nisson20det,

Did you get the steppers moving yet?
All the other stuff is of no value if the axis won't move. ;)

Hi Friends,

Totally new to DIY-CNC and need your help and support to run my single motor in X axis (Pul/Dir).

I bought Rhino 10kgcm Nema 23 motor with DM542 stepper driver and trying to drive with 24VDC 14.5Amps power supply and 5 axis optical isolated board from Rrmin (Chinese make).

I did the connections as per general guidelines provided on internet, Everything seems fine but motor is not running.

Please support to figure out what is wrong and how to correct it

Which Chinese controller board do you have (make and model) ?

Hi Friend,

There is no model number for board, I bought it from Amazon (Rrimin Mach3 CNC Stepping Motor Driver Interface Adapter Breakout Board +USB Cable)

I worked again last night and by tuning motor control, I got the motor running.

My next query is how to increase the speed of stepper motor? How kernel speed affects it.

Kernel speed does NOT affect the stepper motor speed.

Thanx Roger, what other parameters/factors affect stepper speed.

Usually, stepper speed is set by the F command.
Note however that Mach3 can hiccup over this: you may need to repeat the command the first time.

Thanx again for valuable knowledge.
Please explain me how to fine tune motor control.
