MKS Gen v1.4 -- cooling fan won't run
February 21, 2018 07:10AM
Hi,

I just replaced the board on my Anycubic delta with an MKS Gen v1.4, now I'm unable to get the PWM part cooling fan to run at all and I haven't found a solution on the forums yet. The fan is fine (and I've tried others), so I'm guessing it's a config problem. Could somebody see whether there's something amiss in my files please?

Thank you!

"#define MOTHERBOARD BOARD_RAMPS_14_EEB"

dont use this on a MKS Gen v1.4 , It doesnt know about the D7 mosfet...

use 

#define MOTHERBOARD BOARD_MKS_GEN_L

NB Power outputs will be EFBF or EFBE depending on number of hotends you set.

You did it again! Thanks Dust, I'd been pretty unsure about that one.

I appreciate your help, and all the time you must spend helping others!

I use:
"#define MOTHERBOARD BOARD_RAMPS_14_EFB"
on my MKS Gen 1.4 but that said I only have one hotend.

With:
"#define MOTHERBOARD BOARD_MKS_GEN_L"

Will all functions become available? Dual fan via fan extender, dual hotend?

Just curious as my setup works perfectly as is...

Yes indeed -- as soon as I made the change, I started seeing 2 fans on the LCD controller. I'd say make the change, Dust knows his stuff. smiling smiley

Yes he does smiling smiley

I don't have dual hotend, I was just curious.

The only reason I would like dual fan would be to control my heat brake cooler based on temp, noisy thing when the printer is just idling....

Yeah, that ought to be pretty straightforward if you change the above value as Dust suggests. Here's one way to do it,

Marlin Custom Fan Pins 3D Printer Firmware



Good luck! smiling smiley
