Today I will start my investigation into the fact that the Hictop Controllers are in fact a MKS BASE Shown Below.

This controller is a Ramps 1.4 Compatible controller but is a MKS Controller because it uses the Mosfet Pin 7 to power the 2nd extruder.

// Power outputs EFBF or EFBE
#define MOSFET_D_PIN 7

If what I believe is in fact true then by changing Marlin from.


This would indeed give me my 2nd extruder but this would also give me controls for a laser adapter

// M3/M4/M5 - Spindle/Laser Control
#define SPINDLE_LASER_ENABLE_PIN 15 // Pin should have a pullup!
#define SPINDLE_DIR_PIN 19

Asking for input from Hictop users if anyone knows for sure that I have come to the correct conclusion.

Took the honors an flashed onto a Old Controller that has a Bad Stepper Motor Driver

#define MOTHERBOARD BOARD_MKS_BASE_14 // MKS v1.4 A4982 stepper drivers

I started up with the setup of Extruder Fan Bed Fan, Tested the Fans and it controls both fans.
I can now flash one of my 3D Printers with this New Firmware Label "HicBlu MKS" this will tell me which version software is loaded.

" I think I have also learned that there are different A4982SLPT stepper motor Driver Chips "
" AS SHOWN Here in Marlin 2.0.0 Firmware module Boards"
"#define BOARD_MKS_BASE_14 404 // MKS v1.4 A4982 stepper drivers"
"#define BOARD_MKS_BASE_15 405 // MKS v1.5 with Allegro A4982 stepper drivers"

" So maybe I did not mess up on my soldering when I replaced the chip other than I purchased maybe the wrong chips "

If this is true maybe can change the firmware to fix.
