A dyesublimation printer or dyesub printer is a printer which employs a printing process that uses heat to transfer dye to a medium such as a plastic card, paper. Describes the stepper system that Mel Bartels developed starting in the 1980s. The system quickly become popular and open source, both hardware and software. The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse or 0 to 3. V pulse if you solder. UBW USB Bit. Whacker project to solve his problem of disappearing parallel. The UBW design has exceeded all of my expectations. As well as meeting the original design objectives, it has proven. But there was. still a problem Bruce traditionally used the UCN5. B stepper motor. driver chip for his Egg. Bot. classes because it is easily breadboardable and very simple to. Unfortunately, they are now 1. Bruce wondered if I could design and build a replacement. And so now we have the Easy. Driver design. There is now an official Egg. Bot. that you can purchase It uses an Ei. Bot. Board, which I. UBW 2 Big. Easy. Drivers. The Ei. Bot. Board is. Spark. Fun. and Evil Mad. Scientists. Knock Off Easy Drivers. Over the years, the Easy Driver has become popular enough that. I am. flattered, truly I am. And this is open source hardware after all. However, any other manufacturer of Easy Drivers besides Spark. Fun. and Seeed. Studio are doing so without supporting me in any way. Driver Parallel Lines Heat RashI then have fewer resources to design new OSHW. The. license that the Easy. Driver is released under requires at least. These knock off manufacturers will normally. Schmalz. Haus. com silk screen before they build. Electronics. DIY. It appears that Electronics DIY has decided to build. Easy Drivers, taking off the Schmalz Haus part of the silk. This is in violation of the. There are lots of others too all of the very. Easy. Drivers that are now on EBay, Amazon, and. Aliexpress are knock offs. None of them support me in any way, but. I end up fielding tech support for their boards because people. So please help support OSHW and buy. Spark. Fun or Seeed. Studio. They are fantastic and not only. OSHW but actively support designers like. Quickar Electronics, Inc. ICs. Lancaster You Dont Really Want A Patent, Do You Don Lancasters Patent Avoidance Library. Don discusses many of the pitfalls of obtaining and keeping patents. Introduction Parallel Port 3 Axis CNC Driver, OptoIsolated, Unipolar Steppers. Quick Specs. Each Easy. Driver can drive up to about 7. A per phase of a bi polar. It defaults to 8 step microstepping mode. So if your. motor is 2. Easy. Driver. This setting can be easily overridden by tying. MS1 andor MS2 pin to ground to set the driver to use 18, 14. See the datasheet for the table of values. It is a chopper microstepping driver based on the Allegro. A3. 96. 7 driver chip. For the complete specs of the design, read. A3. 96. 7 datasheet. It has a variable max current from about. Aphase to 7. 50m. Aphase. It can take a maximum motor drive. V, and includes on board 5. V regulation, so only. The best part low cost. The parts cost is. Quick Pin Description. Please see the Allego A3. The Easy Driver is basically just a breakout. However, if all you need is a. GND There are three GND Ground pins on the Easy Driver. They are all connected together inside the board. Connect the. negative side of your power supply, as well as from any other. Easy Driver to one or more of. GND pins. M This is the power input to the Easy Driver. Connect this. to the positive power supply lead. This should be a 6. V to 3. 0V. 2. A or more power supply that is clean low ripple. A and B four pins These are the motor connections. See. below diagrams for how to hook these up. A and B are the two. Make CERTAIN. that this connection to the motor is solid, and NOT through a. STEP This needs to be a 0. V to 5. V or 0. V to 3. V if youve. set your Easy Driver that way digital signal. Each rising edge. DIR Direction This needs to be a 0. V to 5. V or 0. V to 3. V. if youve set your Easy Driver up that way digital signal. The. level if this signal highlow is sampled on each rising edge. STEP to determine which direction to take the step or. Thats it those are the only signals that you absolutely need. All the rest below are optional in other. Easy Driver sets them to reasonable default values. MS1MS2 These digital inputs control the microstepping mode. Possible settings are MS1MS2 full step 0,0, half step. RST reset This normally high input signal will reset the. SLP sleep This normally high input signal will minimize. ENABLE This normally low input signal will disable all. PFD This one is complicated please see the datasheet for. We default it to slow decay mode, but you can. R1. 75. V This is an OUTPUT pin that will provide either 5. V. default or 3. V from the voltage regulator, at a small amount.

Oh, so awesome where can I buy one I do not sell Easy. Driver boards. This design is open source hardware. It was developed in. Spark. Fun, and they manufacture and sell it. Im providing Eagle schematic and board layouts as well as a Bill Of. Materials and instructions on how to build and use the design if you. If you do. decide to manufacture the Easy. MX Vs ATV Unleashed - PC - ISO. Driver for yourself or for sale. I can continue. to provide support to Easy Driver users, so contact me. Spark. Fun DOES sell Easy. Driver. boards and theyre only 1. Also, please note that a Bigger, Badder, and all around Better. Easy Driver has been designed. Its called the Big. Easy Driver BED. You can read all about it at the Schmalz Haus Big Easy Driver. News 0. 81. 82. Added a new. FAQ below about the two jumpers on the Easy Driver. Q1. 51. 11. 62. I did some measurements of temperature and current draw. Spark. Fun stepper motor and an Easy. Driver. See the results. Question 1. 4. 1. Xavier wrote a great tutorial on using Easy. Drivers with Arduino. My. DIYCNC is. now using Easy Drivers in some of their products, and is even. Check out their cool CNC. New Easy. Driver and Big Easy Driver Examples page with Arduino code. On a whim, I tested to see what the lowest voltage is. Easy Driver could run on. It had no problem running down to. V this is with a factory fresh Easy Driver 4. And, it ran. really cool. Note that youll need a very low coil resistance motor. Very minor update to schematic and BOM for Easy. Driver. v. 4. 4 C3 is now 4. F. Spark. Fun has always build them with 4. F. caps, but Ive updated the documents to reflect this. It was. previously listed as 1. F. 0. 81. 91. 1 We now have an Eagle. Easy. Driver v. 4. Easy. Drivers on their board. It appears that there are two different types of current. Easy. Driver v. 4. If you. have one with the squarish white box of a pot as per the v. MIN and MAX silkscreen. The previous version of the pot see v. MIN and MAX silk screen. I dont know why the pot vendors. Anyway, be careful. Note, the board is identical, its only that one. Note that v. 4. 3 and v. MIN and MAX words backwards on the board. So if you have a small. CAREFUL The likely result is that you will set it to MIN. A will go through your motor, and it will get quite. There will be a new v. Version 4. 3 has now been released to Spark. Fun only. difference being two mounting holes. After a very long process due to my procrastination and. Easy. Driver In very close collaboration with. Spark. Fun, Im happy to release version 4. This new. version has several very nice new features, and still has the same. Thanks Spark for making this design available to. Some pictures on this page are from Spark. Fun. 0. 91. 70. Daniel Thompson has created an awesome. Easy. Driver with an Arduino. Thanks Daniel NOTE Many people attempt this setup without connecting the grounds. Easy. Driver and Arduino or other pulse source.
