Spool unwinding

Awesome! So it's not just me, then?

it still trys jumping side of spool at times so I take wire coat hangers and bend them to fit close to sides across spool and hook into opening of spool so they hang at bottom and filament cant unwind off spool more than half way around. have different sizes for each size spool used

Take a look at getting the spool above and centered rear of the printer.  A big lazy arc on the filament is best.  Take a look through my posts for a picture of how my holder and enclosure is set up.  The filament enters through a hole centered on the printer.  I am not suggesting you do as I did but you could duplicate where and how the filament is guided.  I can run full spools and I have never had it jump the roll since.  I also have a friend that just used PVC pipe to hold the spool directly over the center of the printer.  It's an ugly setup but it works and doesn't bother him

The guides are a cool solution. I use a filament dehydrator. It is just a box with a lid made of polycarbonate that holds my reel the way I want so it does not uncoil and stays dry.( small bags of dessicant inside)  A small hole in the lid and some half hoops on each side to hole the reel off the bottom. Simple and fixes two problems for me.

Try a loop of PTFE like on the filawinder.

Having a nice easy filament path is important.  I have never been a big fan of running the filament through that hole in the back.  It places a lot of unnecessary force on the extruder as it pulls the filament which can cause the filament to strip or even skipping of the y-axis.  If you have play (and we all do) in the carriage it will also lift it up and down throwing any calibration you do right out the window.  I know a lot of users run it this way but wanted to point out that a nice lazy arc with minimal resistance has been well established for several years as the best way to feed your printer filament.
Here is a picture of how I have mine set up.  Even with the fullest rolls It never jumps the spool even when I have three on there and pull from the outside spool.

Hope this helps

yeah I got the cover with mine and SD didnt think about that tight bend for filament seems. but I do like having the foam dust wiper and like keeping everything including filament covered to keep clean and dry plus controling operating temps better. I have seen some nice plexy DIY covers that would be a better investment than the metal 'deluxe' cover plus load filament above extruder like some delta printers did. saves floor space too
