i had a similar problem once with unstable temp reading recall I re-flashed both the board and controller from mks  which solved it

Thanks for the idea, jinx.  I had been flashing through USB with Octoprint and the Firmware Updater plugin, so I gave it a shot through ISP headers with a raspberry pi (https://learn.adafruit.com/program-an-avr-or-arduino-using-raspberry-pi-gpio-pins/overview).  Everything worked, woohoo!  And then I unplugged the 6 pins on the ISP headers... and the problem was back >_<  As long as there's 5V and ground on those ISP pins, everything is great though so I'm going to work with that and try to make a cable harness to take it off the USB rail to feed those ISP pins.

me and my friend did just that, seems to help, a really hacky fix and i think it can be fixed another way but hell, we took an external power supply(5V phone charger) and put 5V to 5V and GND to GND on ICSP its somewhat fixed now +- 1C of fluctuation, seems this is noise issue, might be fixed by replacing some bad caps or making some caps bigger. we run Ender 3 24V power supply(stock) mks gen l 1.0 + 4xtmc2208(fysect)

Hello All from North Georgia, USA:

This is my first post on this forum...lots of good reading to be found here.

My question is regarding the MKS GEN L so I thought this would be a good place to post it rather than start a new thread.  MarlinFW config_adv.h sets the Controller_Fan_Pin to 4.  Is that D4 as shown on the board diagram at the start of this thread?  If so I suppose I would need a 5V fan connected across D4 and GND?

that would be a way may require a current limiting resistor! but not total sure on that. BUT I got gut feeling that may not work as expected. you thinking of triggering the fan using a servo command, you be constantly sending a servo pulse to the fan, would that not pulsate the fan? how will that effect to gcode  data while sending the servo pulse ?... think if I was doing this, I attach a fan to the 12V line  "(depending on the fan voltage you say 5V most fans I came across are 12V)" with a switch and switch it on when needed see next to the X axis driver there a 12V line to tap into or attach to the Hotend cooling fan so when you start printing your board cooler would kick in at the same time,,, if that makes sense

Thanks for your reply jinx.  It really wasn't my idea to use that particular pin, it's just the default pin used in the Marlin config_adv.h file for the MKS GEN L Board.  That bit of code allows you to set the controller fan (main board cooling) to only come on when the stepper drivers are on.  That fan is by far the loudest thing on my printer at this point and it would be nice to have it run as little as possible.  I'm not sure what the Marlin folks had in mind by using that particular pin.  I should note that I have a tenuous at best grasp of the Arduino IDE and Marlin FW.

I think it not so much the marlin dev but stems from the RAMPS development the gen l board is a single board RAMPS setup/pin layout and basically you can buy a fan adapter for that set of pins on the RAMPS

              

     link to  ali https://tinyurl.com/y3mbxu4b  but am not sure you be able to plug that onto gen L board.... So hows your tronic skills to could make a simple vero board and tranny to do the switching.


update: just thinking out loud here you could get that adapter and use some short jumper cables  8)

PS:
  dont go just plugin a fan V+ onto the d4 pin   the current draw could destroy the pin!

You are a wealth of knowledge jinx.  I may just order a couple of those to play with, although connecting the fan to the hotend fan is an acceptable (and easier solution).  On the subject of fans:  Are the ball bearing fans any more quiet than the sleeve bearing fans?

I got no answer to that I generally use whats in the parts bin. but read that Noctua brand are like the grail of quietness when it comes to fans. try and catch Bajdi in the SB sure he uses those noctua  on his printer...he have the answer :)) :))

I can confirm that Noctua fans are VERY quiet.

I use this in my 3D printer:
Noctua NF-A6x25 FLX
It is a pitty that they do not have 60x10 fans.

I use the
Noctua NH-D14
in my PC.

Also very quiet are these ones:

Hi all i have just recently got the mks gen l 1.o board and reprap full graphic smart controller screen.
I know absolutely nothing about programming or flashing firmware.
I have tried to follow this post and have clicked the link  https://github.com/makerbase-mks/MKS-TFT/tree/master/Firmware to get TFT 28 32English2.0.1.zip but its broken so i found TFT28_32_v3.0.3 Release file i have downloaded this and opened it found the classic folder but that only has 1 file in it mkstft28.bin i have uploaded this to my sd card and plugged in my screen and board added the sd card then powered on via the usb. the red light comes on blue light flashes but nothing happens to the screen.
Please help
If someone has a working firmware for this board with screen and bltouch configured can i get a copy to load up, would that work ??? im way out of my depth on this and drowning with all the youtube vids and web site info.
just found another post about the screen and smoothie but that said to switch cables around and cut out the back of the black ribbon holder - done that and powered up screen now lights up but i still dont as yet have anything on it.

hi,
first thing you got a link to the screen you have, you mention " reprap full graphic smart controller screen." then go on to describe using/uploading to a mks TFT screen,,, there two different screens

steps for the TFT:
open folder  MKS-TFT2.8-3.2,,History Version,, V_3.0.2,, TFT28_32_v3.0.2,,TFT28_32_v3.0.2 release file,,, Example
then open the folder Classic_En_Win8,, from there copy and paste the  four files to the SD card  Mks_font,Mks_pic,MKstft28.bin and finally mks_config... " just remember to edit it to your setup.

NOW if its the
 reprap full graphic smart controller screen you need to open the marlin config H file scroll down to line 1659
//#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
too
#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
but if you not done this before odds on you also need to add the U8glib library to the arduino EDI library

sorry dont know why it uploaded the image twice.
Finally found the file your on about in marlin 2.0  and loaded it to arduino 1.8.9 have done line 1659 removing the //# and added the u8glib u mentioned
do i now compile and upload to the board or save all the files (6) to sd card ??
lifes a bitch then u marry one.....
