Product information JG Performance MKII "Kit"

The "JG Performance MKII" upgrade offers Auto Bed Leveling and significantly increased cooling performance in combination with our "HD Tube 1.9", which significantly reduces the tolerance of the original Bowden Extruder system with an inner diameter of 1.9mm instead of the usual 2mm. This allows more precise retracts while reducing the changing clearance at large X axis movements, which helps reduce stringing and blobs.

The JG Performance MKII Kit consists of the following components:

HD Tube

HD Tube 1.9

Precision 1.9mm PTFE Bowden Tube made in Germany.

• Precise material feed

Precise feed control helps reduce stringing and blobs.

• Lower retracts

The reduced clearance in the Bowden reduces the retract lengths while saving valuable printing time.

• Excellent sliding properties

With a coefficient of friction against steel dyn. Dry 0.05-0.1μ and a Shore D hardness of 65, our HD Tube is ideal for printing all common materials.

• High temperature resistance

The melting point of the HD Tube is 326°C, which makes it easy to work with print temperatures of up to 260°C.

JG Height Sensor MKII

JG Height MKII

The heart of the JG Titan MKII upgrade - the mechanically height-adjustable "JG Height MKII" IR height sensor by David Crocker.

• Calibration without G-Code & Scripting

The height adjustable by an aluminum wheel IR sensor can be adjusted by + -5mm in height. The only thing you need to do is bring the Nozzle to the bed at a height of 0.5mm using the Z-axis method. Then the height sensor can simply be adjusted by turning the adjusting wheel until the red LED indicates contact.

• No temperature-related tolerances

The IR sensor is temperature insensitive to most other sensors available on the market and always delivers constant values compared to induction sensors. Thus, printing at different room temperatures or extremely different pressure temperatures without recalibration is easily possible.

JG Cooler MKII

JG Cooler MKII

The temperatures are always under control with the "JG Cooler MKII" Radial Cooler System.

• Extreme cooling performance

The high-quality 50x50x15mm Radial Cooler from the company Xinyujie with fabulous 0.2A and a maximum speed of 6500UpM can, if necessary, build up a pressure of up to 30mmH2O. The 30x30x10mm Xinyujie heater block cooler has an output of 0.15A which represents an increase of 200% compared to the original cooler and allows printing at temperatures of 260-300c with "Full Metal Hotend" * (* optional).

• Auto Restart function

Both coolers have an auto-restart function which restarts the fans at low speeds in case of a standstill.

• Backwards compatible

The "JG Cooler MKII" has the original connection for fan ducts. Thus you can use all fan ducts available for the A5 and A3S.


(included in "JG Cooler MKII")

The 360° all-round cooling for absolutely even object cooling in every direction.

• 360° Cooling

The uniform cooling in combination with the "JG Cooler MKII" ensures optimal cooling even at high printing speeds. This enables flatter print angles and more precise overhangs when printing with material such as PLA.

• Freely available STL download

You can freely download our JG F-Duct MKII from Thingiverse and print it yourself if needed.
