My New Matter MOD-t hot end failed. Perhaps yours did too... Head over to the wiki to learn about how I got my printer working again.

Background

Having no experience with 3D printing, I inherited a MOD-t and started my journey. After getting it all set up I managed a handful of prints with moderate success before having the clog of all clogs.

At the bottom of the image above you will see melted filament within what I assume is a now-deformed, proprietary PTFE liner in the proprietary throat of New Matter's proprietary hot end. Despite a thorough search, I could not find PTFE with the interior and exterior diameter that worked with New Matter's throat. New Matter wasn't much help, seeing as it didn't exist anymore, so I was up the creek without a... hot end.

Be that as it may, I was mid-covid lockdown and the printer had become a much needed source of interest and entertainment for me and my kids. As such, I set out to build a replacement hot end to get the printer up and running once again.

Over on the wiki you will find a description of how I got my MOD-t up and running again.

It should be noted that, having gotten the printer operational with the new hot end, I continued to have issues unloading filament, just as I did when using New Matter's hot end. I subsequently learned that in response to others reporting the same issue, New Matter ultimately advised users to stop unloading filament entirely. As such, I have taken to leaving my filament loaded, and when I need to change filament I simply cut the existing filament and use the "Load Filament" function to feed the new roll in, letting it extrude until I see the new color.

While this process worked for me, I make no claims as to it's effectiveness, safety or otherwise. Should you choose to follow any of the guidance provided here, you do so at your own risk... you and only you are responsible for the safe and proper operation of your printer!
