All imported profiles look good to me. I think we can close this now.

Should we make a new ticket for the Bridge profile edits (coming soon) or use this same branch but keep it open for when those edits come?

aww shucks!

Updated Dual V3 Polylite PLA Profiles, these will be incorporated soon.

I have been taking this into consideration for all new profiles and for all edits coming my way, as far as making a mass change I am unsure, @karrad, any thoughts? I don't anticipate major issues if we approve this change for all profiles but as for a quick fix it might be an issue, each profile will have a different layer height and thus a different layer to activate the fan.

We determined that the main culprit of drastic temp drops was low layer fan activation, this causes the air from the fan to hit the bed and reflect back up onto the heater block, after a few more layers there is a large enough gap between toolhead and bed that the air will flow outward. To fix you can increase your "Regular Fan Speed At Layer", this will give the printer a longer time for the fan to ramp up to the regular fan speed setting.

@karrad hmmm. Interesting, Does Cura Turn off Retration when using combing? this is new info to me, I can start incorporating this (provided it works) into the Quiver Profiles.

Ah, good to know. Ill keep this open for future triage :)

@karrad and @adam, is this an old ticket? I think we have already migrated it to supported. Just double checking before I close this.

okydoky, sounds good.

@karrad, have these been incorporated yet?

We are all supposed to be using FreeCAD for consistency. If @EricNugent makes changes in any way to a model it needs to be in FreeCAD. Most parts may not need built support changes at all, many will probably be fine using the generated support, which could save some time. If we keep built in support and keep doing that in R&D then Cluster can't change the part print orientation, layer height, or support preference. I feel like learning FreeCAD (yeah, i know... its FreeCAD, I'm sorry) would be worth it in the long run. I am not saying that we now make it mandatory for Eric build all the supports, I am saying we keep built supports open as an option on a case by case basis, we don't yet know how the generated supports will effect production quality and if it will increase or decrease production material waste. @david.hall thoughts? We will have to hear more from Eric when he is back but giving him parts that don't have set supports that force him to slice it certain ways that work around another persons idea might also save him time.
@logan , I mean that the supports do not retract when going from one area of support to another, only at the end, so if there are two areas of supported material it could string across the part. Yes, I have been testing all of my support settings for newly submitted profiles for a while now. If you would like to know which have been tested and which have not, it may take me a while to get you a list.

Sorry to ask for more clarification, @karrad All machines and profile levels for Chroma ABS and Village ABS, and IC3D ABS?

Ok, there are many pros and cons to both options here, some of which have already been stated. Concerns raised about using the Cura generated supports are that the supports do not have the ability to have retractions and this could prove to be cosmetically negative, also smaller support areas have a higher tenancy to pop off the bed causing print fails. Cura supports could also effect the geometry of the part very slightly, I don't mean that it actually changes the model but when it prints and cools it may shrink at a different rate or direction than we are used to for our geometric precision needs. The positives of using the Cura generated supports are the ability to ensure support coverage throughout the model as needed and this would be another way to ensure our Cura generated support process is working appropriately. Built in supports allow for consistent expected geometric results since its what we have been using thus far but it also limits the cluster production slicing ability which I think only cluster and data from production should be effecting. One of the advantages of 3D printing is our ability to rapidly discover and implement improvements to our product, having the support system built in by the original design team limits productions ability to perfect it through their production process. This being said, absolutely ANY support style changes should each be rigorously tested before implemented into production parts, accounting for geometric accuracy, strength accuracy, etc. I cannot stress this enough, DATA! My conclusion is that we use BOTH and we allow @EricNugent to determine an individual parts support needs upon arriving to him for initial slicing. Some models will benefit from a built in support that Eric could build and add using FREECAD (it has to be in FreeCAD), and other models will benefit from using a Cura LE generated supports.

@karrad, Can Do, I'll include running a couple prints after testing to my wiper pad and scrub pad testing process.

Mini 1 - Aero V1 - Profile Confirmations

Some other Edits were needed so I updated it since I was already running testing, Here are the edited Profiles.

I have been using these edits for the Flexy Dualy for a bit now and I havent had any issues starting my prints or getting material to start printing when expected. This all looks good on my end, Here was the combined edit I used:

Ok, one reel each for that should be good, Thank you!

It did cause wear on both nozzles types. I think we need to run these same tests on different levels of wiper pad abrasiveness to determine if we can use something like this at all. Ill post results here as soon as I have them for the pad samples I already have here.

Is this for profile development of just to test the filament run out?

Here are some relevant tickets open: T2885 , T2904 and T3759

Updates on wiper pad testing data can be found here: T2885 and T2904

Please see T2904 for #7447 Red Scrub Pad Data

PC-Max - High Strength - Mini 2 Aero V2

Thank you!

Sounds like a plan I will get on that, Thank you for the clarification.

