Aquila Boards have issues with 3D/BL touch auto leveler

[classicrocker883]

the following is from a user who managed to get this to fix at this github repo

he enabled BLTOUCH_FORCE_SW_MODE for BLTOUCH,

add MB VOXELAB_AQUILA to HAL/STM32F1/timers.h so MF_TIMER_SERVO0 = 3

and Z_CLEARANCE_DEPLOY_PROBE 5

The good news! I've finally fixed the probe servo pin. Edited timers.h to have MF_TIMER_SERVO0 = 3, rather than 1. I don't understand why this works for Ender3 V2, since STM32F103R has the same mapping here. By default PB0 is bound to Timer3 and in board.cpp it's on &timer3 {&gpiob, &timer3, &adc1, 0, 3, 8}, /* PB0 */ image

Why in timers.h it gets #define MF_TIMER_SERVO0 1 // SERVO0 or BLTOUCH and how this suppose to work, I don't get. I can see in datasheet, that it can be redefined to TIMER1, but where and when this should happen? Anyway, deploy and stow now are working. The new battle is to make Z stop when the probe's shaft is pushed in. By now it doesn't stop.

Victory at last! So this 3D Touch sensor is totally now working in SW mode. The next weird thing was, that following this setting #define Z_CLEARANCE_DEPLOY_PROBE 10 when probing it raises the nozzle on by 10mm, then goes down by 5mm and throws error because it haven't found the bed. Changing this to #define Z_CLEARANCE_DEPLOY_PROBE 5 fixed this problem.
