Topic: Quick stepper. Quick stepper. Guys, A quick question or two if I may. I am just starting out with stepper motors and Im not sure about a couple of things.
The MAH driver allows for setup of the steps per revolution upto micro?? Should "steps" in the constructor be or whatever the driver is set to? Im thinking Id like steps per revolution and don't know if I should set steps to or At the moment I am only playing with the Arduino stepper examples. Thanks Jon. Re: Quick stepper. The regular Stepper library is not really suitable for a stepper driver that takes step and direction signals.
Use the AccelStepper library. For that type of driver it is also easy to write code that does not need any library. Two or three hours spent thinking and reading documentation solves most programming problems. Don't bother, you will need speed-ramping anyway, use AccelStepper in the first instance.
Thanks guys, much appreciated. I have downloaded the AccelStepper library and had a quick look through the documentation and Arduino examples. Based on my reading of the MAH manual and my current application, I don't think I need to concern myself about enabling or disabling the stepper.
Assuming the above is correctly wired, I now just need to figure out how to set the motor to a prescribed rpm - Im looking for 0 - 30rpm via a 10k pot at the spindle.

Likewise with ENA if it is needed. Both will probably work. Quote from: Robin2 on Dec 22,am.Hoping a basic knowledge of machining would help make prototypes and communicate with machine shops, he bought a small milling machine. Almost ten years later, he now runs NYC CNC, where he loves working with customers and machines for job-shop work, design-for-manufacturing and product development. A largely self-taught machinist, he shares many of his endeavors on his successful YouTube channel which focuses on home shop manufacturing.
For more information, see www. Any stepper motor is great, but the big ones are amazingly impressive. There are numerous stepper drivers dedicated for use with Arduino, but they are generally limited to Nema 17 and Nema Luckily, using larger steppers Nema 34 in this instance with Arduino is still easy. In these two videos, we walk through the setup of the motor, driver, and Arduino. In this video we test code from three different Arduino programs to drive the large NEMA 34 stepper, then increase the load on the shaft to see how the stepper handles the additional weight.

Please post a link to its datasheet or schematic. It should be possible to connect the Leadshine driver to an Arduino without any shield.
The Thread stepper motor basics may provide some background info. Two or three hours spent thinking and reading documentation solves most programming problems.
Thank you for your reply Robin2, This is the schematic of the leadshine M driver. Test equipment, replica and original sci fi props and costume pieces, and whatever else I feel like at the time. I have an Ultimaker and a 3D engraver. I'm not sure why you bought a shield that is meant to have the A driver board plugged in to it, with a totally different stepper driver.
But- See where it says "Step" on the Protoneer shield? Ground all of the Pul- Dir- and Enable. If these breakout boards are not suitable, please suggest a suitable one for my use.
I need to drive 4 nema 23 stepper motos using 2 motors for y axis with a peak of 3 amps each. Below is the link of the instructable. What breakout board would you suggest me to use? Could you name a model? For the leadshine M driver?
It should also fascilitate a display Yeah but i was thinking of something with better quality. Anyway thank you for helping me out.I think the code is feasible except a an error. Well spotted. I did test the code before sticking it on here and it worked fine.
I have edited my original post to include this correction. I am trying to use this code with three stepper motors followed by each other for a warehouse unloading process. But somehow it keeps working on the same engine and doesnt want to move the second stepper motor which is plugged in at It seems like that you have just define two stepper motors in the code instead of 3? Could you possibly take a photo of the wiring ro explain how you have wired the two motors and controllers?
Hi dalbymanyou can visit the Instructablesstep 17 to know how to connect the cable with two stepper motors and controllers. Thanks Johnny, but I was asking how Ehsan wired it so I could help him with the code - just in case it was wired incorrectly.
Ehsan UTC 4. Hello guys, I am trying to use this code with three stepper motors followed by each other for a warehouse unloading process. Johnny UTC 5. Johnny UTC 7.
Johnny UTC 9.I've seen a number of tutorials about how to build the platform for a 3-axis CNC milling machine. I have not seen anyone tackle the tricky subject of the electronics. Here now is my attempt to do so. Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson. TIP : Don't get a 6ft or 10ft Cat5 cable. Buy your cat5 by the foot from any computer or electronics store. That stuff has one wire inside instead of lots of little fibers. Little fibers are a huge pain to work with. This will cause permanent damage. Then slide the cover down and over the soldering.
TIP: Don't forget to have everything disconnected while you solder! Solder the positive and female lines to the female plug. Double check you didn't wire the board power to the stepper power. That would be bad. Do you have a multimeter? This would be a good time to check your connections. Plug in the power. Now the wiring is done, time to test it with some code. If you put the stepper on a hollow flat surface like a desk top it will sound like a tiny formula 1 race car. Any faster the motor stalls.
If everything worked right, you should have three steppers each moving at different speeds back and forth. There should be a light on each EasyDriver showing that it has power. If you have a light and no movement, You might not have a good connection to your arduino. So what next? Now that you have three motors working through the arduino you can use the serial interface to tell the arduino what you want the steppers to do. By changing the different motors in the right pattern you can interpret G-CODE and start cutting patterns.
The biggest choice you face is what to cut! Thanks for reading!
Today I bought a stepper motor to play with, after 12 hours of struggling with it, I haven't been able to figure out how to connect it to an Arduino. Wires are colored: whiteblueredyellow. All the pictures and circuits of easy tutorials I found on Google had 5 wires, and those with 4 wires had different color coding anyway.
How to Wire an Arduino-based 3-axis CNC Machine
But a 4-wire doesn't make sense! Because I forgot to buy one, and I can't get my hands on one for a couple of days. And this is exactly the source of confusion: On arduino website, the sample circuit's stepper has 4 wires and is directly connected to a driver IC a LMxxxand the driver is connected to Arduino. Since I do not have a driver at hand, I need to convert the circuit so it works with 4 transistors instead. But what the wiring should be?
If it had 5 wires I would have done it like this schematics. Your motor is Bi-polar. It has two windings and you need to use a circuit that constantly inverts the polarity of the supply to the coils.
This is done with an H-bridge that operates as four switches. You need one H-bridge per coil, so you'll need two of them to control your stepper.
In practice these switches are either mosfets or transistors. Unipolar ones are much easier to work but more expensive to make with as it's just a matter of turning the right coils on and off in the right order - so most simple tutorials are for those. Bipolar ones, though, require a pair of H-bridges to get them working properly. Not only to you have to turn the coils on and off in the right order, but you have to switch them to the right polarity at the right time. Sign up to join this community.

Nema 23 driver for RPM. I should change the speed through a potentiometer with range 0 - RPM. I can change the speed with this program : Code: [Select]. Re: Nema 23 driver for RPM.
Stepper are not that grate at going fast. I don't have problem with the money because I already have the Nema 23 stepper motor. I just wonder If I must buy another driver.
It may not even be possible to achieve rpm with that motor and power supply, but the higher the motor power supply voltage, the better. Are you using full-step mode? Have you properly adjusted the current-limiting feature of the motor driver and if so, to what value is it set? Try this very basic test code. Note that the pulse is very short and all the timing is between the pulses. Code: [Select]. Two or three hours spent thinking and reading documentation solves most programming problems.
Quote from: jremington on Aug 19,pm. The voltage should not affect the speed, apart from enabling but not causing higher speeds. Speed is only determined by the interval between step pulses. Have you everything wired up correctly? Mis-stepping is usually caused by resonance, an unloaded motor will behave differently to one under load so firstly test the motor under its actual mechanical load.
Note the driver you has an abs. A good NEMA23 motor would be 0.
