I am totally new to arduino and electronics world. I am kind of stuck with a project that I will have to deal with electrical Engineering and control. I am not familiar with this kind of coding, but I am trying to learn. I have read the essay about stepper motors on this website and it was useful.
Currently, I am trying to control one NEMA 42 stepper motor with driver as in links below. I followed the the connection and the code in the link below which worked but has nothing to do with my application. For this motor, I am trying to make it rotate at high rpm (let's say 1000 rpm) clockwise to drill. I would like to monitor the rpm and the torque of the motor.
Further, I will be using another stepper motor with linear actuator to lift this motor and the rest of the drilling assembly. I would like to count the distance the assembly moved on the linear actuator. I might use a small DC motor for a specific drilling application further on.
To sum up, I am trying to run the first stepper motor at high speed separately. Then I would like to run the second motor with linear actuator.
Please read the first post in any forum entitled how to use this forum. http://forum.arduino.cc/index.php/topic,148850.0.html .
Then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Robin2:
Stepper motors are designed to provide very precise movements, not high speeds.
...R
But can't stepper motors achieve high speeds? It would run on high speed for some time, then I would need it to take small steps while the DC motor runs.
The application I am doing is a small drilling rig. The following link can be help understanding what I am trying to do.
On more question, how can I be notified if someone replies to my post or a post I want to follow.
One more questions:
How can I be notified about the replies to my post or a post I want to follow?

That depends. It generally requires a high voltage power supply - maybe 60v or more - to overcome the inherent inductance and back emf.

I believe there is a setting in your Profile but I have never used it. If you visit the Forum to check if there have been replies to your question it gives you the opportunity to view other Threads where you may be able to help someone else.
If you are making a drilling rig choose a normal DC motor and gearbox .
As said steppers can’t run fast , and you need hi rpm for small drill bits .
Unless large a stepper has little torque too.
