I remember you mentioning a MK2 sometime ago on a different Talk post; is that what you’re using the Nylon with? If so, you’re in good company, and that advice is from my experience with mine!
That definetly looks like a starting error. It could be a couple of things.
I think it is not purging your hot end enough before the print, so small amount of plastic gets on there, that gets pulled on the next layer. I am leaning this way, because of the direction of the pull.
I can also see you are either too close to your bed, or overextruding your first layer. This can also leave a blob when the outline meets itself when it completes the outline, again creating a situation where there is a little too much plastic, that gets picked up by the extruder on the next layer.
Definitely add or increase skirt, or raise bed a little, or print less % of first layer. This should make it go away.
I bought some Taulman filament from Amazon. It popped and sizzled when it was printing. It had water in the filament. I took the roll to work and put it in the welding rod oven for 3 days. The welding oven maintains a temp of around 95 C. The filament prints much cleaner and better. No popping and no sizzling. The color did fade and the spool warped but the filament was OK.
I really appreciate the advice. I need to go back to the cube and work with it. Other prints are printing nice however so hopefully it is just some adjustments/fine tuning but overall a good start with the MS hotends so I am happy so far! Hasn’t been a disaster!
Yeah, it popped and sizzled right out of the bag. I read reviews on Amazon with the same issue, but decided to take a chance. My buddy ordered a roll a few weeks later with the same issue. And yup its taulman. The original clear color faded to yellow.
