Hi,
it works with the mill profile.
Spindle ratios are saved/stored as part of your profile. When you change a parameter that new value will have to be written to the profile, the .ini file.
Then the profile has to be read in order for the new value to be recognized.
Try changing the ratio, hit <apply>, which should cause the value to be written to the .ini file. Then restart Mach, the restart will ensure that the updated .ini
file is read.
Not saying this is the problem but I've encountered this behavior before and until I understood how the .ini file is updated and when it is read I would have sworn
Mach was faulty.
