PLA as a raw material is really cheap - you can get it for as little as a few dollars a kilo - and a lot of the cost of a filament roll is just making the spool, packaging, and shipping it. In the end, the price difference between 250g and 1kg of PLA on a roll is rather tiny. Goes the other way too, you can buy 5kg rolls that come down to just $10-15/kg.
The same reason why a can of cola is so expensive compared to a big bottle.
And anything you write or upload to Lemmy should be considered permanent, as it immediately spreads throughout all the instances and they actually don’t have to respect edits or removals. And if instances defederate from each other then they simply can’t, as they don’t sync those requests any more - if Lemmy.World decided to defederate from Sopuli, this message would become permanent and I could not do anything about it.
Also check if you have TMC drivers and if they have Stealthchop enabled, it can cause these types of issues. Especially for the extruder motor.
Extrusion variance and bad tolerance filament will also exhibit the exact same looking issues, not just poor Z alignment.
Just to be sure, you have z-hop disabled? That can cause all kinds of issues if the gantry isn’t absolutely perfect.
Another thing would be making sure all variable line width printing options are disabled, I.e ones that try to fill gaps with thicker lines or print thinner lines faster to stretch the filament.
And finally, melt temperature oscillations, making sure every feature - outer/inner walls and infill - are printed at the exact same, slower, speed.
As for actual z issues, if the bed/gantry isn’t freely moving and has even a slight bind on the screws/axis, it can miss microsteps. One rather harsh troubleshooting tip is to reduce z-microstepping to a lower value, as that gives it more torque per step and usually you do not need the z to move anywhere near as gradually as some microstepping setups theoretically might allow.
Thingiverse at least tries to help a small bit, that’s why the remix functionality is disabled on the site for the benchy.
Fully 3d printed ones, yes. But you can print all the plastic parts of a Glock, buy a kit of parts that don’t require any verification at all and assemble a fully working one that is about as good as a genuine glock.
Or go a bit further with the FGC-9 or countless other similar things. The fewest actual gun parts used in successful firearms are in .22lr pepperboxes which use only barrel liners.
Here in Finland, I couldn’t do any of that, because barrels, liners, trigger assemblies, magazines, ammo, they all require a background check and having a license to own a firearm. As would those printed Glock upper/lower parts, if I had access to the kits making them illegal to own.
Instead of, you know, the 3d printer?
That “slicer file is public domain” part would probably not be valid as benchy has a “no derivatives” licence:
If you remix, transform, or build upon the material, you may not distribute the modified material.
That overrides the requirement of “share-alike”, meaning you have to use the same license for remixed or derived content, as you aren’t allowed to release any in the first place.
Unless the creator has received permission from them, of course - that overrides all licences.
The concept of the e-leveler is perfectly valid, I’ve used both a BLtouch and a dial indicator to basically do the same trimming setup multiple times, it’s just hilarious how visibly old school and bare bones he designed it to be and then he dares to ask $25 for one when you could literally cobble one together from parts for less than a dollar in five minutes.
It should have been a funny perk on like a PCB business card or ruler you’d get from him, and not product he actually tries to sell. Or at best, a kit costing barely more than the postage.
Only the original is public domain, what you do based on it isn’t.
To keep the example Disney, Alice in Wonderland, the book, is public domain. So is One Thousand and One Nights, the story Aladdin makes use of. The films Disney made adapting them are not.
You can create your own adaptation of the books, or even just reprint them as is, but you can’t resell or modify the Disney versions.
“Known for: ReiserFS, murder” kinda makes it sound like the dude invented both.
You did try drying it in a dehydrator before you did that, right?
Because I have spools almost that old, they print fine after a night in there. Brittle as dry spaghetti if I don’t though.
