drawing writing machine v2 cnc 2d plotter

The only way to get this process correct is by testing and correcting values. Heres a list of components needed for assembling this DIY CNC machine. Properly connect the coil wires to the stepper motor, i.e connect the two wires from the same coil to the [1A,1B] pin and other to [2A,2B] pin. Can you specify the length of the MGN15H linear rail? A homing procedure is essential for this pen plotter as the pen holders have a specific fixed position, so the machine must have a starting point. Arduino, according to the firmware help to generate steps/direction to the motor driver. For the printed part what setting did you use? We are setting up the other two steppers for the Y-axis. In this part i had found a bit problem with those slider which is attached to the slider (that white thing). I had not used Inkscape before, or any kind of machine like this, so it took me some time to learn to use it. Then the servo opens the gripper, it moves up 4 more mm, then move towards the pen in X direction and a little bit in Y direction. This depends on the type of stepper motor that we have, the selected step resolution and motion transmission, in this case the GT2 belt and pulley. For connecting the micro limit switches in place, I simple soldered wires directly to them, and on the other side soldered female pin headers which I got them from some jump wires. Wonderful work. so you dont have to upload any code to Arduino. If you have any questions feel free to ask them in the comments section below. If needed apply some grease on the rod so the platform gets much smoother movement. Take the two sides of the belt, attach it with the belt holder which we fixed already on the X-axis platform using two rectangle shaped aluminium piece. now the machine is working fine. It uses 3 NEMA 17 stepper motors for the X, Y and the Z axis motion, and a small servo for the gripper. If done with finding the correct position for the holder next tight it with thread screw, make sure that doesn't wobble.Insert the 0.5m smooth rod to the hole and double check whether the rod lies in straight between that two wooden frame. the parts will slowly melt and deform and become unusable. Next, I have recycled some parts of the old printer. cut the area to fit for the stepper motor. Detailing the power circuit, it is used to filter the input DC voltage to the expansion shield, has VCC output pins for Arduino VCC, Bluetooth module, Relay module, if you use it for future. All of the above problems are solved by using ABS plastic. As you can see your machine started moving. Please check the pin configuration of A4988 here, Check for the CNC expansion shield guide here, -> cnc exp-pin config-https://osoyoo.com/. The hole which acts as the axle for the pulley do not have more radius, better to have some tight while inserting After, screw it on the wooden block at the direct center of the motor,belt holder. Shipping cost, delivery date, and order total (including tax) shown at checkout. You can get the components needed for this project from the links below: So, we are using an Arduino UNO board in combination with a CNC Shield and three A4988 stepper drivers. Import the g-code file which you created.

Took me a while to figure out how things work, but seller provides prompt support. The pen plotter will start working and so we can enjoy watching it making magic. Whether we can put all these electronics into a box/enclosure ? The pen up and down servo motor stopped working after 4 months of use, and when I contacted maker q they told me that there is only 3 months warranty for the machine, so I paid for the servo motor (250 rs). Expecting more of this kind, Reply I actually ended up modifying this part a little but, no worries you will get the updated version of it in the download files. We can set the output size in mm, and in thecolorreplacing tap, we can remove the colors that we dont want to use. well i thought i can draw the school records using this great 2D machine. Used grbl v1.1h. I REALLY recommend this product. The product works great. These MGN15H rails provide very smooth and play free motion, as their sliding blocks have balls or rollers inside them. After warranty you have to pay for the parts. Now we are going to attach a pen holder on the slider. For defining the position of each pen, I used the offset values, which are 0 for the X and 277 for the Y axis in this case. I have used Arduino UNO, A4988 stepper motor driver, A4988 compatible CNC expansion shield. What is Cycloidal Driver? Then the gripper closes, lifts the pen up and move back to the same position before executing the script. I put just for an introduction. Software is crap and it wont work on Mac. click G-code utilities, Select MI G-code option. , Previous page of related Sponsored Products. Once we click the Kill Alarm button, on the serial monitor we will get a list of our current GRBL parameters. So this results into a closed loop all together. : Ok, next is the marriage or connecting the two axes together. As the Y-axis rail is unsupported on one side and the 3D printing PLA material itself is not that rigid, when fully extended, the pen lifter was 4mm lower compared to the supported side. PET might help with rigidity but still that wont be enough. Designing, 3D Printing and Testing, Amazing idea. For powering the machine, we need 12V power supply. As an Amazon Associate I earn from qualifying purchases. Carefully tight all four screws, because this is also one of the main part of this project Likely fix the another set of L bracket and stepper on the other side in equal height of the other set, straight to the belt holder of this side. Fix the aluminium channel on both side of that platform. I was actually surprised how good and precise the drawings came out, especially the ones where I used a 0.6mm gel pen. The brain of this CNC Pen plotter machine is an Arduino UNO board in combination with a CNC shield and three A4988 stepper drivers. Seems really awesome. ( all parts will be available ). We simply do that by securing the central plate to the X-axis sliding block using four M3 bolts. It can write with pens, permanent markers, pencils, and other writing implements to handle an endless variety of applications. I cannot download the files, This has happened on other ones too. Placing the DVD small stepper motor on that frame, screw it. Wish I spoke your language. To perform the tool change we must include a select and remove scripts, which are executed when the Tx M06 command appear. Plus, I recommend watching tutorials on Inks-cape on you-tube if you are not already familiar. Fantastic project ! And change the settings as your convenience. The construction of the machine is based on my DIY CNC Laser Engraver machine from my previous video where the goal was to make the simplest CNC machine with minimum parts possible. This innovation is amazing!!

