Help with the firmware on RAMPS 1.4

Yes that’s the one you want.

Quoted from another thread:

So, here’s a breakdown of a RAMPS version:

MPCNC _Ramps_T8_16T_LCD_32step ==> obviously for the MPCNC, but also for the LowRider

MPCNC_ Ramps _T8_16T_LCD_32step ==> for RAMPS (other options are mRambo for miniRambo, Rambo for the full Rambo, ArchimX for well, Archim X=1 or 2)

MPCNC_Ramps_ T8 _16T_LCD_32step ==> T8 for the lead screw (you have the all thread, so you will need to adjust the steps/mm for the z-axis.

MPCNC_Ramps_T8_ 16T _LCD_32step ==> 16T for 16 tooth pulleys

MPCNC_Ramps_T8_16T_ LCD _32step ==> LCD is enabled, though I can’t recall which one, full graphics smart LCD or something like it

MPCNC_Ramps_T8_16T_LCD_ 32step ==> 32 microsteps selected for the stepper driver, typically for the DRV8825 drivers (A4988 stepper drivers are only capable of up to 16 microsteps)

Depending on your specific set-up (What stepper drivers do you have? Is your leadscrew a T8? Are you using lcd? Which one?), after you open Marlin.ino in Arduino you may need to change some things in the Configuration.h.

Also add the U8glib library - this is the library needed for graphics displays (The “how-to” is here: Marlin Firmware - V1 Engineering Documentation).

I can’t help with the specifics of editing the Configuration.h in your case because I’m an Arduino n00b and still working it out myself. It seems you can just go through the Configuration.h and change things to suit your setup. There are lots of comments and explanations of what each setting is for.
