I would make sure your fan is moving sufficient air. Maybe the bushing is wearing down and it’s running slower.
Looks like your heat break unscrews from the heatsink, maybe some fresh thermal paste to help the transfer. Some types can turn into insulators if over heated too much.
The clogging I had was a result of creep because I was turning off the machine before the cooling fans could finish bringing the temps down. After the fans were off the heat would move up and swell the filament. After I started leaving it on longer and not using emergency stop for print failures my clogging went away.
I don’t have hands on experience with this, but I can say that once you move into addon cards the chance for hotswap from drive bays goes up. Hotplug is a feature that many of the on board and lesser data chips don’t support well.
Also remember there is a problem with mixing material type in a single nozzle. The purge is not full and will change the chemistry/behavior of the plastic.
The new multi nozzle Bambu suggests using the alternate single filament nozzle for a different material type.
I think it was a video about the h2d from 3d printing nerd talking about this.
I’ll start with I’ve never actually tried using tpu despite having a roll. I also have a second non mmu printer.
What I do know is there there are multiple levels of softness with tpu. I think I was watching a video about the Prusa Core One, talking about how it handled tpu, and they needed to step up from super soft 60 to less cooked spaghetti like 90 just to feed up the tube and to the print head.
I also remember the MMU settings in the firmware have a material type option per input. I don’t recall if TPU is on the list, but most others are fine without changing this setting, so maybe?
are you calling me old?
pfsense had tracking of the gateway built in, check your router to see if it already has something.
I don’t remember why but years ago I opted for Moode over Volumino. Just upgraded from a pi2 running Moode 8 to a pi3 on Moode 10. At some point they upgraded to a 64bit base os forcing my hardware update.
Local library from a Nas, Streaming sources , mpd controls , connects with many platforms, started using it with Home Assistant music server last summer running my outdoor speakers.
