I'm not entirely sure technically what the issue is, but this is what Keir said:

The issue is: (a) That HxC starts the first sector way too close to the write splice; (b) The trackdisk.device in Kickstart 1.x is fragile, it does not use the hardware to find 4489 sync marks but loads a non-aligned track and then searches manually. I image that the search does not like having the sync mark(s) only a few bitcells after the write splice.

Not sure what you mean, but Greaseweazle is designed in two parts - the Blue Pill hardware and a Python script running on the PC/Mac/Linux machine. So it can't be connected to any old machine/device. As long as you feed it a supported disk image file (currently only SCP) it will write it to the floppy disk.
