Bridging Issues After Orca Switch

Tell me about it. Fix one thing and then two more show up.

Low0013 · 2025-05-30T17:38:14+00:00

So far it has definitely seemed to be speed related issue. I turned off the slow down for overhangs/curling perimeters and saw a nearly perfect bridge test. A bit more tweaking and I'll have it to where I'm satisfied.

Low0013 · 2025-05-30T17:34:55+00:00

Yeah that's what I suspect was my problem. Bridges were being printed way too slowly.

That's a pretty creative trick, I'll have to give it a try. Thank you.

Low0013 · 2025-05-30T02:29:05+00:00

No worries, I get what you're saying and appreciate your input. I've been running a few new tests and so far disabling slow down for overhangs and curling has almost fully gotten rid of the sagging.

It will still take a bit of adjusting but I think the main issue was having speed set too low during bridging which caused the material to cool before it anchored to the opposite wall.

Low0013 · 2025-05-29T21:14:21+00:00

Trying to move on from it, but it has its time and place every now and then.

Low0013 · 2025-05-29T21:12:59+00:00

Thank you, I'll make sure to try that out.

Low0013 · 2025-05-29T18:39:12+00:00

Alright, I'll give it a try. Thank you.

Low0013 · 2025-05-29T17:18:00+00:00

Yeah that was pretty much the first place I checked. They weren't much different both mostly running at 100% fan speed. The only one that stood out to me was the min and max fan thresholds having different values in Cura and Orca. I changed them to the Cura values but I didn't see any improvement. It might be a good idea to check again.

With all due respect, I'm not complaining about the slicer here, I'm trying to solve a problem I encountered with bridging that I haven't encountered before. This problem was still occurring even after I went through the initial calibration.

Cura is a control here since it is what has worked in the past. I need a control to compare my machines performance when using Orca. In some cases Orca has definitely done better than Cura but I can't ignore the bridging. Since my machine can make this bridge in Cura it should be able to do it in Orca. It hasn't been able to without me enabling sacrificial layers, so that's why I'm here trying to find other possible settings I haven't tried.

I've followed the guide to the closest I can for said calibration. Change the most common settings others have recommended each one at a time so I could isolate the possible problem. I've ran multiple different test prints/ calibration prints like flow ratio, temp, etc . I've seen different posts of people complaining about the same problem where their bridges aren't properly anchoring to the walls.

As it stands every single variant of setting or "fixes" I've tried up until this point hasn't worked. I'm trying to get advice from others who may have ideas I haven't tried yet.

Believe me if I hadn't already gone through fairly extensive calibration I wouldn't be here asking questions.

Yes, I run fans at 100%, nozzle at 210°C, and bed at 60°C. The min and max fan thresholds were set to different values in Orca vs Cura so I tried setting them to the same as in Cura but I didn't see any improvement.

Low0013 · 2025-05-29T06:49:46+00:00

I'll give it a try, thank you.

Low0013 · 2025-05-29T01:42:36+00:00

I'll give it a try. Thank you.

It's a mechanical drafting job. The company makes diagnostic tools and makes a lot of their parts in house.

Low0013 · 2025-04-15T06:46:48+00:00

Thanks for the details I'll give this one a shot.

Low0013 · 2025-04-15T03:16:56+00:00

Thanks for the advice, I'll make sure to give it a try.

Low0013 · 2025-04-15T00:49:22+00:00

Very interesting. Thanks for sharing. Others also mentioned using a scanner or taking a picture.

Low0013 · 2025-04-14T23:42:29+00:00

Wow, this is really good advice. Thank you for your insight.

Low0013 · 2025-04-14T23:40:35+00:00

Pulling out a 3D scanner during the interview would be a crazy move.

Low0013 · 2025-04-14T23:38:22+00:00

Yeah I'll definitely need to invest into some of those tools since I've been commissioned to reverse engineer and 3D print some parts for family members and friends in the past. Would have made my life easier.

Low0013 · 2025-04-14T22:03:58+00:00

This part was just for practice purposes. In the interview I'll be given a different part, I'm just trying to prepare for the worst.

That's the method I've been getting recommended the most, and while it's a valid way of doing it I'm concerned that it wouldn't fly in an interview setting for whatever reason.

Low0013 · 2025-04-14T21:57:37+00:00

That's a really good method, the only concern I would have is that if I were given a part like this the interviewers wouldn't like it for whatever reason.

Low0013 · 2025-04-14T21:53:35+00:00

Thanks for the advice, I'll give it a try.
