Have you looked at Polycarbonate (PC)? I have used the UM PC material with great success and, if I rmember correctly, it has the highest Tg temp of the standard materials. It also has it included in their presets now for both Cura software use and firmware for loading. That stuff is strong. Here is a quick link to the PC material for the UM type. Just know it is the only PC materials I have tried.

Did you use the file link to print a piece? Another work around would be to flip the AA and BB cores in the slots and then flip the Print material and support material in the back to spool in the proper direction.

I find it to be just fine the way it is. Not that your idea does not merit consideration, but here is my approach. I rarely do 2 color prints, so that may color my input. (Pun intended) But when I make a profile, it is either with or without supports. So, this does not really affect my way of working. But, I have also taken to saving "Project Templates" so that it loads everything with a small dummy model. I then clear the buildplate and load the model I wish to use. Too many times, I have relied on a profile, then forgetting that this profile had hollow objects and wind up with support material inside the model that will not come out. Using the dummy template project alleviates the need for a super long profile name to rummage through and I find a description of the type of project and material suffices for me. An example would be: UM3E_VaseTemplate_PLA-PVA-08mm_04layer.curaproject.3mf Since it is a vase (spiralize) print, I know that the PVA is just a brim. I am finding that almost all of my prints (PLA for the most part lately) seem to work fine with minor temp adjustments and that is not an issue as it limits the number of things I have to remember. Another example would be: UM3E_StatueTemplate-30gradin-3W_PLA-PLA-04mm_015layer.curaproject.3mf A template for: UM3E_StatueTemplate: Statue type of print 30gradin: 30% Infill gradual ( I will always choose the type on the fly at this time. 3W: 3Walls PLA-PLA: 2Color Print 04mm_015layer: 0.4mm Nozzle with layer height of 0.15mm But, that is just me. As I said, your idea does merit consideration and I shall do so. Always room for a different outlook.....

If you are referring to the spool insert to hold and feed the spooled filament, you can find a version to modify and print here.

The carbonized pieces you mentioned (Black Stuff in the print) is probably from the filament absorbing moisture. If you are using PVA for any reason, you may be picking some of that up as well. But as Gigi said, Latest firmware and software will make the printing more automatic since there are now presets that allow for these materials and their associated temps.

I am not sure what happened, but I would have printed it in the orientation of the actual printed object as you have it laying. In essence, flat parts down.

That is interesting. Once I whitelist a program (I am using AVG and it catches many, many things as well) it stays whitelisted. But, I agree about antivirus stuff being aggressive. I am never one to complain when the credit card companies, banks, or Antivirus wants me to verify anything. Too much going down these days. I do appreciate it.

Depending on the virus scanner and level purchased or free, I believe that it can be whitelisted on the local machines.

Well the spamers maybe too... From what I understand, the spammers are using bots to do this. They be powerful lil' thangs

"Feature"!! LOL!!! Yeah, but this reminds me of the old compuserve days. Back when the internet was civil..... We work together

I do not know if this applies to your situation, because I am using the regular print cores, but I have run, consistently with only a few exceptions, my printer (0.4 and 0.8 ) for prints for up to a week at a time without issue. Most issues have been environment related.

Yes, I tried the new Top Surface Skin Pattern, and it does pretty much what I was looking for, but why not just make it part of the Top/Bottom Pattern, by splitting that menu Item in to two distinct items i.e. Top Pattern and Bottom Pattern? That I could not say (Re: Splitting menuing). But I look forward to the stable version to come out. I, hopefully will be testing something out soon and do not want to overload my plate. I am already going nuts on spiralize and using fractals for lamp and vase shapes LOL

That be odd even on my strange-o-meter.

I can verify that I did find the same issue you did. I have not used any custom profiles lately. But, as soon as I stepped outside of the Ultimaker family of materials, the profiles would not show. Even if I made a new one and left it linked to the original material. Even if I duplicated a material from any of the sources, Ultimaker, Generic, etc, or created from scratch, it would not let me have printing profiles listed in the front panel interface. I have not used this for two versions, so I am sure you caught a bug. It was flawless before and I thank you for verifying the steps and pointing this out. I did the worst thing possible: I ASSUMED that it worked before I answered and did not test it. LOL It really did work before. Edit: Final thought, it would not show the materials unless I was in the nozzle it was created in while inside the material profile interface. I would load something that was created in the 0.4 nozzle and was in 0.8 nozzle and it would not show. As soon as I changed nozzle in the front panel, it would then show in the material profile editor.

Check to make sure that there is not a nozzle incompatibility going on. I will have to check this against one of my material profiles here soon as I finish this little project I am working on.

Good to know the brain is not totally dead. It may be why it did not get much mention. Having developed things before, in various industries, it can be bad to build up expectations in case it takes longer than expected or causes trickle down effects. Programming can be particularly nasty about unintended effects and can be a pain to track down. Better to say nothing than say anything at all in most cases. Oh!! And they have the Neotko Sanding feature being implemented (Ironing) and I will be happy to see how that helps. I am so busy experimenting with things that I just do not have the time to test these new features.

If I am correct, it does require a core in both slots. Do you have a core in both slots? Also, if you do have a core in the slots, maybe try to reseat the cores. I know that sometimes when I have done pulls and such, the core can be jostled a bit if I let the cores get too cold and have to pull like Paul Bunyan to get the filament loose. And check that the little connectors in the rear of the core are clean. I did have an issue or two a while back (Cannot remember specifics) until I pulled them out, cleaned and reseated them.

