Design That Matters: Scaling Menstrual Product Dispensers Through 3D Printing
Menstrual products are essential — but providing them in public spaces is often an overlooked challenge. Students of the Faculty of Architecture at the Czech Technical University came up with design solutions in the form of elegant menstrual supply dispensers. But...

Massive MMU3 speed boost: New FW slashes filament change times + CORE One L MMU3 news
The MMU3 has been our workhorse for single-nozzle multi-material printing, and before it hands the baton to the upcoming INDX system, we wanted to give it one last significant upgrade. We usually design our hardware with some headroom, so it can...

As I place my latest order on the Prusa website, I catch myself scrolling through my order history, noticing how much printer prices have risen over time. They’re still excellent machines and fairly priced for what they offer, but inflation hasn’t played out the same way for both of us.
Just having a great day.
I loosened the z-axis trapezoidal nuts, and that did completely make the noise go away. Except now the printer won't level properly at all.
Naturally I assumed this was because the bed was too loose and there was too much play, so I tightened the screws in the nuts back up. That didn't fix anything, but did make the z-axis much louder.
Long story short, the thumbscrews that hold the nozzle in were way too loose.
Lubricated the z-axis screws and that completely made the noise go away. Didn't want to look for the Prusa lubricant, so I just used the Mobil stuff. Smells the same as the grease on the rods, so it's probably fine.
I am not a lawyer, but Kyle Mitchell is, and the OCLv1 sure seems like a mess
The post did point me to Kyle's very plain-language Parity License that really interests me. I wish there were a more hardware-friendly version.
Like, there is part of a reference to it on the Core One maintenance page. Apparently an older version of the page goes into detail about it.
It is allegedly suggested by Prusa support.
It is suggested for the XL, which has the same general construction as the Core One.
Today's #repair project was a Prusa Mini+ 3D printer. A friend's 14 years old son had indicated interest towards 3D printing and the friend wanted to give him a 3D printer as a birthday present. They're on a tight budget, so they ended up looking for a used one. I recommended a Prusa for their longevity and repairability.
The device was sold as "100% working" but when the friends asked me to check it, I instantly noticed the Y axis had a huge play in it. The part that holds the Y axis belt couldn't hold onto the belt's teeth any more and it was impossible to tighten it correctly. With no time to spare fighting with the seller and thanks to Prusa's mentality of 3D printing as much as possible of the parts, the model for the new part was freely available and it was just a matter for me to download and print a new one. After replacing it, the belt tightened as it should. After factory reset and calibrations later the device was ready to be wrapped for a young lad to just start printing out of the box.
Edit: I was sent a picture today (day later from this post) of the now 15 year old dude's first print, the printer had worked right out of the box!
I've been doing some research (i.e. watched part of a video for 3 minutes) and it seems like you can access the side filament sensor without removing the panel at all?
Mine doesn't work and it seems that the most common issue is that the pivot for the lever inside is too tight so it doesn't move properly.
The wheels on the bus go round and round, ...
Who can hear the sound of the motors by watching this image? :-)
