I have a k1c and have pretty much printed petg exclusively. Works fine. I know creality has an amazing clone... haven't used that.
Never tried it myself, but "functional print Friday" channel on YouTube uses IPA after printing with slow steady prying to remove stuck tpu. The IPA wicks under the print and releases it.
Get a load of this guy, he thinks the general will be in grenade range of where the action is!
I'm not sure how closely it satisfies all your requirements, but I have 2 ultimate hacking keyboards, and they serve me well. Open source firmware with clients for Windows Mac and Linux. Once settings are programmed into the keyboard, they work regardless of connected OS.
It's a 60% keyboard with no numpad... Ymmv.
The day you make something useful like those "genocidal tankie scum", I'll contribute to you too.
Make something better that people want to use or shut up.
Please also grace me with this python goodness.
It's supposed to be the easiest wood to carve for beginners, and it does carve quite nicely if you get the right variety. I bought some poor quality basswood off a no-name Amazon brand and it was quite tough.
Basswood. Got it off a guy on eBay.
I guess I'm lucky... My bed has <0.6mm deviation. I've had it for a couple of months printing almost every day and my biggest issue is an occasional layer shift.
