I have tried PETG twice (different spools) with the same odd results - the first couple of prints come out perfectly. Then all other prints refuse to stick to the bed. I have been really confused by this as it is happening with the exact same gcode as the good prints.
I first tried with blue PETG, then white PETG. When I switch back to PLA Pro everything works fine.
This is what I was printing http://www.thingiverse.com/thing:795954 I printed one set just fine in PETG, and then tried to print a backup and never could get it to stick.

You might need to pop it in the oven at 70F to dry it out. It might have just absorbed some moisture.

If it is a moisture problem rather than putting it in the oven, you might try heating your 3d printer heat bed to 50 to 70C & placing the roll on the heatbed for a half hour on each side to pull the moisture out. I am not sure what temperature works the best.

This time elapsed between the first two prints that succeed and the following prints that fail is less than one hour - moisture is not the problem.

This used to cause me issues but mainly with layers not bed adhesion. Worth a try checking into.

Direct drive Prusa i3V with Hexagon hotend
Greetings all,
Here is a little something I fabricobbled over the last couple weeks. I converted my older i3V from the Greg's wade extruder to a direct drive; mostly because I have gone through several of the big spur gears over the last year due to them getting a bit too hot inside the enclosure I am forced to use to keep ABS prints from warping.
It took a bit of tweaking but it works, and much to my chagrin, it works pretty well. I was able to get it working the Hexagon hot end that originally came with the printer. It seems to push 3mm filament ok so far, (I have a lot of 3mm filament that I don't want to waste but will be switching to 1.75 as soon as I run through it all) All in all I'm pretty happy with it and thought I would share.

It sounds like moisture to me as well. I may have missed it but have you tired putting some cardboard or something around to create a simple enclosure? That used to help me print and stick a lot.
Going a little off topic, I'm kind of in the same situation as @DrMacZed but a little ahead of him. The extruder mount I used for my Maker Farm was the Itty Bitty and a few years ago it split. I unfortunately had not printed a spare so my machine was kind of out of order. I recently gave it to a student along with about 25-rolls of filament. I didn't want to trash it all but not sure it was even usable. I told him to dry it out well and it might work. I've purchased a Bambu P1S that's 1.75mm so I had no use for the filament. Once he gets the printer working I'll be curious if he has any adhesion issues from moisture still in the old filament.Bambu P1S/AMS
