How to test Arduino Mega, RAMPS 1.4 and Full Graphic Smart Controller LCD?

Unfortunately, my extruder 8825 driver ended up fried. I guess this might have damaged the Arduino Mega and RAMPS Board. I tested the Arduino Mega and I'm pretty sure that it is fried too, so I bought a new one. I thought the MOSFETs on the RAMPS…

Steps per mm of extruder are incorrect after rebuilding

I have got a problem that after upgrading my printer to an aluminum frame my extruder went from around 400 steps per mm at 16 micro steps (which did match the manufacturer's recommendation perfectly) to a bit over 1000 steps per mm at 16 micro…

Why do nearly all cheap 3D printers have a Bowden extruder?

It seems that a Bowden extruder is the most used in all cheap 3D printers by far compared to Direct Drive that is very rare under 500 USD machines. But I haven't understood the reason, since in terms of hardware a direct drive doesn't seem to have…

Extruder motor not running during print job but working after I preheat the extruder and test it

I have a Prusa i3 (from FLSun). I have assembled the printer, calibrated it (fairly decently), and have successfully demonstrated extrusion manually. However, when I try to run a print job (the G-code clearly contains E commands), the extruder motor…

Extruder oozes filament out and slides build platform on contact with nozzle tip

If I am 3D printing on my Ender 3, and I pause the print, the extruder lets out more filament for like 2 seconds. This leaves a glob of dry filament on my print, which the could contact the nozzle tip, causing it to slide the build platform. I have…

Is there any (relatively simple) way to determine whether a stepper is being directed to move by the voltage signal across its winding?

This may be a long shot, but I was wondering if the signals seen across a stepper motor's windings could indicate whether the stepper was being told to move over some short time period. This is in particular for the stepper used on extruders. I've…

Plug simple stepper motor NEMA 17 on E2 slot of the main board on Creality CR10

I have build a Syringe Pump with a simple stepper motor (NEMA 17), and now I want to actuate it through my 3D printer. I successfully replaced the main extruder with it and it worked, although I had to still warm up the hot end as Marlin doesn't…
