HESAI DRV8825 Stepstick Stepper Motor Driver Module + Heat Sink for RepRad 3D Printer RAMPS 1.4 Controller Replace A4988 (Pack of 5 pcs)

Description:

The DRV8825 stepper motor driver carrier board TI DRV8825 micro bipolar stepper motor drive is a breakthrough. The module has a pinout and interface with our A4988 stepper motor driver carrier is almost the same, so it can be used as a better performance of the pull-down menu board replacement in many applications. DRV8825 features an adjustable current limit, overcurrent and overtemperature protection, six micro-resolution (down 1/32-step). It uses 8.2 – 45 V, can provide up to about 1.5 per phase no heat sink or forced air flow (rated up to 2.2 per volume sufficient additional cooling).

Feature:

A simple steps and direction control interface

Six different steps resolutions: full step, half step, 1/4-step1/8-step1/16-step, 1/32-step

CAN interface directly with 3.3 V and 5 V systems

Over-temperature thermal shutdown, overcurrent shutdown, undervoltage lockout

Short to ground short circuit load protection

4 Layer 2 oz copper PCB, in order to improve heat dissipation

Exposed solder ground below the bottom of the driver IC on the printed circuit board pad

Module size, pin and interface matching A4988 stepper motor driver operators in many ways

Adjustable current control lets you set a potentiometer, which lets you use the stepper motor\’s rated voltage or more, in order to achieve a higher rate of maximum output current step

Intelligent chopping control automatically selects the correct current decay mode (fast decay or slow decay)

Maximum 45 V supply voltage

Built-in voltage regulator (the need for any external logic supply voltage)

Package List:

5x DRV8825 Stepper Motor Driver

5x Heatsink

1x Screwdriver

Product Features

  • This DRV8825 Stepper Motor Driver Module is upgrade of A4988
  • Simple step and direction control interface
  • 4-layer, 2 oz copper PCB for improved heat dissipation
  • Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
  • Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates

3D Printer Accessories Automatic Leveling Module Film Pressure Probe Type Auto-leveling Sensor for E3D V6 MK8 Makerbot Nozzles(For Makerbot Nozzle)

SPECIFICATIONS:
Compatible nozzle(Optional): For Makerbot, for Ultimaker, for MK8, for E3D/ E3DV6
Weight: 12g
Signal line: 1m/39.37inch

AUTO LEVELING PARAMETERS DESCRIPTION:
1. X-axis direction offset: the offset of the leveling probe relative to the print nozzle in the X-axis direction
2. Y-axis direction offset: the offset of the leveling probe relative to the printing nozzle in the Y-axis direction
3. Z-axis direction offset: the distance from the platform to the print head when the leveling probe detects the platform
4. Probe stowed angle: the angle of the servo for the leveling probe when the probe is stowed/retracted/up (can ignore this when not in use)
5. Probe open angle: the angle of the servo for the leveling probe when the probe is deployed/down (can ignore this when not in use)
6. Number of leveling points: The number of probe points that probe on the plane. The actual number of detected points is equal to the square of the set value. For example, if set to 4 points, 16 points are actually detected, and the maximum is 9, namely 81 points.
7. Probe trigger mode: Set the level state when the leveling probe is triggered.

PACKAGE INCLUDED:
1 x Auto-leveling module
1 x 1 meter signal line

NOTE:
Do not use the leveling sensor when the nozzle temperature is higher than 45 degrees!!!

Product Features

  • Easy to install, can be applied to different types of 3D printers. Plug and play, the default trigger distance is 0.1mm
  • High precision, leveling adjust accuracy can be up to +/- 0.05mm
  • The average service life of the module is more than 500,000 times
  • Compatible with almost all the 3D printer motherboards in the current market
  • Good anti-interference ability, will not be affected by the platform material, ambient light, ambient temperature and humidity, etc

ARQQ Heat Bed Mosfet Tube Hot Bed Power Module Expansion for 3D Printer Heating Bed Accessories(Pack of 2)

Details: Dimensions: 60*50mm
Net Weight: 40g
Color:Black
Max Current: 25A(Enhance heat dissipation)
Wire’s color is random

Summary:
1. Remove basically all ouside screws for your anet a8 control box
2. Take pictures of existing board wiring
3. Unscrew two large 12/14GA wires on the board labeled “hot bed”
4. Screw these two wires into the new mosfet board labled “hot bed”
5. Connect the small jumper wires (white) to the control board where you just removed the two wires and screw them down. Note the polarity on each board. Match (+) to (+) and (-) to (-)
6. FInd 2x 6-8″ pieces of 12 or 14 AWG wire. Most cheap extension cords are 16AWG (too thin). Your local home depot / menards / ace will have this as cut-to-length
7. Run one of the 6″ wires to the power supply (+), screw in; and the other side to the (+) DC IN on the new mosfet board. Repeat for the negative wire (-) to (-)
8. Many people use velcro to secure the new board to the top of the control box. Others print off a holder from thingiverse
9. Put everything back together
10. When complete, you’ll see a blue light activate for signal from inside the box when the bed heater is activated by the control board

Package Included:
2xHot bed MOS Tube Power Module Expansion

Product Features

  • Work with anet a8 3d printer heat bed
  • Completely solve the hot bed power is too large and the load current issue
  • Under the premise of normal cooling, it work stable under I(Max)=25A, the current must not exceed 25A while the process working
  • General Add-on Heated Bed Power Expansion Module
  • Note: Any issue please contact us before, we will always here to help!
