PETG fail

I have printed PETG on my E5P. I printed a few temperature towers. They're not pretty, but they're getting there. Since I'm currently dealing with a Y axis issue, I've switched back to PLA for now.
Which, BTW, leads me to a question for you. Have you had any issues with your Y axis suddenly and randomly quitting in the middle of a print? It's an issue a number of Ender 5 Pro users are experiencing. Have a look here: https://community.octoprint.org/t/y-axis-randomly-stops-mid-print-ender-5-silent/
Here's a photo of 2 attempts to print a lithophone, the left 1 vertically, and the right one horizontally. In both cases the Y axis stopped moving, leading to filament buildup in 1 plane.
Here's another photo that shows it pretty clearly:

I have no problem with the Y axis.
But I found the problem. The extruder could not pull the filament. Video: https://photos.app.goo.gl/A3kLkkkSu4XdUHBa6
After that ai print fine with PETG.
The problem is, I don't know how I solved it. I disassembled the extruder and put it back. I didn't do anything to him. Then it went. However, I reduced the print speed and reduced the ventilation.

Man, those are some ugly cats 😂
Anyway, taking the extruder apart & reassembling it could well have freed up some 'sticking point' in the unit. My extruder started making occasional squeaking noises, almost like a bird's mating call. I removed the idler wheel, put some sewing machine oil on the bearing and the noise has stopped.

I found the problem. The Capricorn tube is not properly mounted in the extruder. It has a space and it is clogged. I disassembled it and reassembled it in the right place. It was very difficult to remove the Capricorn tube that was stuck in the hotend. I'm going to test.1 Photo

I have done my first prints on an Ender 5 (not Pro) in the past couple of days. I have an old roll of amazon basic and the temp recommendation is 230-240 and according to the 3dp reference above, bed temp was set to 70. As I was in a hurry, didn't do a temp tower and just did a cube. It worked great. Then came the real part and as it was larger, couldn't get good adhesion on the factory magnetic bed. So upped the bed temp to 85 and the hot end to 235 after a couple more trials. Been working ever since.Country Bubba