Didn't see this before starting my 1st test, will get it in later

What manufacturer(s)? I will need that to make sure the appropriate profiles get edited

Do you mean Standard profile or High Detail profile or both the Standard and the High Detail profile. We don't support a Standard Detail Profile.

Sounds good here is our current updated list for testing 😃

It sounds like something I would want to test then. We will have to recommend they bake the part after soaking it tho since its nylon and it will get weak once it absorbs all the moisture it can. Testing all that will depend on time but I'll add it to the list!

Updated Profiles for Mini 2 Aero V2 are posted here: T4547

Not to my knowledge at this time. I am not sure if Quiver is going to have HS nozzles or Nickle plated copper. And even if we do HS, we may run into an issue with the smaller extrusion diameter (0.5 vs 0.8 and 1.2)

Any update on getting me a flexy dually @karrad?

Thank you sir!

@matth Are you printing open air or enclosed? Using glue stick or printing straight on PEI? Is the toolhead an Aero V1 or V2?

@matth also can you include which toolhead and which printre you are using and what firmware they have and what version of cura you are using :) Thank you!

We have fixed this through profile settings and the permanent fix will be coming here T3524
Closing this ticket out.

Status Update: Waiting for tested data to determine.

I am working on profile settings for Polydissolve now. Should have them settled today and confirmed for taz early next week.

@karrad thats the plan, ill post confirmation here.

My profile development on HS and HS+ taught me that, for PLA, doing the outer wall before inner wall makes a huge difference, especially when the extrusion gets thicker. I feel a similar result is happening here. @karrad, anyway we can get the HS+ PLA profiles pulled to our Moarstruder if they work?

UPDATE!

Testing report found here: /home/aleph/shared-j/devel/lulzbot/filament/taulman/Alloy_960_CF/

Unable to know packaging moisture effectiveness at this time, I believe the material had water contamination from before it was packaged.

SDS Checklist found here: /home/aleph/shared-j/devel/lulzbot/filament/taulman/Alloy_960_CF/

SDS checklist here: /home/aleph/shared-j/devel/lulzbot/filament/taulman/Alloy_920_GF/

Ready to go:

I am using 1.1.9.28 on a mini 2 with a Hardened Steel Plus toolhead, connected via USB to Cura directly. My LCD froze, I restarted the machine to get use of it back.

Gotcha, Ill have these fixes in soon :D thank you for letting me know

@logan @oliver @karrad
I have been testing various fixes and wanted to give ya'll an update.
I tried bringing the print temp down but I got repeated strip outs and extrusions just not adhering to the previous layers when I tried printing larger objects, I recommend printing at 260 minimum for Abs on HS and HS+. I know its hot for an amorphous plastic but since we are trying to extrude such a thick diameter of filament it needs to be hotter. Another fix for this is slowing the speeds way down but I have already slowed them quite a bit considering we are advertising speed for these toolheads.
I also tried killing the fan, and while I did have less warp, I did notice a decrease in overhang accuracy in addition to the expected bridging errors (pictures bellow).

@nathan was this for Verbatim PLA or one of the other ABS's? I haven't made any profiles for Verbatim ABS.

okydoky, I'll run a few different models to compare and determine the best middle-ground for our customers.

The SDS Failed: here is the needed info.

@Orias that makes sense, ABS bonds stronger at lower melting points, I am going to print some out to compare so I can get a better feel for the difference.

Hey @logan and @oliver, are you guys using Chromastrand ABS or IC3D ABS and which colors? I would like to run some tests today with these settings. Thank you!

I like those suggestions, I agree that we don't need to say its mandatory but I do see enough inconsistency on my end that I would feel better suggesting it in some way.

@karrad I would like to recommend that for all toolheads and printers, as good as we have gotten with ABS bed adhesion with the PEI and temperature manipulation, for customer use I think it would provide a more consistent hold if they use gluestick. I have to use it when testing ABS more often than I would like to without recommending it, so I would like to recommend it.
@adam PA-CF seems to be good out of the box from my initial testing, I will dry a new reel this weekend and do a comparison test today and Monday and let you know for sure then.

I would like ABS to have "Use Glue Stick on PEI if not enclosed" or something like that.

OH!! Xstrand should also have a "dry before use" warning or something like that. The drying recommendations are 13 hours at 158 F, then it should be stored in 30% Relative Humidity or lower when not in use. I am not sure how much of that you want to add into cura.

There should be new Xstrand updates pushed and ready for testing, this included a temp drop. I hope it works better for you. You may also want to wait until you can dry your material for xstrand, the results I have been getting from newly opened reels is not encouraging.

Xstrand should have a bed temp of 90-95 C, on PEI, with Gluestick.
PA-CF should have a bed temp of 70-75 C, on PEI, Without Gluestick.

Thank you @Galadriel! I am happy to see that. If you are looking for some extremes to test you could try something like baskets or crates that have a lot of open spaces along the wall, it forces a bunch of retractions and z hops, good for torture testing.
Happy Printing 😄
