Re: Edges in prints are curved

I understand about the problems with running the fan with ABS, I've had those myself. But running the fan at 50% or 60% (which feels to be WAY less airflow than 1/2 of 100%) seems to avoid those problems, while helping the curving. At least for me, anyhow. I'm printing on a Lulzbot TAZ5. The cooling...

Re: 3.0.2 Crashes selecting material profile

Woohoo! That seems to have fixed it! I'd exported all my profiles to a safe spot on my hard drive before doing that, which turned out to be a good idea, as doing that deleted ALL of my profiles. But importing them back in seems to be working fine, and now I can make changes and save them, etc. norma...

Re: 3.0.2 Crashes selecting material profile

UPDATE: that's not the whole solution, I'm finding out. When I "Save As New" a known-good profile under a new name, and then try to modify that and do an "Update Profile", the program crashes. Also, if I Export a known-good profile (and see that it's a good-looking 22K file), change its name in Wind...

Re: Edges in prints are curved

While folks say you don't normally run the cooling fan when printing ABS, I find I have to do that, at about 50% or 60% fan speed, to keep that effect from happening.

Also, I usually heat the bed to between 100 and 110, for ABS.

Re: 3.0.2 Crashes selecting material profile

I've been seeing similar problems lately. Here's what I (think) I know now. BTW, I'm running S3D on a Windows 7 Pro, 64-bit PC. If I look at all of my exported (saved to local disk) .fff files, I find that if they aren't zero-length, they have one of three lengths: -- 8K - 9K (these turn out to have...

Re: Help for printing overhangs!

Adding supports will help a lot. That way the material can't sag, so it's not pushed out of the way and letting more plastic build up. You can experiment with support density, but it looks like you'll need supports all the way around, without gaps. Cooling should help, just for grins you might try r...

Re: Clear "Resent open files"

You might try deleting or renaming the file S3D is trying to open, it may be able to handle a "file not found" situation OK.

Re: Rafts affect on Temp and Cooling Settings?

I don't know, but this might be a quick way to test the effect of the raft on layer-based temperature setting issues;

In the per-layer fan controls, set the cooling fan to come on at, say, layer 5, then go off at layer 7. Then watch to see when it actually starts and stops running.

Re: How to Use a New FFF at a Specified Layer

And you can save lots of testing time by dragging down the rifle round underneath the print bed so only some of the exposed bullet area is above the surface, then S3D will just print that part of your file. It's a BIG time-saver in situations like this!

Re: What is best way to improve the surface of cylinder?

...And once you've got everything gathered into a seam, you can then use coast/wipe and such to minimize it. To gather it all, go to the Layer tab, and play with "Choose start point closest to specific location". I normally use a "location" that's at the middle of the X-axis travel and waaaay back a...
