E3D V6 underextruding always?

I have an E3D v6 1.75mm bowden. When I print, there is a gap between infill lines, and also when printing rectilinear/hexagonal infill lines seem to be pretty slim. My settings: Slicer: Slic3r Nozzle size: 0.4mm Print speed: 30mm/s First layer…

Best method to make dissolvable supports?

Sometimes supports are very difficult to remove (physically) when I print with ABS. The image below, from Thingiverse - MOF-5 unit cell, is after significant effort to remove the yellow ABS supports from a black ABS model. I've learned about…

Regarding the E-step in Cura

I'm using a Delta Wasp 2040 printer equipped with a clay extruder. I'm using Marlin firmware. I'm trying to print food (vegetable creams) not PLA filament, but my question is about the setting of some of the parameters. As reported in Marlin, the…

How can I insulate my thermistor?

I have had many problems with my heat shrink for the thermostat on my Anet A8 melting from the heat block. Is there a way I can insulate my wires from heat but still have enough room to put the thermistor into the block?

Can I repurpose the ISP pins in the lower right corner of the Melzi board?

Background: I have many years of experience with AVR and ARM Cortex PLCs and I feel very comfortable using them in projects but I am not an EE or SE. So, if I make a mistake or misunderstand something, keep that in mind. Thanks. I cracked open the…

Nozzle moves very slowly from home to start position

I´m currently working on a custom delta printer running Marlin 1.0.2 firmware. To control it I´m using the Repetier Host software with the onboard Cura software to slice my objects. The printing works fine but it takes the nozzle nearly 5 minutes to…

Alternatives to RepRap project?

I would like to print 3D desktop printer, but currently I know only RepRap project. Ideally I'm looking for some better quality or larger alternatives (e.g. for printing larger parts than RepRap allows). Are there any?

Can you print at 0.3 mm with a 0.2 mm nozzle?

I recently ordered some spare E3D 0.4 mm nozzles. However, there was a mix up at the factory and they delivered 0.2 mm nozzles instead. I usually print at 0.3 mm using a 0.4 mm nozzle. Can I still use the 0.2 mm nozzles to print at a resolution of…

Pronterface won't connect to my Anycubic Kossel Linear Plus

For the Anycubic Kossel Linear Plus I have to upload data to the 3D printer from a software called Arduino and then close it. Then I open Pronterface and put in the right port and baud rate that is in the Arduino files and then click "connect".…

How to switch motor outputs and use E1 as X, in Marlin firmware?

I broke up my electronics and now the output for X is not working. The stepper is OK. There is any simple solution to remap the output pins? I want the E1 output to act as the X output.

Having trouble getting first layer support to stick

I'm having an issue where the first layer of my support structures isn't sticking on the edges and causing the print to (eventually) fail. Any ideas on how I can fix it? I'm using Slic3r.

Printing shells and pouring filler

I had this idea for bulky parts for just printing the shell (PLA) then pouring in some kind of filler in to make up the bulk/strength. Printing bulk .2mm at a time line by line is slow and subject to warping! So I though precision print a shell and…

Embedding nuts and washers into print

I am creating a 3D printed part which will act as an attachment between a plate (actually a strain gauge) with two M2.5 bolts and a 2kg load with a single M4 bolt. I wouldn't be happy with tapping a screw thread into the print itself so I want to…

Difficulty getting good precision

I have a reprap printer with 0.3mm nozzle. It prints quite well, I am really surprised with quality of all the surfaces and the general precision of the parts printed. BUT I HAVE a problem: when making (for example) a 10mm x 10mm x 10mm cube with a…

Reprap variants with servo motors rather than stepper motors?

In a discussion about motors with a friend who used to work in the robotics industry, he told me that he despised stepper motor systems, as every stepper based system he had worked on required a bunch of hacky software fixes to make the system…
