Once you have successfully scanned an object what you have is called a point cloud. This point cloud is not something you can just load up and 3D print.
As the name suggests it is simply a cloud of scanned point and not a printable closed 3D mesh. I am sure there are lots of ways and tools to turn the point cloud into a 3D closed printable mesh but my tool of choice is Meshlab which is free, open source and truly excellent :.
I would not admit to using or fully understanding every aspect of Meshlab and it can be quite daunting when you first start using it. I use the bits I need and try and understand as much as possible. So I thought I would include a step at the end of this instructable showing how I use MeshLab to convert the point cloud obtained from the scanner into a solid printable mesh and also transfer colour texture information from the scanned point cloud onto the mesh.
Transferring the colour maybe not be that useful if you are going to 3D print the scanned object but you might want to use the scan for some other purpose where colour from the original point cloud scan would be nice to have.
I have uploaded the results of the scan and post processing to my web space, feel free to download and have a look. Download : www.
This has been a great deal of fun to build and I think I have learn some new things which is the whole point. It is a good project as it covers many different areas - 3D printing, electronics, mechanics, optics, software, firmware, microprocessor control, 3D image manipulation and post processing. I am not sure how much I will use the scanner and for what purpose but that is not the point.
The point is to buy cool stuff, put it all together in order to learn new things and gain a few more skills. Please point out any inaccuracies or errors, I will correct.
Also please fire away with any comments or input as I would be very keen to hear what people think. Question 10 months ago on Step Desculpem, sou leigo no assunto e preciso de ajuda. Pesquisando pela internet percebi que tem placas Zun Scan que vem acompanhada com uma placa de driver A Good day.
Interesting project. Built by scanner, I downloaded the Horus 0. If the program does not start at all. I do not know where is the problem.
I will ask for advice. Well thank you. Tip 1 year ago. Reply 11 months ago. Hi there, Yes the motor has to run in the correct direction - clockwise I think. Silly question but have you gone to the software preferences and reversed the motor as the error message suggests?
The other option is that you can reverse any two of the motor wires and the direction will reverse. Has anyone gotten the software to actually run?
GitHub doesn't have any compiled releases either. Adafruit driver shield Ld driver shield CD Rom stepper motor. This is a code from Arduino libraries. Size: 3. You have to connect the stepper motor to driver shield. Motor will spin in full speed when the Arduino pin number 3 goes high. Review this guide for pinouts and example circuit diagrams for 3.
Since each bridge only uses one FET per leg now, the current capability is lower than the single monster H-bridge. The signal pin is connected only to the same control unit. Arduino 3. This is how to create a new Google Doc in a specific folder. Just copy and paste into the Arduino IDE. External circuit with microcontroller to drive dc motor Dc motor needs about mills amperes to mills amperes continuous current to rotate and move their spindle or shaft.
LN IN4 to Digital 7. I'll explain what it does, show its specs and share an Arduino project example that you can take and apply to your own projects. This is a robot that uses the two left and right joysticks on the PS3 controller to drive "tank-style. Here comes a keyestudio mini tank robot upgraded V2. No files in this folder. Here we include the needed library line 1 , define the number of LEDs line 2 , define the Arduino pin used line 4 , and define some strip specific settings line 8 like color order RGB, GRB etc.
Screw Driver Set 2. It has functions such as ultrasonic obstacle avoidance, bluetooth remotecontrol. Hold the Shift key on the keyboard and click Restart. These simple arduino projects are explained well and you can find the complete guide to DIY these projects with the help of circuit diagrams, source codes and videos.
In this kit, you can start with a step-by-step tutorial on building a robotic arm tank or visit 3D Models of 10 robotic projects. This project uses an Arduino to control a tank through a web page. Then, wire up the power and ground leads to the breadboard. However, before the trigger band sends out the ultrasonic signal, it must be created somehow using arduino code. When it comes to remote control robotics, or tele-operated machines as some robotics purists may call them, one of the most common drive systems is what is referred to as "Tank Drive".

Thanks Tom… I will send you an Email shortly. I also would like to be your beta tester. I am also prepared to pay for this. Hi Ben, thanks for the interest. I will send you email with details shortly. This would be perfect if it could use the DRV module. Can I be a beta tester or can you sell me a bare board or the files to have it made? Willing to give it a try.
Yes… I was looking at that option, but I was running out of room on the shield. I have added a little section on Beta testing. The Spindle pins are not on the same port as the stepper pins I however still think we need to work on adding I2C support to GRBL so that you can extend it with custom hardware till kingdom come.
I though about it a bit more. You might be able to get away with the current GRBL code as it is. It will take a bit of effort but its more than doable. Do you know by chance if Grbl recognizes M-codes, and specifically M1? Thanks Mark, I have sent you an email. Like your website by the way. Looking really nice. What sort of speeds can you get running a 3 axis machine? Hi Auzze… I have uploaded Version 2.
