Ugly Bob

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.

In what way did they fail?

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.
