Did you check to make sure the path through the extruder, the aluminum mount plate and hot end are aligned? Push a prince of filament though from the top and feel for a clear path or snags. Also, is your hot end oozing? Its a known issue with Budhashnozzle and pretty easy to fix. I’m sure your issue is correlated with the disassembly / reassembly of the hotend and those two items are prime suspects.

Ok guys,
So it looks like the source of the problem was indeed the filament…which makes a lot of sense. here’s the reply I got from filaments.ca
Hi Jonathan,
Thank you for your email. I am sorry you are having issues with the ABS.
The creative series filaments were unfortunately prone to some quality
issues and we have since stopped producing it. If possible, please send
us a picture of the issue you are experiencing as well a picture of the
spool itself with the label on it for our records.
In the meantime, I am shipping you a free replacement from what we have
left in stock of this filament.
*edit, they are selling what’s left of the creative series stock and then discontinuing it. They’re sending me a replacement roll of the standard ABS stuff…
I’ve been using ORDSolutions ABS filament the first roll made pretty rough prints but I chalked it up to being a n00b. The beginning of the second roll I was able to make prints like this
Dang pretty looking, dimensionally sound, with only a couple of minor uglies on bridges and steep overhangs.
And now I’m having trouble even doing this–can’t even get through the 45° section, which is leading me to start putzing with slicer settings and machine calibrations
But the bottom of the spool looks like this. So maybe I should just pull the roll of and load in some better filament as a first test.
So in short I would say Yeah filament quality is a big factor in how prints turn out. But here is a case for having a “well oiled and tuned” machine.
These prints were done in series with the same filament (ORDSolutions ABS white) from the same spool with the same .gcode. All the above prints were done with the modifications and from the same spool.
Haha, that roll of filament looks nasty!
you can still print with bad filament, just makes it a lot harder to dial things in, and its hard on the extruder parts because the oversized oval parts stress the tensioner.
I can’t wait to swap my bearings and rods, I ended up sourcing rods from a local general bearing For like half the cost! Not sure why I didn’t think of that in the first place…
Is there any other reason to change brands of filament other than price? I have only had the printer for a month and have only used the Lulzbot filaments, HIPS to be exact. I was looking online at the filament on Amazon just to see what was getting good reviews and might be a bit cheaper. I wanted to try out some abs and found the IC3D brand on Amazon had good reviews. It’s about 7 or 8 bucks cheaper than the Lulzbot brand too. But now looking at the roll that Brew4you posted, I’m wondering is it really worth it just to save a couple of bucks. The Lulzbot stuff comes from Pennsylvania and gets to my house in about two days. There is an Amazon distribution center here in Baltimore, so I can usually get stuff from them same day or next day. I may just have to try one roll and see how it works out.
It’s a tough call and I would say a wash. I paid $20 buck for that roll but only half of it is really useable so it would be like buying a $40 roll. Add in frustration and putting around and factoring in extra waste I would equate it the equivalent as costing me $50 for that roll.
Then again I can’t always afford to spend $100+ a month on filament, especially if I’m just messing around and not selling any of the prints. I think–like anything in life–it’s a balance. I eat the cost of trying different filaments because I’m still new to the industry and I’m generally a curious person.