Please let me know how your project goes. Hi Id love to get this off you prepared to pay for it as well. Thanks… I have send you an email with the details. Hi Dustin. Is there a sign up for e-mail notification for finished boards?
Hi Daniel, I have sent you a quick email. Can you please explain the microstepping pins. Hi there…. Does that make sense? Hi Ron, Thanks for your support.
Hi Johan, Thanks for your interest. Dang missed out! Will you be doing another run of these? Hi Morgan, The new Version 3 boards are on their way and should be back in stock by the end of the week.
Is the v3 board available for sale yet? Can I buy the PCB only no components. Regards, Bertus. Goodbye messy wires! Thank you in advanced! Regards, Sven. Thanks in advance, Rene. The A version needs a 10K resister to make it work…. Can you please suggest a solution for this issue. Hi… There could be a few issues. Any suggestions? Hi, This is it! I found it out yestetday evenig. Hello there I have just started playing with the CNC shield version 3. Is this possible with the current shield? Am I missing something?
Kind Regards Marcel. Hi Marcel, Best would be to ask the above questions on the GRBL page as they will be able to advise what the best way would be to achieve this. I bought this board and want to clone the 4th axis to the Y axis. How is this done? Not sure about the name… But it works very well. Thanks for all great project!!!!!! Hi Jack, Yes, the boards I sell are gold plated. Hi Titus, The shield is a little more complex with it being able to control stepper motors.
Thanks in advance! Thanks James. Awesome design. Where can one buy this Arduino shield for the CNC and what would the shipping costs be? Hi, What end stops would you recomend?
Thanks for the great write up, very helpful. If yes, how? Christophe C. Thank you! Now everyone seems to use Ramps. Overall I was very happy with the board.
Eric A. I prefer the the Raspberry Pi version because its plug and play. Yes… It should be possible via the breakout pins on the left of the shield. Sounds possible if the pins can be readjusted in TinyG. Greetings, You have done a nice job with this board and the instructions. Thanks, Ron Wensley. Hi Ron. GRBL has hardware config files to config the Mega so it should work already.
Sorry… we are located on the other side of the world. Thanks, I have both and modules, so I will try them both out! Running 2. Hi, I have a grbl controller 3. Check your leads. GRBL has been sent to my arduino and the universal g code sender seems to see and connect to it. In any event, easy fix. How do I connect a larger motor which uses a controller? For example a MAH. Thanks Morten Stenbaek. Mount the props on the motors and check if the counter clock wise and clock wise props are in the right position as stated in the table below:.
Upload the hardware test program and open the Arduino serial monitor at baud. Send '1' via the serial monitor and wait for the response "Test motor 1 right front CCW. The numbers that are printed on the screen represents the amount of vibration measured by the accelerometer.
This is not a standardized value and should only be used to minimize the amount of vibration of your YMFC quadcopter. Hold the quadcopter firmly down, place the throttle in the lowest position and connect the flight battery. Now slowly increase the throttle until motor 1 starts to spin. Check the direction of rotation and that the prop produces upward thrust.
If the motor rotates in the wrong direction you need to switch two of the three motor wires. Put the throttle in the lowest position to stop the motor. Now hold the motor frame firmly in your hand and increase the throttle to half throttle. Check the numbers on the screen and also memorize the vibrations that you feel with you hand that is holding the motor frame. Stop the motor and put a small piece of tape on one of the blades and run the test again. Check if the vibrations reduce.
If nor try a piece of tape on the other blade. Keep doing this until the motor and prop run as smooth as possible. This can sometimes be a daunting task but the reward is a very stable flying quadcopter. So take your time and get it perfect! When you are done with motor 1, send a 'q' to quit and repeat the process for motors 2, 3 and 4.
YMFC balancing the propellers 2m16s. When you are convinced that everything is working as expected you can upload the flight controller software to the STM Don't connect the flight battery yet. Make sure to set the correct declination befor uploading the code. All the other settings can be ignored for now. Don't move the quadcopter during calibration fast blinking. The LEDs on the quadcopter should now start to blink according to the sequence as shown below.
After the startup sequence the flight controller information should be printed on the telemetry system. You can now test the flight mode switch and the heading lock switch. Go to the pitch and roll angle page on the telemetry receiver and check the angles of the quadcopter. By calibrating the accelerometer you can set the angles to zero when the quadcopter is level.
Calibrating the accelerometer is only needed after every upload of the code, the first build or after a crash. Place the quadcopter on a spirit level surface and move both sticks to the top left corner. After that the LED will blink, indicating that the calibration procedure is finished. If the accelerometer offset is to large an alarm is generated.
The compass calibration procedure needs to be executed: After every build. This software can be used with any Arduino board. Refer to the Getting Started page for Installation instructions. Active development of the Arduino software is hosted by GitHub. See the instructions for building the code. Latest release source code archives are available here.
