Yes, I’m more of a novice, but have already tried multiple pattern systems as well. An expensive digital one with loads of measurements superficially similar to this. Also Luterloh system with radial coordinates, but that just sizes you from one measurement.

Luterloh gave me an oddly sloped buttseam. I always have to lengthen sleeves, the custom sized does do that for me, but I also still had to adjust other stuff. Different from a commercial pattern but do still have to do some adjusting.

As for the printing, it’s the same as every other digital pattern. You either tape a whole bunch of A4 or Letter sized paper, or print in A1 or A0 roll. Freesewing is actually good at this, you can rearrange the pieces to fit whatever paper you will print on before saving as pdf.

Consider going to a tailor.

For fast easy machine single-serve, get a machine that takes beans. They cost about three pod-machines but they’re worth it. The pod-machines are cheaper because they come with vendor lock-in for the pods, and they just profit more on those instead.

Raid5 of three disks and keep the fourth as cold spare. That’s 16TB instead of 24, but you’re barely using your current 8, so a spare makes more sense.

You wouldn’t smell it if it was pure air. It’s VOCs from the inks, plastics, solder flux, thermal paste, etc
