Line width changes depending on the direction the print head moves

I just re-ran all basic calibration steps from the Original Prusa i3 MK2 Manual. Now, when doing the first layer calibration, lines that are running in positive X direction are ok, while those running in negative X direction are severely…

Easy way to refine a 3D-model for 3D printing by removing internal geometry

I have been given a proprietary 3D file of a real world item from an item manufacturer with the obligations not to hand it out to anyone to produce a print in a low single digit percentge scale of the object. The object model I was handed was given…

Fix ghosting problem (damping versus bolting printer to a desk)

I have a Monoprice Maker Select v2. It is the kind where the moving plate (heat bed) provides the Y-axis and the moving extruder provides the X-axis. It has a fairly rigid sheet metal frame. In addition, I added steel rods has Z-braces. I see some…

How to calculate the strength of a printed object?

If I'm working with standard PLA, and I want to print a box that I can stand on without any risk of it breaking, is there any good way to calculate the appropriate print settings? I know that structural strength comes from the infill. Knowing this,…

Would a really short melt-zone be beneficial

IANAE (I am not an engineer), but I've been wondering: wouldn't it make more sense to limit the length of the melt-zone and hot-end as much as possible? I've been having a lot of problems with nylon causing jams inside the heat-block, this being the…

What can cause the build plate to slip?

2 days into a 5-day build, I came home from work and found the build ruined because the build plate had slipped. I'm using a Raise 3D N2 Plus printer, with the standard glass build plate that comes with it, attached via 4 clips: two stationary ones…

Perplexing Y-axis shifting problem - only in positive y direction, and only on moves of a very specific radius

I'm running a RepRap based ORDBOT Hadron on Repetier firmware version 1.0 that I built from a kit. I've slowly worked out the kinks but this one is an utter doozy. Basically I occasionally get shifting in the y-axis - the print bed moves on this…

Extruder clogs with HIPS

I've got a Prusa i3 MK3. I have printed with PLA, PETG and tried HIPS. Haven't had any clogs with PLA and PETG, but with HIPS I've got a weird problem. My first three test prints in HIPS went fine, but then I got a very bad clog (required total…

Hot end temperature varies during print

If I set temperature say 220 °C, printer heats up to it and it only varies +/- 0.5 °C under non operating condition. But if I start a print, there's a shift of +/- 15 °C. I've already auto tuned PID parameters and when I run M503, the printer shows…

Getting bumps/warts on surface, Cura doesn't want to comb?

I have not been able to print smooth and round shapes using Cura 3.3.1 (or earlier) without bumps. I think they are seams? The filament is PLA. Combing is enabled, which I thought makes it so that the nozzle travels over already printed areas,…

Nozzle heats while autoleveling (or before)

When I'm auto-leveling my Anet A8 with Marlin firmware, the nozzle heats to 195°C during the leveling process, which leaves drops of filament. I checked the resulting G-code but makes no sense to me: M107 M190 S55 ; set bed temperature and wait for…

Linking an Arduino Mega with RAMPS and an Arduino Uno with CNC Shield to control more stepper motors using Marlin firmware

I've been looking for this for a while, and it looks like no one has tried it before. Does anyone know if there is a way to link an Arduino Mega with RAMPS as master, with an Arduino Uno with a CNC Shield as slave, and get it to work on Marlin…
