all the inputs were processed by arduino nano and give command to stepper motor to feed required length of wire and instruct to servo to make cut of required quantity. Those americans. The diode shines the light through the window in the inlet terminal. It also does some basic scripting and calculations, has some variables and the bigger models also have storage for images I think. You could potentially get away with using just 1 or weaker motor if you use bigger and sharper blades. The wire travels through a tube, which can be shifted left and right via a servo to position it in the stripping or cutting section of the jaws. i actually have a lot of stuff for this already might build it, two questions: a) how do you think it would fare with stranded wires? I will definitely borrow couple of ideas from this build. You have declined cookies. The machine is very well built; It is clear that the author put great effort on the project and made it all worth, but what really catches the eye is the mechanism provided by the servo to displace the wire to either slice or cut. Simple 18dof Hexapod, Arduino nano (optionally with pololu maestro), LORAWAN GATEWAY FOR THE INTERNET OF THINGS. Calculates required wire length to perform the task. The ESP-12 (ESP8266) module runs the ESP-Link firmware and is used as a Wifi/Serial bridge. Additional LEDs and prototyping area on the PCB. Stepper | Servo | Display/GUI | Keypad | Button | Buzzer | EEPROM| Program. For the base of the machine I used 3MM thick white acrylic sheet, I drill some hole on sheet to mount PCB, Stepper motor with extruder set, cutter & servo motor for better idea please watch video it will give a idea how to mount those components on sheet all the components are tightly mount on the sheet now we can move to program our arduino, Now connect the 12V DC at terminal of PCB this is for stepper motor and connect USB to arduino nano this will feed power to arduino itself and servo motor now machine is ready to perform you need to press those push buttons to navigate between screen and to select desire data hope you will like my this project, IBASE Technology Inc., a world leader in the manufacture of embedded boards and industrial computing, Do you edit? A thin 0.5mm ABS sheet, available at hobby/model making stores makes a nice cover plate. We'll assume you're ok with this, but you can opt-out if you wish. This is awesome!! Normally the ESP's UART is routed to the PSoC's UART to operate the command console. Cant tell you the sheer number of times I come across a technology on the internet or real life, and I see a hackaday article about it the next day, Great build and well documented! Beautiful high precision machines with impressive speeds. The Trinamic Silent StepStick is controlled via SPI, for the A4988 driver, the microstep setting is set with jumpers and the motor current with the onboard trimpot. If theyre not pre-tinned, which is of course the best, keeping the insulation on them prevents the wire ends from fraying during transit. Well, This is one of the first projects I have made with Arduino. The stepper driver selection is done automatically at startup. Basically there are 3 process level of this machine like, Input like wire length and wire quantity provided by pressing push button also the real time data can read on 16 X 2 LCD. I used the Knipex stripper replacement blades, I got them from Amazon right here. The simplest method to upload the firmware without installing all the PSoC Creator IDE is to use the PSoC Programmer software, available from Cypress site. A custom PCB links things together electronics-wise. Andrey Skvortsov liked PERSEUS-9 homemade mobile 6502 computer. I absolutely love it, especially the precision nicking of the insulation without removing it. They were paranoid about reliability, One of the requirements was zero rats-nesting of the wire strands. Once started, the job can be paused, resumed or aborted. If there is a 3.3V voltage detected on the programmer port, the ESP's UART lines are redirected to the programmer header. Of course, having a PSoC onboard I wanted to make use of the hardware blocks and construct a stepper driver out of a PWM and counter components. Dead Spider Becomes Robot Gripper: Its Necrobotics! The type of the stepper motor drive can be set using the jumpers. Yeah, it takes serial commands and the displays fields / pages / controls accordingly. The display i used has a small onboard 3VDC linear regulator. I used that voltage to set the output level of the 74LVC4245 octal transceiver. 