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…

Ramps 1.4 and extruder

I have ToyRep printer (RepRap), with RAMPS 1.4 on the board. And I am powering in from ATX power supply with 12V. And the problem is it doesn't heat to 230(for ABS), max value was 173 degrees by Celsius. Is it bad extruder or not enough power?

Is it possible to 3D print shapes of atomic orbitals for a regular customer?

Disclaimer: I am not a professional 3D printer, so I'm not really familiar with how 3D printing works. I was thinking about trying to make a real life model of the atomic orbitals, to clearly see how the orbitals are really shaped. I thought about…

My print did not turn out as I expected. Where can I start troubleshooting?

I am trying to modify this thing. It's prints OK, but there are some design choices I don't like, so, since the previous makers uploaded their source files, I tried my hand at Sketchup. My latest round of changes have produced a weird phenomenon,…

Do I need to manually enter in gcode to turn off the bed and nozzle?

I got into 3D printing back when it was very much an art and not user friendly, and I have not been keeping up with it very much. My Slic3r profile required me to manually put in the GCODE to turn off the nozzle and bed. I'm experimenting with…

I am re-writing this question because, well, it needs to be updated. I have the Anet A6, but in a general sense of things, what kind of threads can I produce before it no longer works?

Centering model with CuraEngine when creating g-code?

How can I center a model at the middle of the printing area of the printer when creating a g-code with CuraEngine. Are there any parameters I can add to ultimaker2.def.json to achieve this? Thanks.

Temperature problems after switching to RAMPS 1.4

I recently switched to a RAMPS 1.4 on an Arduino Mega 2560. Ever since I have extruder temperature swings a couple of minutes into the print, but it looks like a problem reading the temp rather than actual fluctuations in the temperature (as can be…

3D Builder is Saying "One or more objects is invalidly defined"

Currently, 3D Builder is telling me "one or more objects are invalidly defined. Click here to repair." What is this and what does it mean? When I click it, it totally messes up my model (I can't tell what it even did due to the orthogonal camera).…
