Ortur Laser Master II - Air Assist

thingiverse

All right, there are a lot of Air Assists for the Ortur Laser Master 2, I printed many but none worked for me, they all caused interference while homing with either the X coupler or the frame. The only option was to pass the tube below, behind and around the X axis / X carriage. So I designed this. <strong>Extra considerations</strong>: <strong>a)</strong> I also wanted the ability to easily adjust the area of focus for the air assist, so the "white tube" has 2 axis of motion, and can be locked in place with the M3 knob (FYI, the nut goes on the outside) <strong>b)</strong> And, i don't really like the idea of having something rigid so close to the workpiece, as such this "white tube" is slightly flexible, as such if it does hit the workpiece the air assist wont get damaged or cause a hard stop. <strong>Notes</strong>: <strong>1)</strong> I used a OD6/ID4mm PTFE tube (very rigid) in the assembly and connected it with a OD6/ID5mm aquarium tubing (very soft) for routing it alongside the cable bundle. <strong>2)</strong> To print in TPU: Nozzle_Connector.stl and Pivot.stl Enjoy! Note, some people experience collisions with the frame, I don't know how to solve this as on my LM2, the X switch can engage and I still have 3-4 mm clearance with the frame, and about 1mm with the profile wheel nut. Even it i move it all the way up or down, my only collision is with the X coupler, which ges in the way when the laser is too high.
