Mastering Ball Screws. Most inexpensive 3D printers use a type of lead screw to move some part of the printer in the vertical direction. A motor turns a threaded rod and that causes a nut to go up or down. The printer part rides on the nut. This works well, but it is slower than other drive mechanisms (which is why you don’t often see them on the horizontal parts of a printer).
Some cheap printers use common threaded rod, which is convenient, but prone to bad behavior since the rods are not always straight, the threads are subject to backlash, and the tolerances are not always the best. More sophisticated printers use ACME threaded rod or trapezoidal threaded rods. However, when lead screws aren’t good enough, mechanical designers turn to ball screws.
Misumi recently posted a few blog articles about ball screws. In general, The Misumi catalog, by the way, is a marvel of mechanical engineering toys. Kossel Clear Delta Arm Crash Sensor by lboucher. Hi All This simple hack uses some limit switches to monitor the arms on a delta printer. Should the print head ever crash for whatever reason, the printer would pause, instead of bashing the arms around for hours. Only had 2 crashes in 1.5 years, 1 i think was a power glitch, and the latest was the wires catching on the print itself. Fixed the wires by attaching them to one of the arms via rubber bands. The switches hook in electrically, by simply passing the filament sensor signal through each switch. I'm running Repetier version 0.92.9 for the jam detect feature. Working out well so far. Haven't printed Rev 2, but i think the angled section will help stiffen it up. This takes some PTEF tubing for 1.75mm and 3mm filament. Notes: I printed it solid, just to make it as strong as possible so i don't break it when lowering my enclosure over the whole printer.
Just started playing with PETG, that stuff is tough. Sonic 3D Printer Auto Bed Leveling Makes a Swoosh. 3D Printering: the final frontier. These are the voyages of another 3D printer hack. Its mission: to explore strange new ways of leveling a print bed. So far, we’ve had servo probes, Allen key probes, Z-sled probes, inductive and capacitive contactless switches, just to name a few. All of them allow a 3D printer to probe its print bed, calculate a correction plane or mesh, and compensate for its own inherent, time variant, inaccuracies. Capacitive distance switch by me These sensors are typically mounted somewhere on the print head and introduce their own sensor offset, which has to be precisely calibrated for the whole thing to work. Compelled by the idea of eliminating the last manual calibration step, I wanted to make Zortrax’s method of contact sensing compatible with non-conductive PEI, Garolite and glass build plates.

I’ve been playing around with magnetic encoders a lot lately in the hopes of getting some sort of error-detection system up and running. I think I’ve finally made some headway on it. I’ll start off with the video of where I’ve gotten too. It’s not much, but I think this system is worth exploring further. Apologies for the rather poor quality! In the video you can see me being rather abusive towards my printer – shoving the X axis around pretty heavily.
Sure, there’s still a defect present in the print from when I moved the axis, but the printer pretty quickly gets past this defect and the print returns to normal from there on. Of course, people usually don’t grab moving parts of their printer (I hope), so the example in the video is not a problem most printers would face. Overheating stepper drivers.
Nozzle getting snagged on print. Any other (momentarily) insufficient torque cases. Belt stretch / slip. Details On the printer / firmware side, I still have a lot of tweaking to do. Filament Width Sensor Prototype Version 3 by flipper. This is a prototype for an optical sensor that measures the width of plastic filament in real time as it goes into a 3D printer or a filament extruder. It is prototype #3 (other 2 are on Thingiverse as well ). The idea is that with a real-time width measurement the 3D printer could compensate the extruded flow for changes in filament width. Also if there is variation between spools of filament, there is no need to calibrate for that when slicing. The g-code is independent of the filament diameter. For filament extruders, the measured width can be used as feedback in the extrusion process.This version includes a custom designed pc board as well as a housing.
A version of Marlin is modified to use the sensor data. This prototype sensor is compatible with the design of the latest Lyman extruder. Updates in version 3: I improved the PC board to use screw terminals for the connections. I am selling a limited number of pc board kits at: Cohesion3D. New Part Day: Smoothie For RAMPS. When it comes to 3D printer controllers, there are two main schools of thought. The first group is RAMPS or RAMBo which are respectively a 3D printer controller ‘shield’ for the Arduino Mega and a stand-alone controller board. These boards have been the standard for DIY 3D printers for a very long time, and are the brains for quite a few printers from the biggest manufacturers. The other school of thought trundles down the path of ARM, with the most popular boards running the Smoothie firmware. There are advantages to running a printer with an ARM microcontroller, and the SmoothieBoard is fantastic.
Re-ARM for RAMPS — a Kickstarter that went live this week — is the middle ground between these two schools of thought. It’s a motherboard for RAMPS, but brings the power of a 32-bit LPC1768 ARM processor for all that smooth acceleration, fine control, and expansion abilities the SmoothieBoard brings. The idea of a smaller board running Smoothie is nothing new. New Part Day: Smoothie For RAMPS. Re-ARM for RAMPS, simple 32-bit upgrade by Roy Cortes.

