It’s troubling when it’s not really your area of expertise but the task requires an immediate solution. You’d face the same issue while looking for the best stepper motor driver for 3d printer.
Still confused? Well, the function of a 3d printer stepper motor is to usually place the extruder or to build the platform along the x, y, and z-axis during a task.
Moreover, an interesting fact about this best stepper motor driver for 3d printers is that they come in various proportions and sizes such as; NEMA 14, NEMA 17, NEMA 23, and NEMA 24, etc. The most precise 3d printer usually needs the best stepper motor driver for 3d printers to deliver ultimate precision.
Stepper motor is a brushless DC electric motor that plays a huge role in 3D printer functioning. It has the capability to divide a full rotation in a number of equal steps, which in turn is used to control the frequency and speed of the pulses. But to do this operation properly you need a stepper motor driver.
Stepper motor drivers have the ability to produce continuous contraction with precision. And this feature can be used even without a feedback system. These features are specifically designed in the stepper motor driver for the proper functioning of the motor.
These drivers are an important part of 3D printers. They are used in every type of printer. For example, stepper motors are used to move the extruder in the 3D printer, but it is stepper motor drivers behind the scenes that is regulating and control the speed of the stepper motors.
How do Stepper Driver and Controller Work?
Electromagnets play a major role in the working of the stepper motor driver. Electromagnets surround the rotor that is attached to the metal gear. Just like rotors, electromagnets also contain gear-like teeth structures. Both rotor and electromagnets faced each other but they both are not in contact with each other.
Apart from construction, the stepper driver and controller also play a role in the working of the driver. The Stepper driver and controller control the motor as it switches on electromagnets alternately. Pulsed waveforms pass through each coil and produce electromagnetic fields.
After that an event of changes will start occurring, gears will line up with the first electromagnet but not with the second electromagnet. The process will continue from one electromagnet to the other electromagnet. By this process, a single stepper motor can take at least 200 steps in one revolution. You can also reverse the motor rotation by changing the order of direction of energized electromagnets.
Type of Stepper Drivers and Controllers
Stepper motor functioning and performance are greatly dependent upon the type of stepper driver circuit is used. There are 3 types of stepper drivers that are explained below.
1. L/R Stepper Driver – Resistance Limited
The L/R stepper motor driver is a low-performing driver but it provides full-rated rotation. But this rotation is provided at a low to medium speed that will result in a limited range of power output.
This driver was the basis of the old drive designs and it was operated on the full and half-step mode operation. Also, this driver doesn’t have the feature to provide variable control of current levels, and therefore because of this, it will produce a system performance that lies in between low and moderate.
2. Bi-level stepper driver
A bilevel stepper driver has the ability to use both high- and low-level voltages. When bilevel uses high voltage, it will gain a high rate of current that is required to increase the rise time of motor windings.
After that, when the current level is reached to the required level the stepper will turn the supply of high voltage off automatically and will maintain the current supply from the low voltage. Because of this reason, it is known as bilevel. This feature of switching the low- and high-level voltage is the reason that this bilevel stepper driver is more efficient and produces lower costs.
3. (PWM) Chopper stepper driver – Microstep
This is the third type of stepper driver. PWM (pulse width modulation) stepper driver is also known as a chopper, constant and Microstep driver. unlike others, it used a single supply of high voltage and operates on that. For the regulation of an average level of current PWM, the stepper driver uses output transistors that are switched on and off automatically.
PWM offers both advantages and disadvantages. The most prominent and important feature that PWM contains is its ability to drive stepper motors in the Microstep mode. This Microstep mode provides the level of smoothness that isn’t offered by any other driver.
Microstep mode will regulate the current rate at all speeds. No doubt this feature offers excellent performance but it is more costly and complex than any other stepper motor driver. On one hand, this driver offers current boosts and mid-range stabilization but on the other hand, it contains some disadvantages such as the production of WMI and RFI. Also, another issue the chopper driver has is overheating.
What is Microstepping?
Some drivers contain advanced features in which instead of moving one gear at a time and taking alternate turns, the driver will simply apply enough supply of current that will hold the gear in between the steps.
Resulting in the increasing accuracy of the output. Nowadays, 1/16th microstepping is considered as a standard. But some drivers contain greater microstepping like, 1/32, 1/64, 1/128 and 1/256. The basic function of these microstepping is the same, but the driver with greater microstepping requires more amount of current to hold the rotation of the electromagnet gears in a fixed position.
Things to Consider Before Buying
Phases of Stepper Motor
- You can find two phases in stepper motor i.e. uni-polar which is a single-phase and bi-polar that is dual-phase.
- The driver depends upon the phases of the stepper motor as every motor is compatible with different phases.
- Stepper motors A5, 6, and 8 are compatible with Unipolar stepper motor drivers.
- A 4, 6, and 8 wire stepper motors are compatible with Bi-polar drivers.
Current Types
- There are two types of currents DC (direct current) and AC (alternating current).
- Most drivers come with DC in the market that is perfect for the proper functioning of a 3D printer.
- AC is rare but they are available in the market.
Voltage
- The stepper motor comes in different voltages.
- A traditional motor works at 2.8 Volts with a maximum current of 1.68 Amps. If it runs with a high voltage current then it will get extremely hot.
- A stepper motor helps in regulating the current flow. If it gets up to 12 Volts, it will start to draw more current.
Current Output rating
- There is also an output power outing range of the driver.
- The current output rating is given per phase and the rating shows the minimum output that produces in phase one.
- One important feature of the driver is the amount of current output determines the size of the stepper motor it can drive.
Current Adjustability
- The stepper motor drivers have the ability to adjust the level of power supply of the motor by adjusting the current.
- This feature is easy to use as it allows a manual adjustment to change the on-board resistor or adjustable resistor and will in return helps to choose according to the requirement.
Command Signal Input Type
- You can find different kinds of compound signals that can be found in the stepper motor driver.
- The most common input which is used for CNC is Step and Direction.
Step Modes
- There are different modes of operation like full-step, half-step, and micro-stepping.
- The full step is a hybrid stepping motor that adds up the strength of variable reluctance and the magnet permanent motors. It usually has 200 rotor teeth.
- The half-step operates the motor and rotates it 400 steps per revolution.
- The microstrip divides every step into 256 discrete that allow 51200 steps every revolution.
Driver Type
- You can find different kinds of drivers like L/R driver, bi-level driver, and (PWM) Chopper driver.
- PWM Chopper driver is the most common one.
Switching Speed (PWM drivers only)
- This feature is present in PWM drivers only and it provides the switching speeds.
- The PWM drivers instead of using step frequency use switching frequency for the operation of their functions.
- The minimum value that it must have is 20 kHz. Also, the higher the amount of frequency it contains, the more smoothly your driver will operate the functions.
Step Frequency
- The step frequency is the maximum input frequency needed for the compound signal.
- For a driver to operate its function properly a frequency of 0 to 200 kHz is needed. This amount of frequency is needed if you are trying to get high speed and accuracy.
Protection Circuitry
- The safety of motors and signal generators or computers is necessary and for this purpose, drivers offer various internal circuit protection.
- This required protection can be obtained by the use of optoisolators and fuses.
- If the driver isn’t providing such protection make sure that the break-out board does. Because if neither will provide one then the risk of harm will increase.
Idle Standby Feature
- This is an additional feature that is present in some drivers. Though this feature isn’t necessary it will increase the efficiency and life of the motor.
- The benefit of this feature is that after being idle for a certain amount of time it will reduce the power supply to each stepper motor.
