Under extrusion at splices
I do a lot of prints without the purge block. i.e., colour change at height and random mode. I’m getting under extrusion at the colour change. Everything else works absolutely great so I’m wondering if it could be a splice tuning issue? I also had a note pop up saying my splice tube is old and should be changed but I wasn’t experiencing any problems at the time so ignored it. Could this also be a contribution? Obviously when I’m using a purge block under extrusion and the splice isn’t a problem, but a hole in the print at the colour change is!

Is this a good question?

Interesting issue Matt,
A peppering of questions-
Do you see any necking at the splices?
If you break a splice by hand is there an air bubble in the middle?
If you extrude a splice manually, what is the behavior of the plastic coming out of the nozzle? does it break, bubble, pause, etc.
I’d expect splices to generally cause over-extrusion where the splice bulges slightly! Always interesting to get the opposite of expectations lol

I like to be different! As below today I've changed over the splice tube..if anything continues I'll be back for help. But fingers crossed it was just that as the old one was a bit out of shape.
