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.

Thursdays. I never did get the hang of Thursdays.

I wish I could upvote this twice.

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.

I have heard that when cars were a rare thing in the Old West that drivers had to stop at intersections, get out, and fire a gun to warn any horse-powered cross traffic. It sounds like total bs but there have been stranger laws…
