For school use, your student, or co-students, will have a blast. And, for school use, it will be perfect as it has a good design for ease of use. My only complaint (and you really have to spend megabucks to overcome this) is that you need to tote a laptop when scanning. There are some good youtube videos on operation. But with the newer Sense 2 it is easier to work.

I have one. It is not bad. Not great. It is a good value. I would say it depends on the size of your scan target and the detail needed. Just know that in my research, I found that to get an appreciable amount of difference in quality required a jump in price of more than 5 times the cost. That was a year ago, and tech does evolve. To get a real difference, you are looking at a starting investment of about 9K USD. That would be the Artec Evo Light. Also know that the scanner has trouble with scanning anything below a certain darkness. Tried scanning some of my students and those with very dark hair, it would not pick up at all. And you also need to have good, ambient illumination. I have output to Cura and made prints and that was painless and it captures in a 1:1 scale ratio. But color scans are limited to the lower resolution it has in capturing the texture maps to be applied. But, not an issue if you are scanning for modeling only. So, scan resolution and ability to scan dark colors are the biggest thing you have to overcome. But, for what my goals are, I am happy with it and can always paint or powder a surface to overcome the dark color scan issue.

No...That's the clumsy noob at work. When I was a bit more green about some things, I had some build up around a nozzle. Bad build up. But I tried to get the fan guard open and it bent too much. Erin at fbrc8 told me how to fix it. But I bent it too much. And there, you have the story, The clumsy noob at work. I used to get test machines back in the day because I would tell people that I would really be able to test the ruggedness of their machines and software. But it works like a charm

And nobody even tried....oh well...Here is it before I get the supports off of it. I'll post a pic once the stand is printed and things are cleaned up. The Enterprise was the first ship that was not a flying saucer or tube style rocket. It was designed by Matt Jeffries. As an oddity, he designed it to be what we consider to be 'upside down'. It was Gene Roddenberry that flipped it over. The model was made from plans by Alan Sinclair and are recognized as the most accurate available. Especially since there there were actually three filming models. Link to plans with all the trimmings and versions

I put this up in a different thread, but thought it may be ok to have some fun with this. I am playing with different support settings and using towers and conical supports. Really funky patters it lays down. Can you figure out what this will be? It may be easy, mebbe not. Correct guess get's a Stan Lee 'No Prize' and a copy of the model when it gets put up as a new print....just like everybody else

This will be the last post I make unless I get another error. It seems to be printing ok with the old firmware on my machine. In the last third of a 30 hour print. But this is three successful in a row, so pretty darned happy. Has the Dev team figured out what could be happening? Here is the beginning of the print: What will it be? Correct guess get's a Stan Lee 'No Prize' and a copy of the model when it gets put up as a new print....just like everybody else Just a note: I will be changing service providers soon and there will be a blip in the images until my pointers are going in the right direction. Usually only for a few hours, but you know tech: It will fail at the most inopportune time.

I use a slurry of recycled PVA to put on the glass. My theory (and, someone correct me if I am wrong) is that it puts a layer that can dissolve away between the PETG and the glass. I have had not pullups or warps with this method. An alternative to the slurry I mentioned would be the glue stick or a 1:10 mix of PVA glue (White Glue/Elmers type) and water.

No problem. I will say it has the added benefit of being able to label and archive materials and special situations by exporting them. As for most correct, well, if it works and nobody else has a solution, well, there ya go

Definitely lower than PC. Glass transition is around 100 deg. C, Vicat softening around 96 deg. C. Thank you I wish these companies would be more forthcoming in their data/spec information.

Just finished the second print of 27.75 hours and it came out fine. So far, no stopping errors whereas before, it would die somewhere around 10 - 13 hours consistently.

I cannot find the glass transition temps. It is left blank on their spec sheet. How would this compare to Polycarbonate?

I just start with the basic presets and then configure based on the filament needs. This would include the flow amount for regular printing as well as the flow for the priming tower if you use one. Then go to the profile tab and click on the down arrow. You will see "Create Profile from custom settings/overrides." This is how I am making profiles for each material I test such as Ninjaflex, Semi-Flex, T-Glase, etc. Edit: this has been the case with Cura 2.3 and 2.4.

I know the new firmware and Cura will have many more materials (PC, TPU, etc) and is being optimized. Temperature is not the only concern when printing as chemical incompatibilities may keep things from sticking. Guessing on that one as I have experimented a lot with materials. Nylon works great as ABS does not. Temp difference is not that great. But, I am not eager to hop on betas as a clumsy noob. What are the new compatibilities concerning PVA as a support and other materials other than PLA and Nylon? PC is something I am looking at due to its high Tg temp (110°C - 113°C).

I have had my UM3+ since January and this has always been the behaviour. It is a bit odd that it floats across both extruders.

Finally got the print off. So far, this is the first print to go through at 26 hours. I have started the next print with 27.75 hours to print. To make clear, most of the errors I had this week were filament related. High humidity and other factors.

