I have blown apart a few PC4-M6 fittings in the last couple of days, after breaking my last good one a few days ago. On the ones I keep breaking, the metal part the grips the PTFE tube seems pretty thin. There are so many out there, how do I find good ones? Also, what should I set my max extruder settings to to avoid destroying my fittings? Or, do I just have the tension on my extruder gear too tight? Should I just let it skip if it can't push fast enough?
It's been a while since I worked on this thing, and I put it away because I was frustrated with print consistency. I think all my problems getting it to print consistently have been extruder related, so I'm just trying to work on that.
