so I managed to shear the SS heat break,leaving a piece I can't remove from the block, & now I fear I'll need to replace it, the block,and the heat sink, as the piece in it also won't back out. Is there any tips on removing the heat break when it snaps off like this? I've tried pliers & turning counter-clockwise, but it's just crushing/stripping the SS break... It's been a a frustrating chain of events- this was third time the V5 was leaking PLA, where you have to dismantle & try to remove the seepage that leaked from from top of block into the thermistor & heat cartridge, thought I wasn't tightening it enough so tried to tighten while hot, & well, narf! -it sheared right off.
