Don't cut the tubes. slide them off the end of the attached piece and reuse them. I get usually 8 welds out of 1 tube.

How long would you say it would take you to recoup the $50 in saved filament from this?

That is pretty much almost the same way that you fusion splice fiber optic cables.

I think it's awful! Even if I DO get it to weld properly, it ends up snapping when the printer is pulling it thru.

so the only thing about these welders that nobody mentions is that if the weld is slightly larger diameter, and its hard to tell it will jam in the Bowden tube or extruder and fail the print.

that's why I love that my printer will use every inch on the roll and just keep going just load a new roll

I was just downloading that spooler last night. Next project coming up. Now I’ll have to find the box and add that in line. I love my sunlu filament welder. The box for it is really cool

Or use a backup spool and when it runs out, the backup kicks in. I haven't had any leftover filament yet
