3D printing

Every time I switch my printer off, when I restart it prints about a meter of filament and then the filament ends, The end of spool detector does not activate and there is plenty left on the spool.

Reloading the filament always works

Thoughts?

^^^ typo for when?

Make/Model?

Don't be silly., It's just one of over a hundred random statements I have in my signature file.

This one dates back to around 2016

Since it is the only one you have ever commented on, I guess it's *you* that thinks about it a lot.

I nearly bought one of those.

Does the state of the runout sensor show up within fluidd?

Its fairly good value. And versatile

what is fluidd?

I got cold feet when some early ones needed replacement extruders

Part of the klipper GUI

Oh. I think I rooted mine and mainsail-ed it? Wasnt a great deal of use except I can print direct from the slicer.

But it appears I can ssh in and look at the logs.

That is definitely a place to start, but I think that actually the issue is that the filament breaks downstream of the sensor. So the filament is still in the sensor, but not beyond it, and the extruder just starts the print with the broken bit and than peters out.

Damp/old filament? I had old reels of filament become brittle. Baking the filament on the heated bed at 70C for 8 hours dried it out and it and then printing with it had surprisingly good results.

very likely

That might be a perfect use for the AGA's 'warming' oven.

But 70°C is beyond PLA melting point really

I assume that's not exposed to the combustion gases, otherwise the water produced by combustion might rehydrate it.

I got a cheap filament drier from Amazon - you can chuck a couple of spools in it and then tell it to keep it warm with air circulation for a few hours to dry them out. You can also feed directly from it if you want. It makes printing with things like TPU cleaner and less stringy.
