Right Side MK8 extruder Aluminum 3D Printer Block

This is a high-quality MK8 Extruder Replacement Aluminum Alloy Block. Use it to replace your blocked/damaged extruder. This block comes in a kit form and requires assembly by the user. Since this is very popular numerous assembly instructions and videos are available on the internet which will help you build your extruder.

The MK8 Extruder is available in 3 different types – Right Side, Left Side and Right Short. These extruders differ in the direction in which the filament is extruded with respect to the extruder block. When using single extruders, any extruder can be used. When using dual extruders you can use one right side and one left side

This is a 26 Tooth Extruder Drive Gear that fits into extruder assemblies and firmly grips the 3D Printing Filament to move it towards or away from the hotend assembly. It is capable of high torque without damaging the filament, and fits directly onto the shaft of NEMA 17 Stepper Motors, making it simple to install but effective at assisting with consistent extrusion.

These particular Extruder Drive Gears are made for the All type of 3D printer extruders and ensure that the filament is moved into the melt zone when extrusion is happening while pulling it back when the hotend is moving across the print bed. This translates to smooth and consistent extrusion, with improved print quality, and reduces the chances of clogging or similar problems. Although this is a basic little part, it is a vital part of the extruder system and counteracts the back-pressure of the melted filament within the hotend assembly.

Typical Applications For The Extruder Drive Gear is for extruder Drive Gear is designed to fit the TEVO Tarantula, but could be used on many other similar 3D Printers, or even in different machines altogether. It is made from brass, which is durable but soft enough to prevent filament damage, and has a tiny form factor to easily fit without requiring any extra modifications.

The LM8UU 8 MM Linear Motion Bearing gives you very precise, safe and reliable linear motion system. Such linear motion bearings are mostly used in 3D printers and CNC(Computer Numerical Control) machines. An LM8UU 8 MM Linear Motion Bearing can provide low friction motion along a single axis, hence find a wide range of applications in DIY and robotics prototyping.

This is Aluminum GT2 Timing Pulley 20 Tooth 6.35mm Bore For 6mm Belt. For precise motion control, GT2 belts and pulleys offer excellent precision at a great price. This pulley is meant for use with GT2 6mm wide belts only – MXL belts will slip due to the different tooth profiles.

This pulley has 20 teeth and a 6.35mm inner bore. Two set screws can be used to attach it firmly to any 6.35mm diameter shaft. Full aluminum construction means these are very light and very durable.

This All complete Bowden V6 with Fan Cable 30cm Length for 1.75 mm filament 0.2 mm Nozzle contains the same signature high-temperature performance for high-temp printing, as well as increased functionality for printing soft and flexible filaments. This kit contains the old thermistor, heater block, sleeving, cooling fan with holder.

The v6 HotEnd allows you to print a wide variety of materials, from soft and flexible to sturdy and strong. This is possible due to the PTFE (Polytetrafluoroethylene) liner tube through the hotend that you can extend into your extruder – this gives the ability to add the confinement and constraint needed to make excellent quality prints with flexible filaments. This technology opens new doors for your 3D printing aspirations.

With High-Temperature Performance, you can print with high-temp materials like Polycarbonate and Nylon – this also eliminates HotEnd meltdown failures that are common with PTFE designs. Even though the v6 has a PTFE liner inside the hotend the liner is never subjected to high temperatures so there is no risk of damaging the liner through overheating. Basically, this design is really in-tune with all the elements, so your prints will come out crisp and accurate.

The v6 has cut back on a bunch of bulk. This clean-cut version’s overall length is only 62mm, and there are significant reductions in the X/Y dimensions by using the new injection moulded fan duct.

Are you eager to start printing right away? Good. So are we – and that’s why here at MatterHackers we praise the v6 HotEnd. No adhesives, Kapton tape, or soldering is needed to get started. The new v6 simply locks into place with a little screw, high-temp glass sleeving is used to insulate the thermistor legs. This makes installing the hotend (as well as removing) a quick and smooth process compared to earlier methods involving various adhesives. The parts of the hotend just screw together, and the fan duct naturally clips in – this can be manipulated in different ways to suit your setup preference.

An SC8UU 8mm Linear Ball Bearing Slide Unit CNC 3D Printer for use on hardened steel shafts. Ideal for small CNC applications as well as X / Y tables. The universal Ball Bearings is great for you to replace the damaged Ball Bearings in your devices to improve the efficiency and save energy.

Widely used in home appliances, industrial, low noise and high-speed electric motors, construction machinery, automotive components, pumps, and machinery. Smooth moving, low friction, high rigidity, and long life. Economical, easy to maintain replace.

CNC 3D Printer Mech Endstop Switch uses a lever switch to detect when it is activated. The switch is wired up so that when activated, it pulls the signal to LOW. There is also an LED on the board that will light up when the switch is activated. It uses a standard 4 pin 100″ pitch header and accepts a standard, old-style CD-ROM audio connector cable.

The mechanical endstop is a simple solution to a simple problem. We want to be able to detect when an X/Y/Z stage has reached its minimum or maximum. Instead of messing with flags or complicated light beam interruption, we use a mechanical switch.

If we place the switch in the path of the stage, then the stage itself will simply close the switch when it moves against it. Other than properly positioning the switch, we do not need to modify the stage at all. If you’re worried about reliability, you can sleep well at night. The switches we use are rated for 1 million operations before failure. Since we only use the switches once per print, that means you’ll be able to do one million prints before having to replace the switch

Connection description:

• Redline: connecting VCC (ramps of +)
• Black line: connecting GND (ramps of -)
• Green Line: connecting SIGNAL (ramps in s) 

This flexible type motor coupling can connect your driving shaft with the driven shaft while it is very efficient in eliminating any misalignment to the possible extent. Minimum backlash is another great advantage of this Aluminium Flexible Shaft Coupling 5mm x 5mm.

This Flexible coupling with the outer diameter of 19mm and the length of 25mm is machined aluminum coupling.

First bore diameter is 5mm and the second bore diameter is of 5mm also.

It comes with the spiral cut in the middle along its length which makes it flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects. Such couplings are also known as Beam coupling, helical coupling, Flexible coupling.

Some of the important features of flexible shaft coupling are,

1. Helical cut makes them behave like a springy in the X Y and Z linear axis but not in the rotational axis. That means that you won’t get more backlash, hence they are suitable for precision CNC work.
2. A coupling is a device which transmits power and torque. Couplings do not normally allow disconnection of shafts during operation. However, there are torque limiting couplings which can slip or disconnect when some torque limit exceeds.
3. By careful selection, installation and maintenance of couplings, substantial savings are possible in reduced maintenance costs and downtime.
4. It can protect the driving and driven shaft members against harmful effects because of misalignment of the shafts, sudden shock loads, shaft expansion or vibrations etc.
