Re: first second skips. My old old car had a shitty aftermarket Bluetooth stereo that, to “save power” or whatever, would stop transmitting after a period of silence. However, it’s definition of a “period” is very generous - a split second pause for effect in a song was enough to trigger the cutoff. So any songs that had that dramatic crescendo to silent sound would get a few extra seconds.
The… Whole printer? The only thing they changed are the hot end and the control board. The entire construction of the printer, including all of the linear motion components that make these things so rock solid, haven’t been touched. Swapping those two components out isn’t anywhere close to a “custom built printer”. Besides firmware, it’s 90% stock, and it’s trivial for someone with the expertise to get a klipper profile built for something like this.