Ahhh, the old days when things were truly revolutionary and not just evolutionary. Remember when a 10MB hardisk cost (Literally) $10,000 USD? I am not sure I follow the last comment about things not listed for the new material. I have material profiles for all my specialty filaments (T-Glase, Ninjaflex, etc) and can choose those materials in the drop down menu just like the Preset materials that come with Cura. I also make sure I export my materials and print profiles as you can really clutter up that menu system. So, I load and remove as needed.

I do believe that this is addressed to one degree or another in the upcoming 2.7. I am having morning coffee, so I am trying to remember, but I seem to be remembering this thread when reading the new features. Or, I could have not understood what the new feature was. Ack!! COFFEE...CAFFEINE!! Must...mainline.....caffeine!! Set up the IV drip!!

Totally flipped from my experience. I wonder if it has something to do with cookies or whatnot. Since I primarily use Firefox and have to use Chrome to download and you are the opposite, it would seem to rule out an actual browser issue.

I've experienced the same problem for several months now with Firefox. Usually end up using Chrome to download the files instead of purging the whole History and cache out of Firefox. The links just act as though they are dead . . . Count me as a firefox user that has had link issues with the Cura updates.

I have used two types of PET filament. Matterhackers and T-Glase. I always put a surface of PVA on the buildplate. It helps in creating a barrier between print and glass. This allows for a quick soaking to cut the print loose. It also helps create a bit of tack for the filament. Is your glass properly cleaned? I get real anal about cleaning my glass with something until the fingers squeak on it and then the paper towels will squeak with it. Then when I put the glass down, I clean with 79% - 99% Isopropyl Alcohol (The purer the better) and preheat it to help my layer of PVA dry and speed up the pre-print prep phase of things. Other things to consider would include environment changes (humidity) and a good set of cold pulls and resetting your bowden tube as it may have slipped a bit up creating a gap for hot stuff to squish into. The humidity could create a bit of moisture and prevent your PETG from moving through easily. Also, are you cleaning the dust grindings out of the feeder? Just use a clean thingy like a gravy baster to blow out fine dust as that will contaminate the plastic and create a bit of drag in the tube. The bowden tube can pull a bit when unloading a filament if the inside is a bit sticky. The same as keeping it from flowing easily. Hot and cold pulls may be needed to get rid of clogs that can form when using incompatible materials. For instance a use of ABS and then PLA can create a nasty clog as the filaments can mix and then bind up because they heat at different temps. When I change from one filament type to another, I always cold pull a bit and also hot pull a few while also using an up and down motion to 'plunge' the material a bit. I then finish with cold pulls with a hot temp filament that will pull everything out.

HA! I did miss that part about the Fibreglass usage. LOL Thanks for pointing that out I truly did not know that. Idly muse away

OK, here is the system I use. Assumption 1: The printer has to read the materials it has been verified for. That is why they have recently added things like CPE+, PP, TPU, etc. to their firmware. Assumption 2: The material profiles you make and save are based on those previous firmware definitions. The purpose of the material profile is so that when you set a basic set of parameters, such as print temps, etc, it sets a group of variables that get plugged into the maths of the system when figuring warm up temps, cooling temps and such for your printing. Assumption 3: This will not override the built in 'move filament' or loading temps when using the filament. So, if you choose a material that goes to 250°C and your material wants to only be at 225°C, you may be cooking it a bit more than you would want. I choose my base material to start with based on the temps it will apply when loading, pre-heating cores and moving filament. Not the printing temps. Assumption 4: The material profiles are there to facilitate your ease of plugging in numbers for the print settings and work with the printing profile, not to set the printer to a new material type. Step 1. Choose material based on the closest setting required. Again, I choose based on the temp of loading, moving and core preheating. Step 2. Duplicate that Material and rename to new material and change settings. This also allows you to customize the color representation in the Cura screen. Step 3. As you choose a profile to start with in print settings (0.2mm or 0.15mm, etc), save that profile as well and use the two in conjunction. I usually name it something like this: T-Glase-PVA_0.2mm or if not with PVA, then T-Glase 0.2mm. And, I do use the name of the material and not a generic like "PETG" or such. Different brands and colors can present variances I do not want to guess at later. Step 4. With the filament defined in the software, it will only work during the printing cycles. This means you MUST choose the appropriate material that you used to duplicate from. For instance; if you have used CPE+ for PETG, then you must choose CPE+ on the machine when you load or select type. But, the rest of it is workable as a combo. Personally, I find this situation most palatable as it allows things to be sequestered into different areas of need and not put all the eggs in one basket, so to speak. I would like to be able to make my own machine profiles for materials so I could load a specific type not readily available, but it is an emerging system and I can be patient. I mean, heck, I started with computers that operated on only 33Khz (yes that low of speed) and required a math co-processor to function properly PLUS all sorts of other widgets and code writing to just get it to break 640K memory limits. So, I do have a different perspective than most.

That is what I do. And, I gots 5 GALLONS of da stuff waiting to be brushed on my build plates. If you are using PVA in your printing, that stuff is expensive and why waste it? Plus you have complete control over viscosity. As a bonus, I even have an extra thick container of da stuff so's that I can use it as a masking agent for painting.
