My Creality K1 bed is actually in pretty good shape (max deviation of 0.7mm left to right, 0.1mm back to front), but I recognize that many folks might have beds that are off as much as 1.5 or more mm. The K1 has 3 lead screws, but not proper 3 point leveling (maybe someone will create a daughter board and a 3 point conversion kit in the future, after Creality open sources their firmware for the K1 series -- anyone out there that does this, I'd probably throw some small amount of money at you).
As far as I understand it, there are currently two methods to properly tram your bed:
-
Follow the creality way, which is essentially immobilize the bed with shipping screws and retension the belt that synchronizes the 3 Z screws. To do this, you must turn the printer on it's side, remove the bottom panel, and fight the tensioner. Reports are mixed luck doing this.
-
Skip teeth. You still have to do the bottom removal, but instead of completely removing the belt and detensioning, you slip the teeth on the belt drive (I think this is something like 0.4mm for each slipped tooth). There is less information about this, but there's a video in Chinese showing someone doing it. Perhaps a more helpful guide would democratize this more, and it might have more success than 1?
My question is: there are grub screws on the 3 lead screws, on the top side, accessible from the printer cabinet -- would it be possible to loosen the grub screws, so the z rod in that position spins freely, turn that z rod just slightly, then reseat the grub screw? That would seem a lot easier to relevel the bed, than doing either of the above procedures. Am I missing something?
Really feels like Israel is trying to do the old Russian misinformation game even on Lemmy these days to try and suppress blue votes on a single wedge issue because they know it’s the only way to get Trump elected and get more guns and bombs than they’re already getting, and they wouldn’t get pushback at all for Rafah or any warnings of any sort, just a blank check for wanton genocide.
Like I don’t like what’s happening in Palestine, but I don’t want to make it worse by pretending a non vote would somehow help them. Helping them would be ensuring that the party least likely to enable Israel the most is elected. That’s Joe Biden. Some people have ridiculous nicknames for him but my god wait until they make this look like restraint if Trump gets elected. Palestine would cease to exist almost immediately and Israel will de facto annex it, like Russia is trying to do in Ukraine.
So really you can vote to minimize the pain and suffering of Palestinians or you can not vote to minimize the pain and suffering of Palestinians. Personally I’m gonna vote to minimize the pain and suffering of Palestinians, and also support the environment (again not to the degree I desire), and support abortion access, and trans rights, and taxes for the wealthiest Americans, and, the list goes on, but yeah, I’m gonna vote for Joe Biden.
