I am new to Arduino and want to use a uno board to control a 3-axis cnc machine. I’ve bought nema 23 closed loop stepper motors together with CL57T drivers. My problem is how do I connect said driver to the uno? I’ve searched high and low on google to no avail. Surely there is someone who knows the answer to my dilemma, or even point me in the right direction.
So that we can understand your project, and then be able to help you, help us by providing information about its components.
Link or photo and model of your motors;
Link to your drivers;
Which Arduino are you using in your project?
Are you using some other board besides the Arduino and drivers, etc etc....
A good project schematic would be well received.
Hi ruilviana,
Thanks for your reply and offer to help.
My motors and drivers were bought from stepperonline, namely Nema 23 closed loop 3Nm and the drivers are CL57T-V41. They are powered by a 36 volt power supply rated at 800w.
My Arduino UNO is R3 which has GRBL 0.9 flashed to it. I’ve connected one motor and driver together and powered it up. I’ve also connected the driver to the Arduino in the following way;
PUL-, DIR- and ENA- have been looped together and connected to pin GND.
PUL+ to pin 5
DIR+ to pin 3
ENA+ to pin 13
When I connect my laptop via usb and click on connect machine, I am notified that the connection has been made. However, when I use the “jog” control buttons (x,y and z) there is no response from the motor even though the symbols on screen suggest it is moving. I’ve tried reversing pins 2 and 5 but that doesn’t work either.
I hope this information is useful to you and enable you solve my problem. Do not hesitate to request any further information if required.

here's what I can find:
for V4.0:
for V3.0:
I do not work with these, so I gave you the datasheets or "manuals".
from where are these coming from?
Did you switch the input settings to 5V? Factory setting for these drivers is 24V.
Thanks MicroBahner.
I’ve just changed that setting to 5volt and now the motor moves using the x axis buttons in UGS.
Thanks to everyone who replied. Now I can proceed with buying all the other parts for my machine.
so everything else seems to be ok
