    Thank you. I have been reading the various Gecko drivers specs, and just read through the pasted wiring diagrams section. With all of the protections on this driver board (203v), it looks like a break out board is no longer needed ? or is that only if you have the G Rex 100 ?

    A breakout board is a convenience that shouldn't be overlooked. It beats the daylights out of the alternative; wiring directly from a parallel port. Otherwise a G203V is perfectly happy running from a directly wired parallel port or from any other step/direction source so long as the step/dir signals are between 2.5V to 5V in amplitude.

    Hey Mariss,
    My curiosity is getting the best of me. I sent a 203v back to you that was acting strange, told you I would be out of town and to hold the drive.

    Still out of town but have access to e-mail and this site. Any news on the drive yet?

    Even when I can't play I'm thinking about it!

    thanks,
    jb

    jb,

    Under what name or company name was it returned? That is the only way I can find it in the system to give you its disposition.

    jhowelb,

    You really have to try much harder to kill a G203V. Your drive came up as "no problem found". That means there was zero, zilch, nada, nothing, goose-egg wrong with it.

    What was wrong was your return address. The drive came back. Please contact me off list.

    Mariss

    As to the malfunctioning Gecko, it was deemed to be "within specs" and was returned to me presumably without alteration plus an extra new one "as a customer service" because of some confusion in getting the drive shipped.

    The original one is still in the shipping onvelope but the new one is installed and happily functioning as nicely as the other "old" one,

    I'm a happy camper!

    Alain26,

    There is something new. The yellow LED lights when your motor is going fast enough to develop full power.

    Merry Christmas everyone!!!

    I May have blown a G203V...
    I have sent a mail to gecko yesteday, but no answer yet (its chrismas time i guess).

    Is there anything else i can do?
    This is my mail:

    Hi

    Im having some problems with one of my G203V's.

    The drive has been working for 3 weeks now, but laitly the motor
    connected has stopped for a secound or two
    and then started again. Now it doesn't work at all.

    When i switch on the power, it doesn't do the same startup prosedure
    at the other ones do.
    The green ligth just comes directly on, and after alittle while the
    red one also comes on.
    I should also mention that it looks like the green and the red ligth
    is weaker than in the other drives.
    I can feel the drive is getting hotter than the other ones, i guess 40C.
    There is no torque in the motor at any time.
    The disable terminal is not connected.
    I have removed the internal fuse and mesured it, it is ok.

    The drive was connected to a 3,25A motor
    Witch if i understand correctly you should multiply with 0.717 to get
    the current in series.
    This means 2,3A.
    My resistor should then be 23k (i have 22k connected, also checked
    that with multimeter).

    To eliminate any problems with the wiring, i changed the drive with
    one of the others
    Now the problem moves with the drive.

    I feel i have done everything i can do alone
    And i would appreciate if you could advise me what to do next.

    Talking g203v

    Hi Mariss, I received my second 203v about a week or two ago and it was unfortunately DOA. Being so far away (South Africa) I decided to have a look at it myself. When power was applied, the green LED flashed on briefly then all was dead. While inspecting it I pressed lightly on various components and found that it came to life when pressing a component near the voltage regulator. It was a chip with 2 legs on one side and 3 on the other. On closer inspection (lots of jewellers loupes etc) the solder had a goldish tint and had a sort of matt texture. After murdering a soldering iron with a file I had a small enough tip and managed to re-solder the thing. Happiness!!!! Green and red lights flashed and glowed and steppers turned. Great relief as this would have caused at least a couple of weeks delay. Many thanks for a great product!
    Best regards
    Les

    moxy,

    Sorry about that. ROHS solder doesn't wet as well as normal solder does. It seems one terminal of the SOT-23 was not wetted and was making a cold connection. This happens once in a long while with lead-free solder, never happened with regular solder. I'm glad you spotted it and corrected it. Lead-free solder (Sn 96.5%, Ag 3%, Cu 0.5%) has a characteristic matte finish.

    joakim,

    Please return the drive for evaluation.

    Mariss

    I see this RoHs stuff is giving people problems, I think a big breath of LA air is worse.

    Thanx Marris

    I'll send it today.
    I also opened it, but i didn't see any obvious faults.

    I just sent one back yesterday. With the holidays, it does take some time to get a reply, but the website shows they are closed on some days, so emails don't close and there is likely some catching up to be done when they all get back in the office.

    I got a reply from Marcus.

    He told me what to do with the 203V.
    It is in the mail.

    This one isn't actually fried I don't think, but doesn't function. It still shows a green LED.

    Here is a copy of the email I sent.

    I found out today after thoroughly testing and rewiring, that one of my
    203V's isn't working. I did a swap with another good drive, a 201, and
    the machine is working now. The 201 is out of my router. I went through
    the troubleshooting guide for the 203's on your yahoo Support Group. It
    is getting a green light, so it must be something minor. The fuse
    appears intact. With all power off, I checked across the phases on all
    three gecko's at the pins behind the terminals. I got zero ohms from the
    wires in the same windings and read 97 or some percent of that value to
    the other winding pins. These readings were the same for both good
    203V's. I only read about 75 or some percent of that value across the
    bad one.
    I would like to know how I go about sending this one back for repair?
    I did order two more today. I understand it is the holidays, and I will
    be able to run both machines off of one control box until the others
    arrive. Thanks a bunch.


    Here is an image of how the drives were mounted. I have since changed the wiring around some. Motor wires and PS wires are all a little neater and the switch wires no longer run across the top of the X gecko.
    This bad Gecko was in the Y position initially. I also added more terminal blocks to make the connections better for power and ground from the PS. It BTW is a 72 VDC @ 12 A. It produces lower voltages as the motor amp draw increases I think. Running 3 amp motors with a 35.2K resistor on each drive.

    I thought I would update this. I got an email and a notification from Gecko today. It said "Stepper Drive -- Returned for evaluation. An Intermittently working IC was found.
    IC replaced, and drive repaired.

    It's on it's way back @ no charge. Thanks a bunch, Mariss.

    Bloody horrible stuff, it's banned in any military application because of tin whiskers. Though now all the standard components are pre-tinned with the stuff we're buggered.
