THre are three thing that can cause this Thermister, HotBed and Mosfet.
I would check all wiring to these areas, I would test the Thermister and Hotbed. then I would measure the Mosfet for a short with the Bed disconnected
I have done some modifications to my Controller Board. #1 was to add a simple heat-sink to the mosfets.
You will Note the I have install a single Aluminum Strip with Transistor mounting hardware to the four Mosfets, I have also enclosed the controller inside a Case with a cooling fan.
The case STL file is my design and is free to download

Other Items of good use for 3DP11

Keep me in the loop we can help you trouble shoot this problem

Yes there is On the Hictop Web Site here,
I would Install a Heat sink to all mosfets using a transistor mounting kit.
This controller is different It has the SD card Reader slot on the back, though will function about the same with the exception of the location of the SD card Reader.
I have purchased one though it has never been on a machine it is my Backup Controller.
You can also use an Arduino ATMega 2560 with a Ramps 1.6 this is what I am using on my MPCNC System
It appears that the original Controller without the SD Card Reader is no longer available.
If you never want to use the extra extruder you could also use the Ender Controller in a crunch or one of the CR10 controllers.
You would merely need to remove the standoffs drill new holes and install new standoffs to mount the controller.

Cliff if I flash the firmware that you kindly supplied me for the old controller to the new controller will I have to make modifications to the configuration file so that the SD card slot works on the new controller or will I just be able to use the one on the screen as normal ?
Hope that made sense.
I can do some tests here to see what happens, Though I believe you are correct.
A Quick power up using a USB cable shows me that the SD Card does work on controller and not the 2004LCD.
Will need to search for information to change from Controller SD card to the 2004LCD card reader.
Any suggestions from the forum would be most welcome. The controller we use is " #define MOTHERBOARD BOARD_MKS_BASE_14 "

Found this!
Now there must be a way around this, a way to swap External for onboard SD Reader Slot.
Schematic of 2004LCD shown below
It appears that the New Controller Circuit is close but wired to different Arduino Pins this means that I can change it.
Will look closer at pins_RAMPS.h section for SD Card Reader, as Both Controllers have the same pin-out for the EXP1 and EXP2 connectors.
Need to find how and where it selects the onboard SD Card Reader in lieu of the External SD Card Reader.

Note: It is new version HICTOP main board, it is compatible with 3DP08, 11, 12, 16, 17, 18 etc, but when you use this one you will need to insert the SD card into the card slot on the main board instead of the one on the LCD

Hi Cliff if you can work that schematic out that would be amazing.
I found our original post where you helped me with rebuilding my printer the 1st time around on a different site
which is here I am not sure if this is allowed to link to it but it shows the setup I have and I also downloaded the firmware that I lost that you kindly did for me last time.
If I was to take the configuration.h file from the old firmware and place it into the new v2 marlin would it still work ok ?
Old post link :
Just a side not I still didn't get round to doing the auto level sensor.

Ok after sitting there and switching the hot end on and off and then the heated bed on and off they both work as they should do, this is on the new controller board.
I then turned on the heated bed and hot end together and let the temps get to where I set them to. Then I turned on the part cooling fan.
As soon as the fan was switched on the heated bed temp began to rise. So i turned off everything and let the temps cool down and then only switched on the fan and the heated bed began to rise on it's own and kept going till i stopped it at 45c by turning the fan back off.
I double checked all the connections and they are correct, I even tried flashing the hictop firmware and it does the same thing.
I then unsoldered the heated bed terminal connector block (Green terminal Block) from the original controller that came with the printer and soldered wires directly to the VCC and the ground then used a normal electrical connector block and put the heated bed to the other side of it so it made a join.
Then I connected everything to the original board which still has the same marlin firmware that you kindly supplied me. Then using the terminal interface sent the M502 & M500 commands exactly as I did with the new controller so that everything is the same.
Turned on the part cooling fan and it worked as expected no heated bed temp rising, then turned it back off put the hot end on and then the part cooling fan it still worked as it should then I did both the heated bed and hot end and part cooling fan and it works exactly like it should do no temp increase on the heated bed at all.
So now I am totally and utterly happy, confused and disappointed as I don't have a scooby doo as to what on earth is making the new controller turn on the heated bed when the part cooling fan is turned on
Only thing I can think of is that maybe the new controller shares the same track for the heated bed as the part cooling fan and it is being told to turn on when the fan is active and that there is possibly a setting in the marlin firmware that has to be changed for it not to interfere with each other but I have absolutely no way of working that out as you know I don't understand the firmware.
What I understand about the firmware you could write on a pinhead and still have room.

Do I try the Marlin-1.1.9BF-v2.Zip on the new controller?
And Happy new year
