Digital vs. analog pins

In the RAMPS v1.4 board, it seems like the X, Y, and Z motors all use at least one analog pin, while the extruder motors are entirely digital. See just the top left block of this photo: Is there any advantage to using analog vs. digital pins in the…

Arduino Mega 2560 + RAMPS voltage on GPIO pin

I am using an Arduino Mega 2560 and RAMSP 1.4 shield with Marlin firmware to control my machine (not exactly a 3D printer). Marlin has G-code: M42 P20 S255 ==> Turn on pin 20 of the microprocessor M42 P20 S0     ==> Turn off pin 20 of the…

What is an A4988 "twinner"?

As alluded to in this comment, under the question, Using dual Y stepper drivers on Marlin / RAMPS 1.4, there is a concept of an A4988 "twinner": I am rather building an A4988 "twinner" The question itself also mentions: ... add-on nanocard…

Can I mix TMC drivers with A4988 on the same RAMPS board?

The closest thing I can find is this wiki page that state DRV8825 and A4988 can be mixed. However, the TMCs seem different, requiring more connections and offer more features, so I wonder if they can be used on the same RAMPS board with A4988,…

Closed-loop stepper motors

I am thinking to use closed-loop stepper motors to prevent step loss and make the machine more accurate. What options (preferably low cost) are there for: stepper motor + driver + encoder + microcontoller Is building it from scratch worth it? E.g.…

Some steppers only rotate one way on RAMPS 1.4

I have a RAMPS 1.4 tester code for Arduino MEGA, only need stepper motors and drivers connected. The code in a working setup moves steppers in both directions but in my setup does something wrong: Extruder 0 , Axis X/Y only moves in 1 direction all…

Replacing RAMPS 1.4 for 1.6

During the assembly of my printer, I accidentally shorted the RAMPS 1.4 board, looking for a replacement I found the RAMPS 1.6 which would eliminate the need for a MOSFET power module. My question is, could I simply replace the RAMPS 1.4 for the 1.6…

Short circuit on RAMPS 1.6 board?

I have a RAMPS 1.6 board. After soldering my stepper drivers, I probed them for bridging and found a short where none should be. Digging deaper into it, my multimeter shows continuity between the 12V +/- connectors (on occasion). I have scanned the…

Will RAMPS able to control 4 stepper motors

I am making a DIY 3D printer based on the Prusa mini. So, I doubt whether RAMPS can control only 4 stepper motors as it has slots for 5 stepper motor slots and one will not be used in my case. If I can, in what order should I connect the drivers and…

Can I plug in Arduino Mega USB input (to supply power) and RAMPS 1.4 power input at the same time?

Can I plug Arduino Mega USB input (to supply power) and RAMPS 1.4 power input at the same time? This is because when I plug the PSU into the RAMPS 1.4 alone, the LCD keeps restarting and it just gets stuck at the Marlin logo but if I plug the USB to…
