same set up.
Try these positions. Switch 4 is half current or full current, I suspect this is one to check.
ON: 1 2 5 8
Additionally, please post your code

this configuration doesn't work with me.
ALL stepper motors get hot when they are holding position. Too hot to hold your hand on it is the only time it is TOO hot.
Did you Ohm out the coils to make sure that you know how to wire to the driver?
Post a photo of our wiring. please.

it's hot i can't hold my hand more than 5 seconds. i measured coils ohm it is 2 ohms connected in series
Have a look into your motor data:
Temperature rise: 80°C, rated current, 2 phase on
With an ambient temperature of 20°C you will get 100°C motor temperature. How long will your fingers withstand that? The motor can withstand much higher temperatures than your fingers.
If you don't need the full torque of the motor, it's a good idea to set a smaller motor current to achieve a lower temperature rise.

when i set lower current it makes tic tic without spining, the motor temperature is around 50C
Hi,
Can you post a link to data/specs of your stepper please?
Thanks.. Tom...

at stationary position i put my and on the motor i feel tight motion of gears but the shaft is stopped
– Step Angle: 1.8°

yes i connected it series ,but the colors are different in my case

this is a basic code,and the motor working according to this code but with heating problem and tic tic
Hi,
Can you please tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom...
