Biehn, who had recently seen Taxi Driver and had aspirations about acting alongside the likes of Al Pacino, Robert De Niro and Robert Redford,[31] was originally skeptical, feeling the film was silly. After meeting with Cameron, Biehn stated that his...

This may sound like overkill but the unused connectors are intended to serve as ventilation holes and allow flexibility with respect to wiring needs.There are GX16 connector holes positioned so that wiring can go vertically down into the circuit card...

Depending on the type of screw head and length of the screw, you might need to insert the screws into the auger shaft AFTER it's in the hopper main body, through the hopper opening. As you insert the auger into the hopper, use a long hex driver to...

The robot has a ponderous gait.   PrintingGenerally I use a 0.25mm layer height and put about 1mm of plastic on the outside surfaces as a shell.  Since my printer has a 0.5mm nozzle I use 2 vertical shells and 4 horizontal top and...

You will need to make or look for a driver for the communication you want to use with the robot. I used a HC-05 bluetooth module for this. It has a simple UART channel with the board. You can use this app to send letters to the module from your phone...

There are GX16 connector holes positioned so that wiring can go vertically down into the circuit card driver connectors to minimize the wiring in the box to the drivers. I envision fans blowing in form the front and exhausting though all the unused...

When looping them on you may find it easier if you force open the key rings with a small screw driver to get them over the printed holes. Loop on the inner chains first. Make sure that they are put on in the same order they are arranged on the solid...

These fluorescent style LED lamps have internal drivers, eliminating external power components. The solid state design of the LED lamps give this fixture superior resistance to damage from vibration, extremes in temperature and a lamp service life...

When using the original hopper main body, this is showing how I install the screws with a long hex driver. Remember, start with the one nearest the tip, and test each one before moving to the next one! You can avoid this fiddly step if you print the...

Once it is on, center your tilt servo (again, I use a servo driver) then align the tilt to be as close to level as it can be, and press the servo arm into the groove and onto the servo gear, and secure it with its screw.Now all that is left is to...

... If anything you may have to change direction of your steppers for the Y-Axis if you're using the stock carriage - this can be done in the configuration. Edit: Updated link to the latest stable 1.1.1. ...I also have mesh bed leveling on as well.

Standard stepper motors such as Nema17 or 23 are proposed. Electronics, sensors, and software are covered in our GitHub pages. Improvements: Experience based on the initial prototype has shown that a punch (one or two) is required, which ideally...

Then assemble everything, install it on the printer (brush_mount.stl should be as close to the bed as possible) and use this piece of Start gcode for your prints (this is my complete start gcode, but the important part is only between Begin/End of...

The idea is to use the most accessible stepper motors possible, in this case the 28byj-48, modified to be used as bipolar motors. The control board used an Arduino mega with ramps 1.3 board and a discontinuous RepRap LCD display, the same ones...

One key feature is that it's completely compatible regardless of the Hemera-Mount used as long as the Hemera is oriented for the stepper motor on the right side. However, if you have an Ender 5 (Plus) or other Creality printers, you might want to...

Firmware setup To switch from the default Revolver to the servo version, go to the Settings->Steppers->Revolver menu and set Use Servo to Yes. Also, you have to define the On/Off positions of the servo in degrees in Servo open and Servo closed ...

Picked this “Hot-End” because it had all dimensions of the extruder and the possibilities for making the new setup a “Bowden” style filament feed with the direct drive extruder stepper motor mounted on the outside of the machine frame. Relocated the...

Finally this carriage also has the integrated belt tensioner system from Anukwolf Additional Printed Parts Needed: Joiner Clamps - 10mm - https://www.thingiverse.com/thing:2012264 Joiner Clamps - 8mm - https://www.thingiverse.com/thing:1752766 Belt...

* I've also had comms issues in the past and wanted to avoid the EMF interference of the bed and steppers. Thus the big ferrite on the USB, which sort of dictated this approach and the USB cable won't fit through the smaller hole. # Bits and Pieces...

I already designed an e3D-V& bowden extruder plate (labeled B), a Cyclops double extruder plate (labeled C), an engraving laser plate (labeled L) with support for electronic board and a sensor, if someone like me need it\nalso added an example of how...

This machine relies on 3/4 inch electrical conduit, 5/16 all-thread rods, NEMA 17 steppers, Ramps 1.4 boards, Arduino Mega controllers, and Marlin firmware. I initially wanted to be able to switch between a Dremel, router, 3D printer head, or laser...

I noticed many have had trouble with the firmware on this printer line, also by default the M500 command is disabled so PID and stepper tuning has to be placed in the startup script of the slicer for settings to be active. If by chance your M500...

**Update: 6/16/18** I just got a fresh set of 28BYJ-48 steppers, suspecting my old ones were weaker than normal. The new ones seem to have more torque and are resulting in fewer jams. Running them at 9v instead of 5v also helped eliminate jamming...

So at the end of the day it is a vast improvement, but like with most such mods you push out one limitation and put the pedal down only to find the next limitation waiting :) In the case of my AnyCubic Kossel, it's definitely the extruder followed...

I found a long 4-wire stepper cable which already had JST connectors that I was able to re-patch into the mainboard connections neatly. Wired in series with the existing NC end-stop by replacing the ground side wire. Output pin to end-stop, Ground to...

This project will bolt to a NEMA 17 stepper motor, and I plan to use it on my upcoming robot arm project where I'll try to make a fully 3D Printable robot arm with little to no metal hardware and preferably no bearings! I worked very hard to design...
