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…

First layer height problem after changing nozzle

I have a problem with my first layer height. But lets start at the beginning: I own a Tevo Tarantula Dual extruder printer with a endstop switch for Z axis. No Auto bed level. 0.4mm nozzle. Everything worked as it should. I home extruder with G28…

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…

Is it possible to use an aftermarket controller on a MakerBot?

I've got a dead MakerBot Replicator Dual and I'm not really interested in fixing it with about half the parts being proprietary, discontinued, and therefore very expensive. So, I'm wondering if it's possible to use a controller board used on some of…

Why is my filament pressed together at the nozzle

When I wanted to take out the filament from the extruder, it didn't wanna come out, it was stuck (even when I heated up the nozzle). So I unscrewed the nozzle and it looks like the filament is all pressed together at the top of the nozzle (see…

Apply X-offset to gcode (re-slicing not possible)

I am currently printing the QTrainer aircraft from 3DLabPrint on my Anet A8, via the supplied i3-compatible gcode files. So far, everything has printed fine, but the main undercarriage part tries to print off the left hand side of the bed by about…

Should I print in a well ventilated area?

With hot plastic being laid down layer after layer, I am worried about fumes. Should I only print in a well ventilated work space? Should I add additional ventilation?

3D scanner data acquisition

I found an old Creaform3D EXAscan laying around at the company I work for, and tried to plug it on a computer to see if it still works. I discovered that it uses a software called RapidForm for data acquisition, but its license is expired. I looked…

At which point does a delta 3d printer change the G-code in order to work in its non-cartesian design?

For example, to make a DIY cartesian 3d printer you could use/do the following: Create G-code using a program of your choice. Load it into Universal G-code Sender (GRBL). Pass it into an Arduino with GRBL. The arduino can pass the instructions to…
