[BUG] FAN1 does not work

[LorenzoSaini]

I don't know if it is a bug related to my SKR PRO board, I downloaded the latest marlin 2.0.2 firmware, the issue is than i can't turn on FAN1 by "M106 P1 S255", i duble checked the configuration, configuration_adv and pins_btt_skr_pro_v1_1.h files, in marlin 2.0.1 work as expected.
I don't use Software PWM, Extruder autofan and FAN0 works fine.

Thanks for the replies.

i have found a solution, in conditionals_post.h. line 1221 and below
-Replace
#define HAS_FAN0 (PIN_EXISTS(FAN)) #define _HAS_FAN(P) (PIN_EXISTS(FAN_##P) && CONTROLLER_FAN_PIN != FAN_##P##_PIN && E0_AUTO_FAN_PIN != FAN_##P##_PIN && E1_AUTO_FAN_PIN != FAN_##P##_PIN && E2_AUTO_FAN_PIN != FAN_##P##_PIN && E3_AUTO_FAN_PIN != FAN_##P##_PIN && E4_AUTO_FAN_PIN != FAN_##P##_PIN && E5_AUTO_FAN_PIN != FAN_##P##_PIN && E6_AUTO_FAN_PIN != FAN_##P##_PIN && E7_AUTO_FAN_PIN != FAN_##P##_PIN) #define HAS_FAN1 _HAS_FAN(1) #define HAS_FAN2 _HAS_FAN(2) #define HAS_FAN3 _HAS_FAN(3) #define HAS_FAN4 _HAS_FAN(4) #define HAS_FAN5 _HAS_FAN(5) #define HAS_FAN6 _HAS_FAN(6) #define HAS_FAN7 _HAS_FAN(7) #define HAS_CONTROLLER_FAN (PIN_EXISTS(CONTROLLER_FAN))
With this From previous build:
#define HAS_FAN0 (PIN_EXISTS(FAN)) #define HAS_FAN1 (PIN_EXISTS(FAN1) && CONTROLLER_FAN_PIN != FAN1_PIN && E0_AUTO_FAN_PIN != FAN1_PIN && E1_AUTO_FAN_PIN != FAN1_PIN && E2_AUTO_FAN_PIN != FAN1_PIN && E3_AUTO_FAN_PIN != FAN1_PIN && E4_AUTO_FAN_PIN != FAN1_PIN && E5_AUTO_FAN_PIN != FAN1_PIN) #define HAS_FAN2 (PIN_EXISTS(FAN2) && CONTROLLER_FAN_PIN != FAN2_PIN && E0_AUTO_FAN_PIN != FAN2_PIN && E1_AUTO_FAN_PIN != FAN2_PIN && E2_AUTO_FAN_PIN != FAN2_PIN && E3_AUTO_FAN_PIN != FAN2_PIN && E4_AUTO_FAN_PIN != FAN2_PIN && E5_AUTO_FAN_PIN != FAN2_PIN) #define HAS_CONTROLLER_FAN (PIN_EXISTS(CONTROLLER_FAN))

Have you checked #16717? It should fix your issue

[boelle]

and bugfix 2.0.x should be working again, it had a few hours yesterday where it would not compile

[LorenzoSaini]

Yes, seems that #16717 has fixed the issue, thanks for the report, tomorrow i will test the bugfix branch.
