Lini- stepper controller kit drives cnc lath / mill
Stepper controllers can be STRONG, smooth and SMART!
The assembled kit, ready to clamp to a heatsink and connect to power, your PC and a motor.
This controller KIT is based on a well reviewed design: Check out the gallery!
* 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., how to assemble the kit and how to power it up! Runs from your regulated +5v supply
* Rugged: 5A 100v drivers to drive 1.5A/phase or more at 4v to 35v
* Solid: PCB with silkscreen and solder mask. Hard to damage and easy to repair
* 400 step - half step (with Full Torque)
* 1200 step - microstep 6th!
* 3600 step - microstep 18th!
Linear stepping at 3600. (thanks to Sam Colwell!)
And some hard to find "magic" modes:
* NO STEP - stepless operation via constant current linear smoothing
* Brian Bartholomew says: "My compliments on the high quality of the kits! I can't imagine how you do it at that price, but I am thrilled that you do."
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
question where do you get this good quality pcb board made?? {Ed: GRIN!}
* Sam Colwell sent pictures of his CNC machine. "Thanks again for your linistepper kits. They were a pleasure to construct and use, and your documentation is excellent."
* Dustin Nelson says "THESE CONTROLLERS ARE AWESOME. I BOUGHT THREE THAT ARE RUNNING A SMALL MILLING MACHINE." (as he orders 3 more)
* Norbert says: "I GOT ALL THREE BOARDS RUNNING AND THEY WORK ABSOLUTELY MARVELLOUSLY. PLEASE ACCEPT MY COMPLIMENTS FOR THIS EXCLLENT TECHNOLOGY."
* 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."
* Hugh says: "Thank YOU very much - nice package for hobbyists -"
You can end up with a kit that cost you: NOTHING!
Kits now for sale! Price increasing soon!
PCB and full kit of parts to build your own!
You supply voltages, heat sink & mounting bracket, unipolar stepper motor, and step/direction signals.
Priority Mail (in the USA only)
Also available: Set of 3 Printed Circuit Boards for $35.00. These are VERY well made boards and are certainly worth the price IF you have a well stocked scrap box to populate them. However, you will find our kit price of $75 for 3 complete kits is MUCH LESS than the cost of parts and PCBs, AND the PIC comes already programmed!
