Hey! I noticed there is a lack of a thread for a boom arm for the LR4 or specifically. As I’m having mainly issues only with my 70mm dust hose being very heavy and uncooperative, getting in the way of the gantry and core and after cutting for hours it always tangles up the moment I look away and m…

[image] For now, I’ve somewhat come to a visual coherence between the table and arm. I’ve also got the length for it to reach corner to corner. [image]

So, since I have 3 meters left from the 32mm pipe from the gantry and rail of the LR4. I think of mounting it upright in the middle on the side of the table base, the mounting will be the easy part, plenty of ideas come to mind.

Btw, this was the start of the idea, please tell me I’m not the only one who needs to do a quick ugly drawing so I can explain to myself what I want to do :face_holding_back_tears: I have whole notebooks full of things that I have made and also maybe 99% of them which have never seen the light of d…

That’s a pretty cool design! Did you use just washers and thread without any bearing for the swiveling? I’m making it attached to the table base as I want it to move around with the dust collector in the table base and not wall mounted though, so a double arm with big lenght i won’t use fully in the…

Being brand new to CAD and CAM and CNC as a whole, the 3d modeling will take me some time, someone skilled in this will probably model and cut it within a day… Now im searching for tutorials how to make the bearing seat/channel spherical and how to set it for the ball nose bit. [image]
