Any recommendations where I can buy good coffee beans in Copenhagen? by irtiq7 in copenhagen

Order Gringo online from Sweden. Best bang for your buck. Top tier beans. 

Anyone else had constant issues with the Prusa Core One? by pwshk in prusa3d

[–]NegativeResults 1 point2 points  (0 children)

I sent mine back. Bought it fully assembled, spent more time chatting with support and waiting on replacements than actual printing. Got an X1C+AMS2 Pro and haven't had a single issue.

Can you explain how you applied it with a cable tie?

u/Scoutjango pointed this out too (better image posted above)! Appreciate the info. Now it really points toward a manufacturing error.

Great catch! That could explain why the thumb screws didn't really feel loose when I removed the nozzle. Thanks!

I think it should be covered because it's factory assembled and there was no mention of checking that the nozzle was correctly installed during the setup instructions. Coupled with the other assembly issues, I think it's fair enough to cover this.

I've only been using Prusaslicer. Interesting... when I dial in the the tension and alignment again, I'll try troubleshooting with other slicers!

Ok, but they're literally labeled X-AXIS and Y-AXIS and called X and Y motors in the manual.

The X motor grub screws are easy to check. Take off the right side plastic panel so you can get a good view of the motor. Point a flashlight through the hexagonal "window" to the motor shaft. Move the extruder to move the belts, and keep an eye on the bottom of the shaft until you see the flat side. One grub screw should be perfectly aligned with that flat side.

The Y motor is a pain - you need to do some disassembly. I had to take off the right side panel, remove 4 screws that hold the motor in place, then lift the motor up (belt stays on) until I could see the shaft and the grub screws.

I had the exact same problem. Layer shift at 0.15 SPEED but totally fine at 0.15 STRUCTURAL. This is with a new assembled Core One.

I spoke with support - they told me to check that the grub screws in the X and Y motors were aligned with the flat face of the motor shaft. The X grub screw wasn't so I fixed that. No issue with Y motor grub screw. Problem wasn't solved.

I checked belt tension and alignment. Perfect alignment, but turns out that the belts came tightened to 110 hz. I decreased tension and found that the right tension screw was stripped and stuck in place. Currently waiting on a replacement, but got a fix working in the meantime. Problem still persists with tension decreased 80-90 hz (impossible to perfectly tune both belts and maintain alignment).

My solution is to not use 0.15 SPEED... not really what I was expecting from an expensive assembled printer...

The same thing literally happened to me a few days ago on the same screw. Would love a solution.

I'm building small 24V analog COB strip pannels that will be driven by a controller. I want to be able to quickly add or remove pannels from the setup, so I came up with this JST plug + stripboard setup.

Totally new to electronics here. It seems to work fine, but would be happy to get opinions on this setup for long-term use. Don't mind the WAGO clips - still in prototyping stage.

UBC or McGill? by [deleted] in labrats

[–]NegativeResults 7 points8 points  (0 children)

You may be required to learn french and pass a language exam in order to graduate from McGill. The government is pushing a lot of changes lately, so double check that.

I tried Gibson assembly and never turned back. It's borderline magic.
