Why does E3D V6 Gold HotEnd kit include PTFE tube with smaller ID?
I am assembling E3D V6 Gold HotEnd kit for Anycubic Mega-S. The V-6 kit includes a section of PTFE tubing (blue) with same OD as white tube that came with the Mega-S, but the ID is noticeably smaller. I am wondering if I should use it?
On my Mega-S printer, filament that has been fed into the bowden tube (and then retracted of course or I wouldn’t be able to see/notice it) has notches on it. You can easily feel the tiny jagged marks left by the bowden drive feed mechanism. Unused 1.75mm filament fits through the new smaller ID tubing fine. But if I try to push filament that has been through the feeder and retracted, it jambs. As I feed more of this filament into the smaller ID tube, it gets harder and harder to push. That can’t be good?
Any one have any suggestions? Should I stick with the original tube? Should I not be getting these notches on my filament?
Is this a good question?
