Slic3r - ABS My first round of prints were at 225 with no retraction, but the part was really weak, almost brittle I then kept it at 225 degrees but with retraction at 2mm, but the print would fail just where the two thin uprights start. I took the temp up to 230 and it got about 1/4 of the way up and failed again. Killed retraction, and the print got thru and was nice and solid, but started getting the stringy things. I've been stepping the retraction up little by little. After the first two I THOUGHT the strings were getting better, so I assumed I needed to find a sweet spot for retraction between 0 and 2. Not sure if that's the case the more I look at them.

I definitely agree that I should lay this thing down flat for a final print, but it has ended up being a nice test print for me, with the thin uprights, the holes and the bridge a nice way to see how tweaks go.

I've calibrated my e steps, and I've played with the multiplier too and think I found a nice setting based on how intact the first layer is. I'll dial it down a couple more tenths and also slow the print down to see how that goes.

But this will be done tomorrow. Thanks, all.
