Note: The colour of the PCB may vary according to the Manufacturer HOW TO CONTROL STEPPER MOTOR The step motor is to a machine to convert pulse to angular displacement. So if you give stepper driver a certain pulse signal, it will drive stepper motor to a certain angle. you can control the angle the stepper moved by the number of the pulse. And you also can control the speed of the stepper rotate by the frequency of the pulse. The following picture is the schematic of the stepper driver. The following picture is the control signal to drive a 28BYJ48 stepper to rotate 1/4096 circle.

Ultra-silent 4-layer Substrate MKS-LV8729 Stepper Motor Driver with Heat Sink The Ultra quiet LV8729  4-layer Substrate Stepper Motor Driver Module with 128 subdivisions is used in 3d printers and is a Best suited Moter Driver for Nema stepper motor whose current is less than 1.5A, which makes the motor steady, quiet, and precise. The LV8729 is a PWM current-controlled micro step bipolar stepping motor driver. This driver can perform eight times of excitation of the second phase to 32W1-second phase and can drive simply by the CLK input. It has a wide range of Operating voltage range i.e. 6V-36V, the proposed voltage is 12V Support subdivisions of 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 with product Process of four-layer PCB board. In the 64 subdivision or 128 subdivision controller, it has a better ultra-quiet effect. Note: Please make sure the connecting direction is right, or it will probably burn the driver chip and controller board. Recommend doing a good job of cooling the module Driver current algorithm and its adjustment : Driver current algorithm: i=Vref/0.5, the default Vref about 0.4V, so the default current 0.8A, and maximum current 1.5A Please DO NOT connect the motors when measuring the voltage, or it’s easy to burn the drive. Please connect both the power supply and the USB for power when measuring the voltage. Minor adjustment for potentiometer driver. Adjust it again after measurement to avoid burning the driver by excessive current. To increase the current by rotating the potentiometer clockwise slowly, and anticlockwise to reduce.

V6 Bowden Heat Break Hotend Throat Without Teflon Tube for 1.75mm Filament This is a V6 Bowden Heat Break Hotend Throat Without Teflon Tube for 1.75mm Filament. This is a heat break compatible with the E3D V6 hot end for a 3mm filament.  It comes with a PTFE insulation tube on the inside.  The heat break has a shoulder on the top to ensure that the PTFE tube does not move up inside the heat break. These are high-quality stainless steel sleeve tube caps that are ideal for use with 3D printer extruders that use 1.75mm filament. They can be used for a long time without any issues. This part will eliminate the PTFE liner and give you good, long-lasting performance with PLA. The V6 Bowden heat break is used to channel filament through the cooling tower and straight into the heated nozzle. The top end of the heat break inside the cooling tower is designed to stay cold while the bottom end inside the heat block will heat up which in turn will aid in rapidly heating up your filament to the desired temperature in preparation for extrusion through the nozzle.

V6 Volcano Brass Length Extruder Nozzle 1.75mm x 0.4mm V6 Brass Volcano Nozzles are High-performance brass nozzles for your Volcano HotEnd. From super-fine to super-fat layering, you’ll be making stronger, faster and bigger prints in no time with the Volcano HotEnd PowerUp! These nozzles are immediately compatible with the Lulzbot Moarstruder, but many RepRap 3D printers including the Prusa i3 can be upgraded with a Volcano. Volcano nozzles are super fast printing nozzles for use with the Volcano block and packs to print large layer heights and at extremely high flow rates. V6 Brass Volcano Nozzle has extra long heated melt zones for ultimate filament melt speeds. Volcano nozzles are designed with speed in mind. They excel at large layer heights with extremely high flow rates which can reduce your print time. All volcano nozzles are marked so that you know exactly what size you are working with. The nozzle has a longer heated zone when compared to most hotend nozzles. This means that the filament is heating slightly faster, therefore it has accelerated melting speeds. The brass Volcano nozzle performs excellently with non-abrasive filaments such as PLA, ABS, PETG, Nylon, ASA and TPU. Due to the special shape and the low coefficient of friction, no filament residues remain on the inside of the nozzle, even with extremely long printing times. Due to this low resistance, an optimal flow is achieved that ensures the perfect extrusion and therefore an undisturbed 3D printing process. Note: Volcano nozzles are only compatible with the Volcano block.
