As mentioned before there is work in progress on the forums with updating it. When I have more info on what changes there will be I will update everyone but for right now I do not want to say because its all being tested and it could change to something else if things don't go well enough. I also have all the feedback from the forum members on different things nad while keep those in mind, I will do what I can about adding those requests into the updated forum.

For the community side of things, 

There is a community hang out session tonight, May4th at 19:00 CET (13:00 EST / 10:00 PST) on our discord where community members can share their projects. I also asked Tommy for some different product updates that there are a few forum posts on, so there should be some info on the Open Tags and HT Hotends.

It will also be multi cast to our youtube and twitch channels, but if you want ot participate and show things off, you will have to join in the discord conversation.

Prusa Core One + Community Mod project.

The base and back are built and added some quality of life additions to it. I have an electrician getting one part set up for me and I need to order / make a insert press and then will work on the sides. When I can I will update the thread on the current update on that project and once it's done we can look at checking out some community mods to prusa slicer.

Now, to some who would ask why I made a single post with multiple updates... as you can see I am a wee bit busy with things but wanted to give an update  :) 

I checked the settings, and PLA is set to 215, why does it says 230 at the beginning of a print? Does it have to do with the default provided High-Flow nozzle?

This week I attempted my longest and most colourful print with disastrous results, a major layer shift after completing over 50% of the print.

I was attempting to print this.  lightning-mcqueen-kit-card-disney-pixar-cars-movie

I am running the latest firmware on both the C1 (6.5.3) and MMU3 (3.04)

I was using Tecor PLA+ from Inkstation. 

I used the "Generic PLA" profile in PrusaSlicer (2.9.4)

Could someone tell me what happened and how do I fix it?

thank you

Kind regards

I'm wondering why Sequential Printing doesn't also allow the option of printing the first layer of all objects first.

I've printed lots of sequential prints in a production environment, and I'm seeing a common issue that could be avoided. Normally, the first layer goes on perfect because it is laid down immediately after bed level sensing. However during a sequential print, that is only true for the first instance. The first layers of subsequent instances aren't guaranteed to adhere good because the bed shifts slightly over time because of heat. I see occasional failures,  and a lot of bad looking first layers because of this.

If the slicer had the option of laying down all of the first layers before starting sequential printing, this would fix the problem.

Edit: doing a quick google search, I see that this feature has been requested multiple times already by multiple people. One suggested the option of "print n layers first" and I think that's the most flexible solution. I also see that brims are already printed this way in sequential print mode, so the logic of that behavior should also apply to the object.

It lets you plot filament properties against each other in 2 or 3 dimensions, filter by property or material type, and compare things like strength, temperature resistance, price/kg, print settings, etc. Click any data-point and it takes you to the PDF data sheet. It turned out useful enough that I figured others here might be interested too.

For example, you could try plotting tensile strength vs impact strength vs deflection temperature with a price cap of $50 and you would find out PC is an interesting high performer.

Free, no account needed, no ads, and currently Prusa, Polymaker and Bambu Lab filament only.

Feedback welcome.

However, right from the first setup and calibration there were failures. The first attempt at purging filament failed, but then after 15mins started working. I got a small print done, but the next print shadow printed maybe at 1cm height. I couldn't unclog the nozzle, tried cold pulls, pushing through at 280c etc. Eventually I swapped the nozzle for a new one (I bought the advanced set) and it worked again for as short while but became blocked again after one small print. I'm using prusament Galaxy PLA. Through all of this I've been on chat with tech support. I've said I'm not particularly pleased with the it clogging all the time and not even purging on the first attempt, but keep being told, that stuck filament is a fact of life with 3D printing and I need to learn how to unclog. Fair there will be some maintenance required, but a complete clog every other print?! 

One support person in chat asked me to take the cover of the gears, but having not build the thing, I undid the three screws on the cover and pulled off the three layers, so now I have grease everywhere and a jumble of gears. He asked for a photo, which I sent, but didn't see anything odd and I asked why was I taking apart a fully assembled printer, and was told that there was not need to take it apart, they had just forgotten it was fully assembled. So I tried to follow the instructions to fit the gears back in, but don't have the alignment tool, because it doesn't come with fully assembled printers apparently. I eventually managed to put is extruder all back together. It's definitely useful to know how it all hangs together.

I was still having issues with not being able to print anything over 30mins without shadow printing, or else if I did a very quick print, the nozzle would be blocked the next time I tried a new print. I have spent so much time cold pulling and pushing acupuncture needles up the nozzle. 

Eventually I purchases an e3d ObXidian nozzle, and it seems to be better. at least the purge is reasonable straight, but sometimes needs a little help not to curl up. The original nozzles used to just make curls of filament to cover itself.

Printer is a little better now with the new nozzle, but now bed adhesion is a problem for some prints it seems.

I came here to see if people were having similar problems, and it seems I'm not completely alone. But I wondered if there was something else that I can look at with my printer to try to get consistent prints, so I can print and leave it rather than waiting for the next failure?  

Should I be looking at log files, is it a temp issue, could the motor have a fault etc. Any diagnostics I could be doing? Appreciate any help
