Filament Joining

I have...I know there is one unit that actively splits and rejoins different colors.  I'm pretty sure there is one that just fuses the ends of whatever you want.

Do you know if it works with resistance heating? I'm thinking of just getting two halves machines for 1.75mm filament and then use resistance to heat them.

A quick google search yields a lot of information.

I'm glad that this topic came up as I'll soon encounter the need.

Do not know, but here is the unit I was looking at before I found at how easy it was to just swap out spools during the print process (https://www.mosaicmfg.com/).

Thanks!

I have an MK3 which alerts me when running out of filament, it lets me change the spool and will restart where it left off, works great.

Also have a Prusa Mini and tried the same procedure which it did, was able to change spools while in a print job but when it restarted did not stick well and produced spaghetti, luckily was near the end of the print but not so lucky I lost the print and about 3 1/2 hours of printing.  I will try this again with some test parts.

I've changed firmware a few times on my printer to try to get it to hang tight when it runs out of filament but it just hasn't worked out. I use a few plugins to help me figure out if I have enough filament on a spool to finish a job and that helps me be pretty efficient in getting the most from a spool. It would be handy to just merge the end of one spool to another though.
