Solve the drawing
Retraction is accurate and can be adjusted to a higher speed,
Test setup-PLA ABS hard filament: Retraction speed (mm/s) 25-30 distance (mm) 6-8
Flexible filaments such as TPU need to be re-adjusted according to different materials.
Compatible 3D Printer

Far distance Mounting Plate
OMG ID:F42
Suitable for standard 20*20 aluminum profiles.
CNC aluminum
This mounting plate is not necessary. Some machines can not be used, such as ENTER 3 V2.
Installation
Pay attention to the stepper motor gear and tighten the screw position to prevent interference with the reduction gear. Correct as shown below.
Direct Extrusion installation
Adaptation for Close range，We will continue to increase the adaptation and installation accessories, suitable for different models.
The following are some of the adapted parts
ID:M6A （TC4）
Titanium alloy material. TC4
M6 threads at both ends, transparent Teflon tube inside the middle through hole, you can observe the filament, and it has no heat conduction.
Features: Between the hot end and the heat dissipation connection: working temperature -100 ~ 550 (℃)
The strength of TC4 sb=1.012GPa, the density g=4.51g/cm3, the specific strength sb/g=23.5,
The thermal conductivity is 1/5 that of iron and 1/10 that of aluminum. The thermal conductivity of TC4 is l=7.955W/m·K.
ID:TC4-04
Material: Titanium alloy nozzle, diameter 0.4mm
ID:TC4-H2
Material: Titanium alloy hose, Teflon is not directly connected to the heating block. Avoid high temperature Teflon hose melting.
Heat dissipation is E3D v6 M7 thread
Hot end M6 thread
ID:10M6
Material: Stainless steel

OMG V2-S upgrade instructions
1/ Change the color to silver-sandblasting oxidation treatment.
2/ The gear diameter of the V2-S upgraded model is adjusted to 8mm, and the arc of the filament is increased.
(V2 old gear diameter 8.8 is not compatible with V2-S)
3/ Added 2 options of steel gear and copper gear.
4/ Added support for BL automatic leveling and 40 cooling fan mounting holes.
If you need OMG V2 old gears. We will continue to provide supporting support (only copper gears).
3D Step file download:
//github.com/my3dltd/OMG-V2-S
V2-S style extruder-the concave arc of the filament gear is larger, which increases the contact area with the filament.
The position of the filament through the positioning hole is different, and the gears of V2-S and V2 are not universally compatible.
