Having soldered many of both, I should have noticed. I literally just threw out a big pile of both that have been loitering in storage for years. I’m still surprised when old tech (for any random definition of “old”) pops up.

Serial cables. How quaint.

I wish I could upvote this twice.

Thursdays. I never did get the hang of Thursdays.

Update: I wasn’t able to fiddle with it for a few days but after getting back to it have something I like.

My current settings are based on the feedback in this thread and:

z-offset made the single biggest difference. I reset the printer config and re-leveled.

I printed a tower a few days ago and it looks good anywhere from 200 to 215. I’m going to keep trying though.

z offset / nozzle height seems to be the thing. I’ve raised it up and it looks better. After that I played with the temp a bit and it seems to be happier around 210-215 though there is more stringing.

So far, all attempts at ironing have been a disaster, both zig zag and concentric. I’m going to continue dialing in the z offset and temp before ironing.

Weird. I couldn’t post the original pic but a screenshot of it seems to work.

The spool doesn’t say “silk” but the sticker does say print temp 215-230: https://www.amazon.com/Inland-1-75mm-White-Printer-Filament/dp/B084RDMG7C/ I’ll give that a shot & see if it looks any better.
