Cause of jamming overtime can be
1. Your temperature is dropping over time. Try to raise printing temperature and see if it gets better.
2. Hotend cooling fan not powerful enough can also cause this.

Since option 2 usually will jam it for good, but what you have seems repeatedly come and go, option one is more likely.

It will be easier to identify the problem if you have more detail information if you have mod your printer in anyway.

Ultimately, they will be extruded in 4m lengths, but for testing purposes, I have created an STL that will - or rather should - print a 149mm length vertically. However, I have now wasted half a spool of filament trying to get it to print: from about 60mm above the platen, the print starts to fall apart or have significant gaps in it. Can you advise why this is and what can be done to rectify the issue? Photo attached.
