I am not sure about Hatchbox TPU; there is information about other flexibles in other threads. I find a larger nozzle helps, 0.50mm, and I print roughly 50% the speed of ABS,PLA, etc. Your temperature also seems low. Other flexibles I use require 250C or so. I had trouble printing softer filaments w...

I have used several flexible filaments. You can read about them on "Insta's Filaments That Work on the M2" thread.

If you intend to print the two different filaments on top of each other, the nozzles have to be the same height. If you are just using one, it is OK to have the one not printing higher.

From the extruder temperature, I presume you are using PLA. Are you using the cooling fan? At which layer? One thing you can check is the Z-height. What are your Layer1 and Layer2 Z-heights, as you print? I usually see 0.18 on Layer1 and 0.38 on Layer2, which is what I want ,(0.20 difference), for a...

Temperatures, extruder and bed? Materials, filament and bed?

Go to the FILAMENT thread. Too much there to discuss here...

I like the base, too. How do they sound?

what can I do to have a stable large format print???? I have had some materials let loose of the bed, but only on tall, skinny parts. Your broad, flat part should not be an issue. Two possibilities I can think of: Your bed is not clean; Your nozzle is clogged. I have rarely had a problem with PETG ...

What is your bed? Kapton tape on glass? Is it possibly not clean enough? Off hand, it appears your initial gap between bed and nozzle is too large. The threads of filament appear more round than they should be if they were being squished enough. You might try adjusting your Z-axis knob to reduce/fin...

I will be there and look forward to meeting you, Rick.
