#To flash your firmware see https://www.thingiverse.com/thing:2783450 For more information and the links I got my info from see below: - https://www.thingiverse.com/thing:2783450 - http://3d-maker.info/switching-to-ramps-1-4-wiring-anettronxy/ -...

Electronics Early on, I decided to beef up the motors to NEMA23 and used Chinese TB6600 stepper motor drivers, which actually turned out to be TB67S109AFTG based. After some debugging it was found that the direction signal passed through a low speed...

While the calculation for the positon may be as accurate as possible, there is no feedback from the gauge and the cheap chinese voltmeters may not be the most accurate ones you can get. There are still some minor problems that I need to solve and I...

Repeat these steps four times ( two on each side). For you information, its the same design concept used in the PRUSA printer tensioner. There was no need to reinvent a great idea. Make sure belt teeth is pointing in the correct side, look at the...

I repeat to check the limit switch of the Z axis if it reads the profile correctly, should it be necessary to add washers behind the sensor to move it forward as needed. You will find attached, stl files, step files, and solidworks files, Italian and...

Repeat the process until you find the sweet spot that will lock the handle.*NEVER FORCE THE HANDLE ONCE IT LOCKS.* Retest the operation a few times to make sure everything is working correctly. Keep in mind without the Gear_Teeth_Stop you can...

  Just wedge something between the support (on the side) and the vertical wall under the overhang to get the front edge of the support to come inwards, repeat for the other side and then just pull them out with a pair of needle nose.   The'll pop...

I used small jewelers files and plenty of patience to perform this step.The model also uses threaded assembly thus an M8 by 1.25 tap and die will assist with thread cleaning if necessary.Assemble the Base.To assemble the base, I performed the...

Given this information, we repeatedly adjusted our inaccurate measurements through further inspection until the two clips overlapped perfectly. Our edits are shown below:</p><p>&nbsp;</p><p><img class="image_resized" style="width:47.26%;"...

This was determined by measurements, using the 'optimizer' feature in Microsoft Excel to determine the optimal arc angles and arc origins, printing to check the fit, and repeating until perfect. It took 3 iterations. I published the initial version...

Repeat for the other side. The head_bottom is super glued to the main body. The main_body is mounted to the frame with the body_fastener and a 2mm X 8mm screw. You have to have your wiring so it extentds through the head_bottom and allows access to...

Repeat this process with the orher hand of course. Now cut a sufficient length of thick copper wire that can be bent to lead from the hand through the hoodie and the base. You should cut a little bit longer than you need because you can cut to the...

Increased detalization, as well as worked out small technical details in order to maximize the repeat of the game analog model.4. This update was divided into 4 versions, for comfortable printing on different types of printers. The SLS version...

Black pegs mean that one of the guessed pegs is correct, and is in the right hole. Repeat with the next row. Continue until the binding pattern is solved. Once you get all 4 black answer pegs you win! Congratulations! You saved your patient by...

By repeating this simple pattern, I could fully attach the threaded parts without using too much force even for woodfills. Then again, another solution to the tightness would be to scale one of the parts by 1-3% in X and Y direction (you can easily...

// Filament can be extruded repeatedly from the Filament Change menu // until extrusion is consistent, and to purge old filament. #define ADVANCED_PAUSE_RESUME_PRIME 0 // (mm) Extra distance to prime nozzle after returning from park. // Filament...

It also is easily sandable.I spread it in a heavy layer while pushing it into the recesses.Its important to do this on the top and bottom halves while they are separate, you don't want to fill the gap between the top and bottom halves.Once its dry,...

Repeat this procedure until the strand out of the nozzle gets pure. Then calculate the volume with following formula Volume = (FilamentDiameter / 2)² * PI * PurgeLength Under the Tab “Plater” click on the button “Purging Volumes” on the right...

14) Repeat Steps "4" through "13" for the opposing side. 15) Once both sides are done Tighten up the screws you loosened on the Metal X-Axis Bracket. 16) The next step depends on if you did this mod laying flat on the table or mounted on the wall. So...

When the probe tip touches the bed the screw "sensor" moves up against the spring pressure and no longer touches the washer. Because wires are attached to both the washer and the spring, this movement causes normally closed contacts to open. When the...

Repeat for second LED. Install a short (2 inch) wire onto the board + for the switch, and a long (8 inch) onto - for the bulb. Tack down the board with hot glue or silicone on a top edge, or CA underneath. Install the switch. Solder the other...

As a probe for the board surface sensor, the most common antenna from a radio receiver with a screw thread at its base is used, which can be bought at any radio store the project of vacuum tweezers "NATASHA-1" will not be described in this article,...

The knocker is larger than the gap+piezo disk recess so there is some pre-loaded pressure on the disk giving pretty repeatable results as well as holding the motor firmly enough to prevent any negative impacts on print quality. Once you get...

It needs to be printed with a filament that is strong and that can repeatedly take threaded screws. This means PLA is fine, normal PETG probably won't as it's too flexible. For best results, Carbon Fibre filled PLA or even better, CF filled PETG do...

I repeatedly installed the bearing to be snug enough that it would scratch the steering tube, then removed the bearing and sanded just to remove the scratch marks it left behind. This way the sanding wouldn't make the steerer egg-shaped. After...

It also allows you to “home” the machine so you can get repeatable and consistent machine coordinates. **Materials Required** - 1 sheet of 6 mm (5.5 mm) cast acrylic which is at least 90 x 110 mm ([Amazon](https://amzn.to/3jVsjgN)) - 1...

A VERY LONG DAY, with lots of looking at ‘Youtubers’ who had the skills I needed, sometimes repeatedly watching the same video!Hope you Enjoy the final product.&nbsp;I have previously used a 3D printed hexagonal rod, which you can vary the length...

To restore the internal screen, repeat this operation. 2) OSMC for audio playback. Note that OSMC have its own Android app called "Kore" which allows you to use your mobile phone as a universal remote to have a full control on OSMC for Raspberry ...

Repeat until you have the needed number of segments. With all of the segments prepared take the 38mm solid center ring and feed each segment on at the broken link. After putting each link on the ring take your pliers and close the broken link to fix...
