Hello,
·· I am having trouble testing my CNC machine. Is there any programs (in Bs2·PBASIC)·for testing the CNC machine?
Any replies to this post would be greatly appreciated!

    For answers you need to provide more information. What troubles are you having, which machine are we talking about, what is the machine expecting for input and how is that input getting into the machine would be good for starters.

    any machine of which range is 22cm x 11cm the machine uses 3 steppers for x, y, and z axis, the steppers input 4 entrances each and they all have 4 parallel bridges.
    if u need more info please ask

    I'm not familiar with the "any machine" brand [noparse];)[/noparse]
    Seriously, every machine is going to be different. We need to know what type of signals it needs.
    Do you have a manual ? Can you post a link to it ?

    ·not really 'cause it's home made but the signal it recieves comes from the bs2px to bridge to stepper [noparse]/noparse]BS2PX--->4001 bridge--->step][noparse][[/noparse][img]http://forums.parallax.com/images/smilies/roll.gif[/img

    There is an example of stepper control with the basic stamp here. http://www.parallax.com/detail.asp?product_id=27964

    What's a "4001 bridge" ?

    Can you post a schematic ?

    I'm guessing he means a 1n4001 diode bridge?!

    What's the problem you're having with the CNC?
    You say it's homemade....have you in herited from someone else? Had it worked at one point?!
    Give us the symptom man!! [noparse];)[/noparse]

    Since it's connected to a stamp, do you have the code "some person" used to program that stamp? If not and you're thinking you can grab the code off the stamp...sorry, can't do that!

    The more information you provide us, the better we can help you!

    ·The problems r:
    1.·I dont have the code for BS2PX
    2. the·4001 (logical or gate) is transmitting but not from the stamp instead from the 4 10uf capacitors that i put for power brekage (ex. OR --/\/\/\
    < stepper
    ····················································· 1K···· |··················································
    ······························································· <--->CAP - (negative side connected to step coils)



    ·(5V/1000 = X 1000)·= 5mA flowing into OR gate

    I hope your not expecting to move a stepper motor with 5mA from a CD4001 gate IC ?
    I assume you are using uni-polar steppers (5 or 6 wires) ?
    Your ascii drawing didn't come out right.
    Did you built this ? Or did someone else ?

    i did build it with some modifications. The IC4001 wasn't my idea and yes i am using unipolar stepper motors
    the only modification i did was instead of using a PIC and a SX24
