Problem with merge request #190 ... #195

Good monring,

after you merge the #190 FAN 1 and FAN 2 stop working. (acording PCB):

imatge

I have reset this change and FAN 2 works again.

About FAN 1, Im not sure how to make it run.

Im using Robin Nano v3 and Marlin Color UI.

themacboy commented 3 years ago

Not sure if it is also related to #191

ProjectPatatoe commented 3 years ago

@themacboy Can you turn turn on FAN_SOFT_PWM to see if it fixes this? This setting can be uncommented in Configuration.h around line 2500. I don't have a second board to test with.

I am also using Robin Nano v3 and Color UI.

ProjectPatatoe commented 3 years ago

Also, Were both fans working and correctly assigned before? If it did, it would seem that your board doesn't match either of the three versions of the schematic. Were you using a precompiled marlin?

mmh on my robin nano v3 with github and MKS UI from 17.3 the fan works but only when i set ist to 128 and above. with 127 and lower it doesnt move. and everytime full speed

ProjectPatatoe commented 3 years ago

Yea I had the same problem with only on or off. I measured with an oscilloscope and found that the processor wasn't even putting out a PWM signal. This fixed for me once I turned on FAN_SOFT_PWM.

Before #190 Fan1(UI) controlled Fan2(physical) and Fan2(UI) controlled Fan1(physical)

themacboy commented 3 years ago

I just set:

define FAN_PIN PC14 // FAN0

define FAN1_PIN PB1 // FAN1

and fans are not working.

Then I set:

define FAN_SOFT_PWM

and fan still not working.

Then negative, that solution dint work for me. :(

ProjectPatatoe commented 3 years ago

under what combinations are working for people? The full working combination for me is

#define FAN_PIN PC14 // FAN0
#define FAN1_PIN PB1 // FAN1
#define FAN_SOFT_PWM

I am using platformio to compile

for me only work fan1 (fan2 acording pcb)

define FAN_PIN PB1 // FAN0

define FAN1_PIN PC14 // FAN1

In all other sets my fans din't work. Nothing

ProjectPatatoe commented 3 years ago

FINALLY I found the reason! The pins have actually been changed from revision 3.0.002 and 3.0.003. It seems that pins have actually changed as far I as can see. It probably should've been a 3.1 actually since it requires a different pins file.

Liriel-666 commented 3 years ago

ah thats explain why i had with the 02.02.21 github build Fan 1 on the Fan 2 Port. Now it correct and soft pwm works vor me until the Board goes black/dead with yesterday build

MKS-Sean commented 3 years ago

@Liriel-666 Is there any problem with the current version of the fan?

mmh that i mut enable soft pwn was in the github version from 18.3. but i can not test newer firmware because of that https://github.com/makerbase-mks/Mks-Robin-Nano-Marlin2.0-Firmware/issues/197

ProjectPatatoe commented 3 years ago

@Liriel-666 Which revision of the board are you using? Is it revision 001 or 002? It is on the back on the bottom right corner.

ProjectPatatoe commented 3 years ago

Because of the mismatched documentation on the hardware repo, I can't really tell if its revision 002 or 003 that changed the fan pin. https://github.com/makerbase-mks/MKS-Robin-Nano-V3.X/issues/14

its a 002 but with that https://github.com/makerbase-mks/Mks-Robin-Nano-Marlin2.0-Firmware/issues/197 its useless
