I am using DRV8825 stepper driver. For 1/32 microsteps / step, I need to select 1 1 1 . But in RUMBA board, I see 3 switches which is covered by something. DO I need to remove the cover to select 1 1 1 from the switch? Or Are there any other method to select the 1 1 1 for 1/ 32 micro stepping?by mubarak111nsu - Controllers

I bought a new RepRaoDiscount Full Graphic Smart Controller few days ago for my RUMBA board. I have swaped the connectors of LCD and installed the u8glib 1.18.1 and enabled the command, #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER But still it was showing only green light like the attached Untitled-min. if it is connected with PC by USB port. If I remove the USB port, then it does not sby mubarak111nsu - Let's design something! (I've got an idea ...)
Dear respected sir, I am getting errors whenever I do some modification of Marlin firmware for Diamond extruder. I am using RUMBA board. Here is some of my modification, #define MOTHERBOARD BOARD_RUMBA Enable, #define SINGLENOZZLE as Diamond nozzle has single nozzle. There are 3 stepper for 3 extruder and that's why I have done following modification #define MIXING_EXTRUDER #if ENABLED(MIXINby mubarak111nsu - General

Dear respected friends, Hope all are in good health with success and happiness. I am making a big 3D printer using Rumba motherboard where I am using Nema 23 stepper motor which need 3 Amps. But, A4988 Driver can provide max 2 Amps current. That's why I am using TB6600 stepper motor driver. Therefore, I have to replace A4988 stepper driver pins with TB6600 stepper driver in RUMBA but I am facby mubarak111nsu - General
Dear respected sir, Hope you are in good health with success and happiness. I'm really happy for your awesome tutorials. But I'm facing a problem.
