    sO NICE BUFFER INTERFACE BOARD,DO U THINK IT'S WORKING WITH LINISTEPPER VER 2

    tHE SCHEMATIC DIAGRAM , it's nice but you should label,
    schemitt triger is for home limit switch,can you show the wiring for this interface board from switch to board and for buffer also show the step,dir,did you put enable ,mybe there's motor enable i've seen ,pin 14 is connected somewhere..
    if i get this , i will covert it to my
    own connection ,it's better to used terminal block Wago..

    what's is for resistor value ..and others


    anyone share the more easies,
    Where is the original schematic diagram or other Most clear

    switches can be hooded up many differnt ways...

    I have 3 home switches only, connected to pins 10, 11 , 12 of the parellel port, one for each axis. Each switch is conected to ground(pin 6 of IN connector) and the other end of the switchs to (1, 2, and 3 of the IN connector)

    On the X,Y,Z,W connectors on the BOB board pin 3 is DIR, and pin 4 is STEP

    The enable is on pin 1 of the X,YZ,W connectors it can be connected to ground by connecting jumper beween pins 1 and 2 of SV1, or by putting jumper between pins 2 and 3 of SV1 you can have the software control it by changing the state of pin 17 of the parallel port.

    ---- oops---- connecting pins 1 and 2 of SV1 will have no effect as the schematic is !!!.
    Pin 1 of SV1 should be connected to 5v in the schematic not to ground... I will change that in future updates..

    R1-R5 I'm going to use 1K resistors but anything between 1K to 100K should work..

    Caps are .1 mfd for the ones by the power pins of the IC's.
    C7 should be about 470mfd at a higher voltage than you plan to use for your motors.
    C5 100mfd at 25 volts or so..
    C6 10mfd at 16 volts
    C4 .1 mfd

    I already am using them on my current setup so I just thought I would stick with them as they see to be working OK.
    I'll attach a couple of pics of my current setup.

    I'm not planning to use cables... I designed the stepper boards so they would connect direcly to the BOB board at a 90 degree angle..

    Ya can do that before I upload new version.

But some people swear by them, so who am I to say otherwise?
    I havn't needed them yet either but didn't think it would hurt..
    The schmidt inputs I thought would be nice for noisy(electrically noisy that is) enviroments..

    You can post it if you like.. I'm just doing it for my own sake so...

    The connectors Sam is using are completely different.

    LINISTEPPER BUILT

    These are linistepper diriver, interface board and PIC microchip programmer microJDM (uJDM) I built. My questions are:
    1) I used PIC 16F628-041P instead of PIC 16F628A. Will it work?
    2) What's the correct stepper motor wiring for the linistepper version I built? I'm using a 5 wire stepper motor taken from an old printer.
    3)What's the correct software configuration for my interface board and driver?
    I need configurations for Linux EMC2, and KCAM and Mach3 under WinXP.

    All pictures you need are posted below.

    PS: Could you post screenshots of correct hardware and software configurations?

    No idea... probably.

    That depends on the motor. You have no info on the motor wiring? No part number on the motor? If not, this page may help you finger it out:

    Don't have anything for KCAM... If you work it out, please let us know.

    Nope. I don't have your motor or software (I use TurboCNC) or break out board or driver board.

    If they are 16F628-04 IP then NO they are only 4 mhz, you need at least 16 mhz parts.

    If you are using V1 software make sure the enable pins are at 5 volts.
    If you are using V2 software make sure the enable pins are at 0 volts.

    Took some time to figure out how to use Eagle-3D, but I like it.

    Here are a couple of pix's of the boards I'm working on.

    Anyone know where to find a 3d file for the 3 pin resonator
    like the one in the picture?

    By the way what is the best 16F6XX microchip for my linistepper, working with v1 or v2 software?

    I didn't think they made the 16F628 in 4MHz version? I thought they were all 16F628/20?

    The 16F628 will work ok provided it is the 20MHz version. The source code contains a #define already set up for 16F628. The Linisteppers were supplied with 16F628 for quite some time until the A version became more accessible. So either 16F628 or 16F628A will work ok, just check the define in the source code.

    Just checked the Digikey site and they still sell the 4mhz version..

    or you can try ebay search for 16F628A, it came up with 144 hits when I checked today.

    These are all unprogramed IC's so you need to program them with the linistepper code..

    Thank you very much! :-) Today I was lucky! I just came from the (only) shop having a 16F628A. I hope my micro JDM programmer works with the chip!

    Somebody help me

    I finally made a linistepper, and it mounts PIC 16F628A now, but stepper motor doesn't move:
    - when it's stopped, its shaft is locked
    - when it should run, the shaft vibrates.
    I tried to swap motor wires, but nothing changed, so I acquired some data by an oscilloscope. I burned LinistepperV2.hex on the microchip. The stepper motor is a NMB (minebea electronics) PM35S-048_HPL2 from an HP printer, an the software is KCAM . The beheaviour of linistepper is the same with PIC 16F628-04/P. I tested linistepper with PICs programmed and empty: the result is the same.
    Last three pictures are signals from the interface board (PMinMO 5 axis).
    What is the problem of my linistepper?
    PS: The pic programmer I used is uJDM (microJDM).