4 quick access presets for most often used jobs. Things I added were: and ESP-12 (ESP8266) module, Cypress EZ-BLE module (Bluetooth low energy), a few LEDs and a prototyping area with 3.3V, 5V and GND power rails. Cool rig. Added a stripped version of the system font, consisting of symbols 0x200x7F, thus saving the flash space. As other handlers, this one also works in a non blocking manner. Bottom view of the PCB. A DC-DC converter module provides the main 5VDC rail and the 3.3V one is generated with a linear regulator. dude- awesome project and great video. However, I think this is due to using very small and weak blades. I made a cover out of a thick transparent foil formed with a hot air gun. Do you Game? Irony for me is I work for one of the top US wire producers, but have no access to that expertise because I work in a different division. I'm using lots of short terminals made of solid 1mm copper wire in my builds. Make 10 interchangeable cartridges for different colored wire. Moritz Walter for his Arduino TMC2130 library, on which the driver is based on. Write for various publications, including Hackster. This website uses cookies to manage authentication, navigation, and other functions. The MP1584 based DC-DC step-down module has a max. By using our website, you agree that we can place these types of cookies on your device. This is exactly the type of community I want to build, people coming up with amazing ideas to improve the projects which eventually projects will be built based on all viewers ideas/comments. A box or a bag of pre cut stranded wires with the insulation removed looks like a bag of brushes after any handling. As far as i know, the best and most economic way to get a PSoC programmer today is to get one of the CYCKIT-059 PSoC 5LP dev kits, containing a nice 5LP MCU to play with and a fully featured programmer/debugger: KitProg as a little snap off board. Do you design? The compiled HEX file is provided in the github repository (/software/hex). Implemented, but commented out interrupt trigger. This decision can be reversed. That explains a lot of my experiences doing hand production in the lab. Choosing between cutting and stripping is a matter of aiming the wire for different areas on the cutters jaws, which is done with a hobby servo that bends the guide tube. Prior sending any data to the EEPROM, the hardware SPI CS line is set to a non used channel, as we don't want to access the display or the TMC2130, the software brings down the EEPROM's CS line and after the transmission is completed, CS is set to high and the hardware SPI channel is set back to default, most often used value: the display. In addition, these bytes can be sent in patterns, creating a crude, yet useful acoustic signaling block (anyone remember ProTracker on Amiga? Getting it to work on Mac and Linux requires using a virtual windows machine (ie. However, I was curious if I could change the UART baudrate on the fly (well, almost, between fully sent bytes), thus creating an acceleration and deceleration phases. UART is set to 8 bit of data, one stop bit and no parity (8N1). Maximiliano Palay has updated the project titled Bionic prosthesis. It will allow you to pretty much make anything you want :) It's fairly easy to get into as well. To operate silently the preferred voltage would be at around 20VDC. Alternatively, the fimware can be uploaded after opening and rebuilding the PSoC Creator project: Unfortunately the PSoC Creator and Programmer software is not multi platform and runs on windows only. New version of the reVOLVER sampler/looper pedal. Or instead, you build a machine like the one shown here by Mr Innovative to do it for you. This may actually make me buy a 3d printer Do it! Further, you represent that you will take such steps as may be reasonably necessary or required by applicable law to keep the product out of the hands of minors, untrained and/or unsound mind individuals. When I initially tried it with just one stepper motor and a linear ball bearing on the other side, it either failed the cut or tilted and got stuck on the linear bearing side since the top blade was only going down on one side. An M4 cage nut + screw secured with Loctite is used to make the side cutter blades position adjustable. A rising edge will trigger an interrupt signaling a normal button press. ST7735 driver rewritten, added display rotation functions. It is confusing for europeans. A DTR signal from the CP2102 module is used to auto reset the ESP after programming. I was fortunate enough to work in the business for a few years. In the end, I had a very simple, yet versatile stepper driver using a simple UART block only. Achim Dbler for the uGui graphical library, which I modified a little bit by adding symbol fonts, stripped system font to save flash space and a few other changes. Both, the input and output from the extruder use an M6 screws, which are drilled through with a 4mm drill. In addition the input terminal has a small window used with the IR sensor (diode + phototransistor) to detect the presence of the wire. Elecia White - for her command console code. In my early days I was doing hand assembly of MILspec aircraft and aerospace flight systems. Since the key press events are stored in a buffer, added a way to clear it out and discard any detected events. input voltage of 28V. The machine runs on an Arduino Nano, with stepper interface is via a pair of A4988 stepper drivers. It is not required for the operation, though. Kustaa Nyholm / SpareTimeLabs for the excellent tinyprintf library. Wire length, the length of the stripped portions, and number of wires to be made are dictated by input to a Nextion 2.8 touchscreen HMI. I admit this method does not work 100% reliably with thin wires like the 1mm solid copper one, hence I added an option to override that function in firmware. It provides a footprint for the module with all the required components and pins