cracked it.
it works in 16 bit, not 8 so it needs to be something like
gm convert -type grayscale -colors 256 -operator ALL AND 32768 -threshold 32767 (infile) (outfile)_8 gm convert -type grayscale -colors 256 -operator ALL AND 16384 -threshold 16383 (infile) (outfile)_7 gm convert -type grayscale -colors 256 -operator ALL AND 8192 -threshold 8191 (infile) (outfile)_6 gm convert -type grayscale -colors 256 -operator ALL AND 4096 -threshold 4095 (infile) (outfile)_5 gm convert -type grayscale -colors 256 -operator ALL AND 2048 -threshold 2047 (infile) (outfile)_4 gm convert -type grayscale -colors 256 -operator ALL AND 1024 -threshold 1023 (infile) (outfile)_3 gm convert -type grayscale -colors 256 -operator ALL AND 512 -threshold 511 (infile) (outfile)_2 gm convert -type grayscale -colors 256 -operator ALL AND 256 -threshold 255 (infile) (outfile)_1
Then the 8 files layered on top of each other in the cutter software with halving engrave depths on each one
