TPU and the runout sensor?

So I did the setup and printed the included benchy and lighthouse files with the PLA the printer comes with…so far I’m loving this printer!

Immediately switch to TPU filament since I actually have something I need to print in this and the runout sensor cannot see my filament. I had to put a small piece of PLA in the thing so that it would let me print. I guess if anyone else gets a chance to try theirs out, let me know if your runout sensor works with flexible filament!

I did a few TPU prints today, no issues. I have nija flex green. Is yours transparent ? I did have to make a lot of adjustments in my TFU profile to make it work though but no issues starting to print.

The stranger thing is, this sense stop the print at any time if it sense a runout. You need to kick start it with pla and then it printed fine with tpu?

I’m using Overture Black TPU. I gave up for the moment and went back to PLA stuff.

I printed both really soft/flexible TPE and fully transparent PETG both thru the runout sensor. No issues. It might be more related to connection on your device?

I doubt it since I’ve had zero problems with any other filament. It sounds like it may just be related to my specific brand of TPU.
