Stepper controllers can be STRONG, smooth and SMART!

Well reviewed design:

• Open Source! Circuit Diagram, PCB (Board) Layout, and PIC Software all available online. (Proceeds support PICList.com)
• Standard step + direction inputs easy connection to a parallel port for up to 7 units.
• Use with standard CNC programs like TurboCNC
• Uses standard Unipolar (5 to 8 wire) stepper motors. Not for Bipolar (4 wire)
• Complete tutorial explains How the board works. Runs from your regulated +5v supply

Using the best components:

• Rugged: 5A 100v drivers to drive 1.5A/phase or more at 4v to 35v
• Smart: on-board PIC microcontroller. Comes pre-programmed. Active user groups and tons of code available.
• Solid: PCB with silkscreen and solder mask. Hard to damage and easy to repair

3 current levels, 1200 steps, without linear ramping.

Supports the standard modes:

• 200 step - full step
• 400 step - half step (with Full Torque)
• 1200 step - microstep 6th!
• 3600 step - microstep 18th!

9 current levels, 3600 steps, with linear ramping!

And some hard to find "magic" modes:

• NO STEP - stepless operation via constant current linear smoothing
• High-Torque half stepping
• low power "hold" mode

  Hello,

  Received your kit today (saturdaymorning 9 Nov.) Thank you Verry Much!

  Looks verry Proffesional made!
  I do not have the time at the moment to build an test it and i don't have the alluminium heatsink at home

  i have placed the components on the board all fits well i think except C3 holes are 2,54mm wide and should be 5,08mm wide {Ed: Component changes caused that... The leads can be bent to fit for now}

  also it would be better to place picture off the caps position on your kitassemble page people look better than they read or place caps + - on the silkscreen off the board {Ed: Done!}

  maybe you could give some more info/pictures about the resistors and colors on your kit assemble page maybe a picture with lines outside the picture with describing text off resistors (colors) {Ed: Done!}

  think this could help other people making mistakes placing components

  verry nice kit

  question where do you get this good quality pcb board made?? {Ed: GRIN!}

  Greetings luberth

• Matthew Armistead+ says: "Kits arrived today! Didn't choose FedEx option, but they still got here fast! Thanks! - "
   
• JB says:" Thanx....... I got home yesterday, and they were already there! BOY, that was fast!!! I have got to say that they are good looking kits, and will serve the purpose well, I'm sure. Thanx again" {JB ordered with the fedex option... we don't always get orders out the same day, but we do try.}
   
• Don Pastuck says: "Give me a price on (6) more plus shipping. Ground OK no rush for these. Board works like a charm when you put the connectors on the right direction." {I'm pleased that the board worked well and that I'm not the only person in the world who manages to put the connectors on backwards from time to time! <GRIN>}
   
• Norbert says: "I GOT ALL THREE BOARDS RUNNING AND THEY WORK ABSOLUTELY MARVELLOUSLY. PLEASE ACCEPT MY COMPLIMENTS FOR THIS EXCLLENT TECHNOLOGY."
   
• Vince Negrete says: "Hi James, Just got the kits after 2pm today, thank you for not delaying shipping. I was worried since I never heard back from you after payment. Thanks man. Nice kit.!"
   
• John Papin says: "Just to let you know I received your boards. Thanks again. Really nice work. "
   
• Earl says: "...I layout boards for a living and was impressed with your layout.... " {Romans layout, but thanks!}
   
• Martjin Mulder says: "Hi James, I did some homework, i will order the bare boards, program the pic proccessor ... and snif in the [junkbox for parts]... Thanks for youre support so far ! I'll order the boards right away."
