Marlin 2.0.9.5 on Sanguinololu 1.3a (with D12 PWM FAN)

Hello,
After 13 years since I started with Huxley - PLA parts started to crack so I thought to renew old time construction by adding PWM fan and some other ideas to improve print possibilities.
From time to time I upgrade firmware to keep up to date with new functions etc. (I'm using Arduino IDE 2.2.1)

Last week I spent time struggling with such annoying error (attached config and config.adv files):

"In file included from ...\Marlin\src\inc\MarlinConfig.h:49:0,

exit status 1

Compilation error: #error "The selected board doesn't support enough user-controlled fans. Reduce NUM_M106_FANS.""

I'm sure that D12 works with fan (checked), D10 PIN is used by bed (version with Mosfet on heatbed PC but even with correctly set "pins_SANGUINOLOLU_11" I can't run M106 receiving "unknown command..."
My first thought was to comment out in "Sanitycheck...ini" line described in error message -> I was happy that compilation and upload passed until I tried M106 -> again with "unknown command..."

PLEASE - is there any one that could help me to solve this on 2.0.9.5 or eventually newer version of Marlin?

You have not defined a FAN_PIN

In provided pins_SANGUINOLOLU_11 you have

#if ENABLED(SANGUINOLOLU_V_1_2)
  #define HEATER_BED_PIN                      10  // (bed)
  #define X_ENABLE_PIN                        14
  #define Y_ENABLE_PIN                        14
  #define Z_ENABLE_PIN                        26
  #define E0_ENABLE_PIN                       14

  #if !defined(FAN_PIN) && ENABLED(LCD_I2C_PANELOLU2)
    #define FAN_PIN                            12  // Uses Transistor1 (PWM) on Panelolu2's Sanguino Adapter Board to drive the fan
  #endif
#else

The ENABLED(SANGUINOLOLU_V_1_2) is true but,
The #define FAN_PIN is never called as ENABLED(LCD_I2C_PANELOLU2) is false.

A second attempt is

#if !defined(FAN_PIN) && (MB(AZTEEG_X1, STB_11) || IS_MELZI)
  #define FAN_PIN                              12  // Works for Panelolu2 too
#endif

But once again (MB(AZTEEG_X1, STB_11) || IS_MELZI) is false, your not using one of these motherboards, so this is not called.


Simply add #define FAN_PIN 12 to your Configuration.h eg

#ifndef MOTHERBOARD
  #define MOTHERBOARD BOARD_SANGUINOLOLU_12
  #define FAN_PIN 12
#endif

The only change in pins_SANGUINOLOLU_11.h that is actually required and is being used is this on line 95

#define HEATER_BED_PIN                      10  // (bed)

as far as I can tell you don't have a display?

I have attached Upgraded to Marlin 2.1.2.2 Configs

you still need

#define HEATER_BED_PIN                      10  // (bed)

in Marlin/src/pins/sanguino/pins_SANGUINOLOLU_11.h


You should also try platformio under vscode, its is so much faster than Arduino IDE.

Thank you Dust,

Maybe it's a bit weird but I have spare LCD panel which I don't use to operate 3D printer, I prefer PC to start printing, etc. (using SD of course).

Adding "#define FAN_PIN 12" under board type in Configuration.h file solve my problem (looks so easy but wasn't for me )
M106 began to operate FAN but I had also to uncomment "#define FAN_SOFT_PWM" to be able to adjust voltage (M106 S0~255).

Speaking about platformio I tried to learn how to use it but for a guy without almost any skills with programing it was like magic so I'm happy that I still know how to use newer Arduino after swap from ver.1.0.5.

Now I can end up with board case project and slowly starts to collect prints, new rods and firmware tweaks to judge was it worth to re-new it like that .

Regards
Kamil
