Firmware 3.9.0 out now, info about new printers and more news

Many people were looking forward to the brand new firmware 3.9.0 for MK3/S and MK2.5/S and I’m happy to announce that the final version is finally available on our website. It took us a while, but there’s so much great stuff baked into the latest release. A huge thanks goes to our community members and collaborators, who helped us immensely! You have probably already seen the recent Dev Diary article, but in case you missed it, check it out. Our deepest thanks go to leptun, wavexx and 3d-gussner! Hats off to you, guys!

I also want to invite you to our live streams and share some more info about PrusaPrinters.org and Maker Faire Prague Online. So without further ado, let’s take a look at what’s going on!

Table of contents: Original Prusa XL and other production news

I’m pretty sure you wouldn’t let me continue without touching these two subjects first. We’re being asked constantly about new 3D printers. I guess that it doesn’t come as a surprise when I say that the current COVID-19 situation is causing major issues with shipping and sourcing parts. So even though we’re able to continue with the development of the “XL”, at this point, I don’t want to share any estimations, because they could lead to false hopes and the development process of the printer is not close to the finish. It all depends on how the current situation turns out in the near future.

The good news is that we have more time to tweak and optimize the entire machine. And some of the features might trickle down to the successor to the MK3S. And as always we will do our best to provide an upgrade path, when the time for a new version comes. 😉

And one more thing regarding production and shipping: within the COVID-19 situation, the demand for new printers (both MK3S and MINI) increased a lot. We had to hire more people and ramp up the production to cover the demand. This is why we had to temporarily stop the production of upgrades and focus on printers. However, all types of upgrades will be soon back along with MMU2S which is getting more and more popular. Also, we managed to get the shipping of small items back on track. During the COVID-19 pandemic, some of our team members had to stay at home (e.g. to look after their children), so there were some delays with shipping. However, we hired 12 new colleagues to the shipping department to deal with the queue. Now, if you buy one of the smaller in-stock items, we’ll ship them within 24 hours.

It’s an incredible amount of work – you can download new firmware 3.9.0 from our website and check the complete changelog on Github if you are interested in details about particular features and changes. I will point out just a few most interesting things…
