It sounds like your thermistor may be going out / bad.
Using a multimeter, set it to 100K Ohms and probe the thermistor at room temp.
The thermistor should read ~100K +/-20 ish.
If it is extremely high or low, you may need to replace the thermistor itself.

Hey, @D-MARTIN !
It does not look like the file you tried to send made it through, can you please try to attach it again?
I agree with @mpirringer It very well could be wet filament.
If you are still seeing the banding after drying the material, you may consider slowing your print speeds down by 5-10 mm/s.
I have also included an article below on how best to dry your filament:
My best guess here is the printer profile that you have selected does not support that specific feature. That said, you may consider setting it up as a new machine as a whole so you can enable that during the setup.
I have consulted a couple of people here and the answers are pretty consistent. The instinct is to recommend a nylon or polypropylene for the appropriate strength and flexibility. However, the size of this model as you described is the chief concern. It is extremely difficult to truly make a recommendation without seeing the model itself. Not everything can be successfully 3D printed and not everything that can be printed for use in an actual application. If you can provide the model or a picture of it, we may be able to give you some more concrete answers and recommendations.
Hmm, this one is a bit of a tough one.
You mention that you upgraded the hotend, was this sent in for an upgrade or did you do it yourself?
Please reach out to us at Support@matterhackers.com for this one, this may be a bit lengthy.
It could be a number of things really but you may have the tensioner a bit too tight on the feeder to start. Does this happen with every spool or just the one?
However, we would be happy to help troubleshoot the material with you if you would like to reach out to us at Support@Matterhackers.com
It is not a machine that we have used or tested in house and have not made a profile for it accordingly. MatterControl is open source and you certainly are able to manually create a profile. As long as the machine uses G Code, MatterControll will be able to operate the machine.
To do this, you can navigate to Hardware> Add Printer> Other. From here, you can ender the printer's specifications and dial it in accordingly.
It looks like your PET may be very wet.
Wet material can cause all sorts of issues that look just like this so I would recommend drying the material as PET is very hygroscopic.
I have also included a link below that you may want to take a look at about how to beat moisture in your spools:
