Re: FLSUN SR: direct-drive and water-cooling
Thanks for these advices! I'm using a direct drive extruder, but my goal is to print high temperature materials, like ABS or Nylon, so I think I need a good cooling. For PLA, the effector alone may be...

Another question: in the separate cooling part version (which also better handles the extruder with 4 screws instead of 2), is it better to have the PTFE tube go through it, down to the heatbreak:...

It is a difficult question to give a definitive answer to as too many variables come into where the best place for any PTFE is. The most commonly used solution is to have the PTFE end well before the...

What "double ball joints"? The IGUS joins are either a simple rod end or a ball and cup with a simple " bearing" plastic part in the middle making it slip better.