Smoothie Project. Impressions: Duet vs. Smoothie - Welcome to the SeeMeCNC Forum. This is a comparison between the Smoothieboard and the Duet 0.8.5. I haven't used the Duet 0.6 or any of the other iterations. Hardware Capabilities The Duet has 96KB RAM, runs at 84MHz, and has five stepper axes (expandable to 9).
You can drive up to six extruders.Smoothie has 64KB RAM, runs at 120MHz, and has five stepper axes. There are no official or third-party expansion boards, so you're limited to two extruders max.Both boards have USB and Ethernet connectivity. Smoothie allows you to mount the SD card over USB, but transfer is slow, and an incomplete filesystem implementation means that you have to handle uploads in a very specific way in order to avoid corrupting the file allocation table. The Duet has no support for mounting the SD card over USB. Why I left Smoothie for the DuetIt has more RAM, and drives more axes. TB6600, Steppers, and Micro-stepping.

Congratulations, you have decided to build your own 3D printer! The process of building your own printer can be a bit daunting to some people, especially with so many choices out there. This article will compare different designs and parts and give tips on construction that will hopefully layout the tools and knowledge you need to know on how to build a 3D printer. Getting Started The first thing to do once you decide to build a printer is to decide what type of printer you want to build. This article will assume that you are building a FDM or plastic deposition type printer with three axis. Cartesian-based Printers Cartesian printers are the most common type of printer on the market and consist of three perpendicular axis that print on rectangular print areas.

Owning 3D printers with different nozzle diameters, I am able to give some first-hand experience on their advantage and disadvantage. Hope these could be helpful. FYI, my 0.4mm printer nozzle is from Up! 3D, and the 0.35mm is Type A Machine. Basically, nozzle of bigger diameter extrudes thicker strings, and vice versa. Things that don’t really matter:Filament material/size: You can buy any type of filament from the market as long as the machine takes. More rigid prints: When I drill a hole on the print, I feel more like drilling through a piece of tofu if it is printed with bigger nozzle diameter. My rules of thumb to choose which printer to use for a certain job is: Like this: Like Loading...

In "Mechanics" TweakTown's Guide to 3D Printing: Part 1 - What makes up a 3D Printer? 3D printing is all the rage at the moment. The ability to design or download an object and watch it form in front of your eyes is a very appealing thing to a lot of people. Up until a few years ago, printing physical objects in the third dimension was something that was just out of reach for the average consumer, with entry-level commercial machines costing tens of thousands of dollars.
One day in 2005 a professor at the University of Bath in the UK decided to change the 3D printing world forever. Dr. In this guide I am going to attempt to help you make sense of it all and hopefully guide you towards purchasing the best 3D printer that suits your needs. Before we get started we need to determine what kind of "Maker" are you?

If you are reading this article that means that you’ve probably decided to join the community of 3d printing enthusiasts and find out more about 3d printers, or maybe you have already got some experience in it and are ready to try to create your own 3d printer from scratch.
In this article you will find general understanding how 3D printers can be built as well as links to really useful resources where you can find more detailed information with step-by-step description. Currently there is a big variety of 3d printers in the Internet that already assembled and are ready to print right after you unpack them from a box, of course you also need to buy a 3d printer filament for it. Do not forget that not all 3d printers can use the same filament types, so please read the instruction before you purchase it.
But for some people who love to make something new with their own hands can be more interesting to build their own 3d printer from scratch. Good example of it is RepRap movement. Advice for a newcomer, Prusa vs. MendelMax : Reprap.

By Kalani Kirk Hausman, Richard Horne RepRap 3D printers use the popular open-source Arduino microcontrollers along with stepper motor controllers and motors and sensors for movement control. Some custom 3D printer boards integrate the Arduino’s functions with the related items typically found on a 3D printing “shield” that attaches to the basic format. The best of these boards are: RAMPS (RepRap Arduino Mega Pololu Shield): This is the original Arduino shield designed for multiple stepper motor control and for management of the extruder and built plate heaters.
It includes all the electronics needed for a RepRap in one small package for low cost. The design is modular and offers plug-in stepper drivers and extruder control electronics.RAMBo (RepRap Arduino-compatible Mother Board): The RAMBo is a modular all-in-one combination of the Arduino board and RAMPS shield. Geared: Some extruders include gears to slow the advance of filament and to gain greater control.
