I am not new to 3D printing but have always used a direct drive extruder. I have started researching bowden setups and am seeing discussions about the quick disconnect fittings. The issue with the fittings commonly used is the small amount of play the tube has, even when the clips are used. What do you guys think about using a compression fitting? Or is this not even a big issue if your bowden setup is tuned properly?
Luv Those Guys!
If they had something like that for 4mm tubing, I might be willing to try it. Play isn’t a big issue though, you just increase retraction to account for it.
I’ve tried a couple cheap 4mm tube compression fittings from Amazon. They don’t have any play, which is nice, but I managed to blow one out. I think you need to tighten them a very specific amount to get proper grip, and then drill out the ID where the swage sits to get the clearance back. PTFE is really a lot softer and more prone to creeping than compression fittings are usually designed for.
I wonder if you could get a collet and thread the inside for grip then use it.