available on a header. Good stuff!! That's when I decided to go with two stepper motors on either side. I have always wanted to make a DIY cutter/stripper based upon my years of experience with cable assembly in the EMS world. Ingenious!!! (Comment Policy). These are the ones I tested. A4988 does not have such a feature, thus the fan is turned on when the motor is working. Cuts wire pieces in preset length and count. The prototype electronics was built on a home made dual layer PCB using the CY8CKIT-049 dev board, initially the A4988 stepper driver (changed to Trinamic TMC2130 Silent Step Stick), an SPI 12x128 TFT display, 4x4 keypad, MG996R servo (died shortly after), a 35W 15VDC switching power supply and a few other bits and pieces. Great work. UART uses a TX buffer and interrupts to make the operation non blocking and "set and forget" type. I like my wires this way. In addition the programmer is also an USB/UART bridge (UART_TX, UART_RX pins on the pic below). Engineer, maker of random contraptions, love learning about tech. The video below shows the build and the finished product in action. https://www.schleuniger.com/en-us/products/cut-strip/ecostrip-9380/. Nice. I am actually from the UK, but I use AWG because when I buy wires that's what is referred to. Clocked from a 120Hz clock source the Debouncer ensures a clean press detection. Once I got the prototype working, I started with a final PCB design. A PVC spacer and a larger washer secured with a shrink tube acts as a rotating platform for the spool. The plan was to make a base hardware which might be used for other stepper/servo related projects. The feeding mechanism employs a NEMA 17 stepper motor to pull wire through, using a timing belt-style pulley setup thats very similar to a 3D printer filament feeder. The remaining space was used to add a few more extras on the board, make it more versatile and useful for any potential future projects. Think about it a minute and youll understand why. If the motor could reverse after the strip cut (while holding the strippers closed) the machine could also remove the stripped end. If you are interested, in this video I explain the Arduino project in detail and how you can make it yourself! It helps the cut wire pieces land where they should. Dont let the trolls get to you! After a few trials I ended up using a much simpler and, as it turned out, effective way: one of the SCB components (Serial Communication Block) configured as plain UART. no more size adjustments. The throw of the cutter is controlled by a stepper motor partial closure nicks the insulation, while a full stroke cuts the wire off. One of the cleaner versions I have seen of the DIY cut and strip machine. Funny story, last week I added wire stripping bot to my project list. These jaws are then closed with a stepper motor and linkage system, cutting or stripping the wire as needed. An old printer is a good source for such diode + phototransistor modules, often used as paper presence detectors. So as soon as all the components are available you can start assembly the machine. Flipkart shall not assume any consequences, loss, damage or injury, that may arise from the violent or illegal use, or misuse of the product sold by the independent Sellers on the Flipkart platform. Single cut and rewind (remove the wire from the extruder) operations. Really, the only difference between a DIY and Professional version is the complex design that allows for repeatability and reliability. I have used a Schleuniger 9300 for years (surpassing 2 million cuts a few months ago) and I am always amazed at how simple the mechanics actually are. Virtualbox + Win7 or higher). New Automatic Wire Stripper Cutter Crimping Pliers, New Automatic Mini Wire Stripper Cutter Crimping Plier Multifunctionalh Tool. For more details on how professional machines do this, check out the video on the following page. Sometimes the coincidence of these articles are a bit creepy though. Valer liked Nysa: FPGA Development Environment. Chip tune factory for guitar: HEXE Sound Cartridge. a hard reset of the TMC2130 driver or a power cut off in case of servo malfunction. The base holding all the parts and most of the components are made of aluminum or brass. Added for potential future use of the board in projects using Bluetooth low energy connectivity. Using another hardware driven CS (chip select) line for the EEPROM was not possible due to routing restrictions. This decision can be reversed. Wim Van Gool has added a new log for Fri3d 2022 Badge. Mainly just for fun as the project is ideal for learning several different engineering aspects. I blamed my tools or the age of the wire many times, which I now know was just production variation. Such approach, together with using interrupts, flags and IO buffers allows to write most of the functions in a non blocking manner, using wait states as little as possible. You undertake that you will use the product for domestic, and/or agricultural purposes only and in a safe and legal manner, consistent with all applicable laws, safety rules, and good common sense. When you need to strip a bunch of wire to a certain length, you could bite the bullet and measure manually, then carefully cut over and over and over.
