Unfortunately this is a propitiatory machine i.e. chuck fitting , cutter speed, so I can't change anything.
The only thing I can do is look for an alternative supplier, someone has to make these cutters, they can't be that unique.
If they were more sensibly priced I wouldn't be spending my time trying to find the "holy grail"
If anyone is interested in key cutting to code this video link is the same as my machine