Ahhh, ok. I thought that may be what you meant. Thanks for making sure for me The only old and creaky electronic device in here is me.

I think it is quantum entanglement between our printers o_0 Spooky action at a distance strikes! LOL As for the other, thanks for the info. I am trying to piece this together as best I can and any information is good.

I am too new to give a definitive answer. But I find it usually has to do with either gunk under the nozzles (cleaned it and re-ran active leveling successfully) or when changing the glass plates, it can get knocked a bit. It is a springy board and that is why I got the extra glass plates. I can get one off easily, put on another and do a new active level. I have noticed that it is still good to do a manual level often as it will drift out of alignment or start to skew. Also, as glass is a difficult substance to manufacture with hyper accurate results, changing build plates should be manually leveled often anyway. I always do an active level after I manually level it. Mostly to check myself or get rid of any skewing that I did not notice. And, I have read that there are some glass plates that are not perfectly level too. I do tend to keep my thumbscrews close to full extension with just a little back off into a comfortable range of motion. Too tight in one direction or the other and it starts to get hard to turn.

I am not sure what you mean by electrically noisy area. Please explain. I'm in a basement apartment and I rarely get any cell signal here and about the only thing running close to me is my tv or computer. Upstairs people are rarely home. Printer is not connected to Wifi or USB cables. But currently, I am in hour17 of a 26 hour print and all is going well. I am happy about that.

No, what was happening before was that it would just stop. Nothing would happen or was operable. No error messages or anything. Just stopped working with only the ability to flip through the menus, but not operate anything. And the lights would dim as if it was in a resting state. It would require a complete shutdown and restart to get it back to any responsive state. What happened this time was that it had the error message and remained operable (i.e. it would lower the buildplate, display the message and lights remained on). But it would require a shutdown and restart to get the menu to operate. But the system remained operable (doing a proper stop action, for lack of a better term), whereas before it would not respond and the buildplate was at it's last location with the print head stopped, and glued, to the plastic where the error occurred. But I could manipulate the menu before. This time, menu was at error message only and no select-ability with wheel. Newer firmware (3.6) would stop all mechanical actions, but menu would move, but not activate.

OK, I finally got an error. Herer is what I postulate is or did happen: I have been getting communication print head errors. One is the Er18 and the other is an I2C. Keeping up with the other thread on the firmware and seeing the Linux overload issue (My words, inaccurate, but what I can surmise) may have not allowed the system to properly close out (lower build plate) and put up the notification. It took me this long to get a print that has gone for enough hours to cause an error. I was having serious issues with a filament that wanted to bind and grind or not stick with the PVA. Could have been a humidity issue. But changed filaments and this one lasted long enough. Took almost two days straight of failures on the filament to make me change it out..... Edit I am going to update the newest firmware version to see if this can be replicated. I have had the print head com issues before. That seems to be a running problem. Maybe not as I do not see a direct link to the 3.6.3 testing version.....so I continue to print.....I hope.

All settings and display are consistent. It is just an odd behaviour I noticed. And when I restart (usually because it will go into a slicing loop or just not slice at all) it seems to be more efficient. Times drop, a bit of pep in the step speed wise. And, maybe I just got a weird system.

Yeah, that was my mistake. I just figured that Star Trek would be that ubiquitous. Kinda lets you know just how geeky I really am in real life..... But, I do NOT own any uniforms......just some toys, models..., made my own Enterprise in 3D, did a flying animation of it going behind the launch bay of the space shuttle......hurrrrmmmm....mebbe the uniform is not so far fetched after all..... o_0 One day I will deconstruct my Enterprise Model (From the original series) and make prints of it.

Mebbe, mebbe not, but the context is different I am sure. Mayhaps, one a fun way to poke at and have an internal joke, and the other to malign.

I think the Jar Jar Binks comparison is off, but patents are there to protect people in this day when everybody thinks everything should be free, but fail to recognize that it is a business reality. And, yes, businesses can be good about it or bad. And without patents, there are patent trolls who will seek to take advantage because that is really their only business. Just like artists getting their work ripped off. Constantly. So, I think the patenting is a good idea and hopefully a patent pool of people will arise. So far, I think that I will take a wait and see how the company evolves. But I do think they need to take steps to protect themselves. You will know when the tide turns if it becomes a closed ecosystem like some others I researched and discarded because of the expense and limitations of 'only their filaments' among other things. Closed ecosystems tend to lead to dead-ends because they are not having to be competitive based off an established user base. Autodesk and Adobe would be a good example of lack of innovation compared to the smaller companies. Their user base allows them to not have to 'try' anymore, else they would not have to have subscription models. Shuffling menus around and throwing things on top of 30 year old architecture will fail sooner, rather than later. And, if they do turn to a closed ecosystem, then people are free to seek a different platform to operate on.