Every time I comment on the other ones it just disappears (I commented three times on the SCARA robot) PLEASE HELP. The Arduino will be programmed by us. All rights reserved. Whats left to do now is to give life to it or make it a real CNC machine. As for the Z-axis, we have a simple reciprocating motion where the moving part slides up and down on two 6mm linear rods and suitable linear bearings. This thing is perfect! However, for this pen plotter we need a modified version of it, which can control the servo motor. This stepper is also a NEMA 17 but its shorter, 23mm instead of 40mm, in order to cut on weight. To begin with, lets have a look at the design of this CNC machine. The two main components are the MGN15H linear rails, together with their suitable sliding blocks. Since i am using Fusion 360 for first time, I took lots of time in designing some of the parts. To add the following enhancements to your purchase, choose a different seller. the use of a wooden frame and recycled parts are great. There few final touches that needs to be done in order to complete this pen plotter. Once the fixed part is secured in place, we can install the Z-axis stepper motor on it. I was able to write all 100 of my wedding thank you notes while working! At the bottom side of the fixed part, there are opening where we can insert M3 nuts and use them for securing the 6mm rods in place. Please note that the rod holder should be fixed in equal distance and proportion in both of the block. So we need something strong for the up-down movement, take a safety pin and bend it as shown in the picture, apply some force to bend, attach it to slider(the black platform) through that white holder and screw it, don't over tighten it, may have chance to break.Ensure that the motor is screwed properly.. We dont share your credit card details with third-party sellers, and we dont sell your information to others. Well, once you enter a comment it has to be manually approved in order to appear, but I simply dont have the time to do that for each comment. And you can use this machine to draw birthday cards, record drawing works,writing letters,decorating pages with your own ideas :). Its unique design features a writing head that extends beyond the machine, making it possible to draw on objects bigger than the machine itself. Here first we need to set the Pen up and down translation to be the Z-axis and set values for the Up and Down position. Ok, so lets take a look at the controller setup now. Works great. DIY, Wireless, Modular, Arduino, 3D Printed! After these steps test the slider by moving in opposite directions. I have been wondering why it is not done more on builds like these. Machine comes with 3 months warranty. Then we can install the lifter which is simply attached to the shaft of the stepper. In case any parts get damaged we will send a replacement parts without any cost. The x value after the letter T indicates the tool number from the tool table. The quality of the product is excellent, but the software is not beginner-friendly, The hardware works well. Because of the steppers are too small they may have chance to overheat, so i recommend you to fit some heat sink behind the motor, so this helps the motor to cooooool. If you want to improve the rigidity you definitely need one more support rail on the other side. Make sure all the axis are in position, be ready to turn the main power supply in case of any emergencies like crashing the axis, short circuits etc Open inkscape create the text or of your own, and then click "object to path" option from the sub menu. Screw it, tight it. Once we have the two sides ready, we can secure the X-axis linear rail to them with two bolts on each side. These above images shows the result of my 2D drawing machine. I hit a couple of bumps and WhatsApp for help. You will get an success message "Done uploding". place it on the position of your convenience for wiring. Iactually endedup lowering a bit this Z-axis limit switch, and as for the X and Y limit switches I used the ones from mypreviousproject which already had wires connected to them. First attach the smooth rod holder to wooden frame as shown in the image. In this step i am going to attach the main two wooden frame of this project. For powering we need 12v power supply with a minimum current rate of 2 amps.

I hope you setup your machine as shown in the first image. All right, so now we can start assembling the machine. MEandMine- Aha! And would printing with PET instead of PLA help with more rigidity? since i am using for first time, Only able to design some parts here. The most popular choice for DIY CNC machines is the open source GRBL firmware. Cheers! We should also set the parameter number 23, to 0, which tells where our limit switches are located, set the maximum feed rate, acceleration, maximum travel speed and the parameter number 1 to a value of 255, which keeps active the steppers all the time. product is good. You do have to be around to put the next page and hit go, but it is so much less time-consuming than doing it myself, and miles cheaper than hiring it out. You can find those added extension at inkscape's extension sub menu. I fixed directly up side of the smooth rod. Its more stable. And connect the output +12v to the PCB circuit, If you are connecting through your own made power circuit, before connecting make sure that the circuit do not have any short circuit lines. Then we can click on Create G-Code button and the G-code will be generated. Includes initial monthly payment and selected options. When I try to download the stl. So always using the one will helps to clear out the future heat related problems. Connect one end of the data cable to arduino and other to the PC/laptop serial port. All parts are printed in ABS plastic in 70C heated chamber which makes the 3d printed layer very strong.
