Can't use a number higher than 171 for backlash

When I enter a number higher than 171 (myFocuserPro2_2_4_2_5), it automatically change back to 171. Any number lower than 171 stays as is.

Is the maximum of backlashsteps 171? I need it to be 427.

Holy moses, how on earth do you arrive at 427?
Technically the max value should be 200.
Please change to firmware 280 and app 2427 and let me know if it is still 171.
Making the value larger than 250 is going to be problematic.

By using a stepper in 1/32 mode, a reduction of 2.5 and 1mm/rotation :) This is the focuser:

When I put the stepper in 1/16 it should be around 213. I'll try the firmware this weekend and let you know, Thanks!
